| 277 | * camera device can pass as part of the capture session initialization.</p> |
| 278 | * |
| 279 | * <p>This list includes keys that are difficult to apply per-frame and |
| 280 | * can result in unexpected delays when modified during the capture session |
| 281 | * lifetime. Typical examples include parameters that require a |
| 282 | * time-consuming hardware re-configuration or internal camera pipeline |
| 283 | * change. For performance reasons we suggest clients to pass their initial |
| 284 | * values as part of {@link SessionConfiguration#setSessionParameters}. Once |
| 285 | * the camera capture session is enabled it is also recommended to avoid |
| 286 | * changing them from their initial values set in |
| 287 | * {@link SessionConfiguration#setSessionParameters }. |
| 288 | * Control over session parameters can still be exerted in capture requests |
| 289 | * but clients should be aware and expect delays during their application. |
| 290 | * An example usage scenario could look like this:</p> |
| 291 | * <ul> |
| 292 | * <li>The camera client starts by quering the session parameter key list via |
| 293 | * {@link android.hardware.camera2.CameraCharacteristics#getAvailableSessionKeys }.</li> |
| 294 | * <li>Before triggering the capture session create sequence, a capture request |
| 295 | * must be built via {@link CameraDevice#createCaptureRequest } using an |
| 296 | * appropriate template matching the particular use case.</li> |
| 297 | * <li>The client should go over the list of session parameters and check |
| 298 | * whether some of the keys listed matches with the parameters that |
| 299 | * they intend to modify as part of the first capture request.</li> |
| 300 | * <li>If there is no such match, the capture request can be passed |
| 301 | * unmodified to {@link SessionConfiguration#setSessionParameters }.</li> |
| 302 | * <li>If matches do exist, the client should update the respective values |
| 303 | * and pass the request to {@link SessionConfiguration#setSessionParameters }.</li> |
| 304 | * <li>After the capture session initialization completes the session parameter |
| 305 | * key list can continue to serve as reference when posting or updating |
| 306 | * further requests. As mentioned above further changes to session |
| 307 | * parameters should ideally be avoided, if updates are necessary |
| 308 | * however clients could expect a delay/glitch during the |
| 309 | * parameter switch.</li> |
| 310 | * </ul> |
| 311 | * |
| 312 | * <p>The list returned is not modifiable, so any attempts to modify it will throw |
| 313 | * a {@code UnsupportedOperationException}.</p> |
| 314 | * |
| 315 | * <p>Each key is only listed once in the list. The order of the keys is undefined.</p> |

| 836 | * <p>For the high speed video use case, the application must |

| 838 | * preview streams and setup the recording requests. For example, if the application intends |
| 839 | * to do high speed recording, it can select the maximum size reported by this metadata to |
| 840 | * configure output streams. Once the size is selected, application can filter this metadata |
| 841 | * by selected size and get the supported fps ranges, and use these fps ranges to setup the |
Yin-Chia Yeh | 12da140 | 2014-07-15 10:37:31 -0700 | [diff] [blame] | 842 | * recording requests. Note that for the use case of multiple output streams, application |
Zhijun He | fab663e | 2015-05-26 19:46:31 -0700 | [diff] [blame] | 843 | * must select one unique size from this metadata to use (e.g., preview and recording streams |
| 844 | * must have the same size). Otherwise, the high speed capture session creation will fail.</p> |
| 845 | * <p>The min and max fps will be multiple times of 30fps.</p> |
| 846 | * <p>High speed video streaming extends significant performance pressue to camera hardware, |
| 847 | * to achieve efficient high speed streaming, the camera device may have to aggregate |
| 848 | * multiple frames together and send to camera device for processing where the request |
| 849 | * controls are same for all the frames in this batch. Max batch size indicates |
| 850 | * the max possible number of frames the camera device will group together for this high |
| 851 | * speed stream configuration. This max batch size will be used to generate a high speed |
| 852 | * recording request list by |

Zhijun He | fab663e | 2015-05-26 19:46:31 -0700 | [diff] [blame] | 854 | * The max batch size for each configuration will satisfy below conditions:</p> |
| 855 | * <ul> |
| 856 | * <li>Each max batch size will be a divisor of its corresponding fps_max / 30. For example, |
| 857 | * if max_fps is 300, max batch size will only be 1, 2, 5, or 10.</li> |
| 858 | * <li>The camera device may choose smaller internal batch size for each configuration, but |
| 859 | * the actual batch size will be a divisor of max batch size. For example, if the max batch |
| 860 | * size is 8, the actual batch size used by camera device will only be 1, 2, 4, or 8.</li> |
| 861 | * <li>The max batch size in each configuration entry must be no larger than 32.</li> |
| 862 | * </ul> |
| 863 | * <p>The camera device doesn't have to support batch mode to achieve high speed video recording, |
| 864 | * in such case, batch_size_max will be reported as 1 in each configuration entry.</p> |
| 865 | * <p>This fps ranges in this configuration list can only be used to create requests |
| 866 | * that are submitted to a high speed camera capture session created by |
| 867 | * {@link android.hardware.camera2.CameraDevice#createConstrainedHighSpeedCaptureSession }. |
| 868 | * The fps ranges reported in this metadata must not be used to setup capture requests for |

| 1819 | * <p>This is a subset of android.request.availableRequestKeys which |
| 1820 | * contains a list of keys that are difficult to apply per-frame and |
| 1821 | * can result in unexpected delays when modified during the capture session |
| 1822 | * lifetime. Typical examples include parameters that require a |
| 1823 | * time-consuming hardware re-configuration or internal camera pipeline |
| 1824 | * change. For performance reasons we advise clients to pass their initial |
Chien-Yu Chen | a1d1d5b | 2018-01-03 12:14:53 -0800 | [diff] [blame] | 1825 | * values as part of |

| 1829 | * {@link SessionConfiguration#setSessionParameters }. |
| 1830 | * Control over session parameters can still be exerted in capture requests |
| 1831 | * but clients should be aware and expect delays during their application. |
| 1832 | * An example usage scenario could look like this:</p> |
| 1833 | * <ul> |
| 1834 | * <li>The camera client starts by quering the session parameter key list via |
| 1835 | * {@link android.hardware.camera2.CameraCharacteristics#getAvailableSessionKeys }.</li> |
| 1836 | * <li>Before triggering the capture session create sequence, a capture request |
Chien-Yu Chen | a1d1d5b | 2018-01-03 12:14:53 -0800 | [diff] [blame] | 1837 | * must be built via |
| 1838 | * {@link CameraDevice#createCaptureRequest } |
| 1839 | * using an appropriate template matching the particular use case.</li> |
Emilian Peev | 75a5570 | 2017-11-07 16:09:59 +0000 | [diff] [blame] | 1840 | * <li>The client should go over the list of session parameters and check |
| 1841 | * whether some of the keys listed matches with the parameters that |
| 1842 | * they intend to modify as part of the first capture request.</li> |
| 1843 | * <li>If there is no such match, the capture request can be passed |
Chien-Yu Chen | a1d1d5b | 2018-01-03 12:14:53 -0800 | [diff] [blame] | 1844 | * unmodified to |
| 1845 | * {@link SessionConfiguration#setSessionParameters }.</li> |
Emilian Peev | 75a5570 | 2017-11-07 16:09:59 +0000 | [diff] [blame] | 1846 | * <li>If matches do exist, the client should update the respective values |
Chien-Yu Chen | a1d1d5b | 2018-01-03 12:14:53 -0800 | [diff] [blame] | 1847 | * and pass the request to |

Emilian Peev | 75a5570 | 2017-11-07 16:09:59 +0000 | [diff] [blame] | 1849 | * <li>After the capture session initialization completes the session parameter |

Zhijun He | 513f7c3 | 2015-04-24 18:23:54 -0700 | [diff] [blame] | 2173 | * output format/size combination.</p> |
Igor Murashkin | a23ffb5 | 2014-02-07 18:52:34 -0800 | [diff] [blame] | 2174 | * <p>A stall duration is how much extra time would get added |
| 2175 | * to the normal minimum frame duration for a repeating request |
| 2176 | * that has streams with non-zero stall.</p> |
| 2177 | * <p>For example, consider JPEG captures which have the following |
| 2178 | * characteristics:</p> |
| 2179 | * <ul> |
| 2180 | * <li>JPEG streams act like processed YUV streams in requests for which |
| 2181 | * they are not included; in requests in which they are directly |
| 2182 | * referenced, they act as JPEG streams. This is because supporting a |
| 2183 | * JPEG stream requires the underlying YUV data to always be ready for |
| 2184 | * use by a JPEG encoder, but the encoder will only be used (and impact |
| 2185 | * frame duration) on requests that actually reference a JPEG stream.</li> |
| 2186 | * <li>The JPEG processor can run concurrently to the rest of the camera |
| 2187 | * pipeline, but cannot process more than 1 capture at a time.</li> |
| 2188 | * </ul> |
| 2189 | * <p>In other words, using a repeating YUV request would result |
| 2190 | * in a steady frame rate (let's say it's 30 FPS). If a single |
| 2191 | * JPEG request is submitted periodically, the frame rate will stay |
| 2192 | * at 30 FPS (as long as we wait for the previous JPEG to return each |
| 2193 | * time). If we try to submit a repeating YUV + JPEG request, then |
| 2194 | * the frame rate will drop from 30 FPS.</p> |
| 2195 | * <p>In general, submitting a new request with a non-0 stall time |
| 2196 | * stream will <em>not</em> cause a frame rate drop unless there are still |
| 2197 | * outstanding buffers for that stream from previous requests.</p> |
| 2198 | * <p>Submitting a repeating request with streams (call this <code>S</code>) |
| 2199 | * is the same as setting the minimum frame duration from |
| 2200 | * the normal minimum frame duration corresponding to <code>S</code>, added with |
| 2201 | * the maximum stall duration for <code>S</code>.</p> |
| 2202 | * <p>If interleaving requests with and without a stall duration, |
| 2203 | * a request will stall by the maximum of the remaining times |
| 2204 | * for each can-stall stream with outstanding buffers.</p> |
| 2205 | * <p>This means that a stalling request will not have an exposure start |
| 2206 | * until the stall has completed.</p> |
| 2207 | * <p>This should correspond to the stall duration when only that stream is |
| 2208 | * active, with all processing (typically in android.*.mode) set to FAST |
| 2209 | * or OFF. Setting any of the processing modes to HIGH_QUALITY |
| 2210 | * effectively results in an indeterminate stall duration for all |
| 2211 | * streams in a request (the regular stall calculation rules are |
| 2212 | * ignored).</p> |
| 2213 | * <p>The following formats may always have a stall duration:</p> |
| 2214 | * <ul> |

| 2319 | * <ul> |
| 2320 | * <li>The HAL may choose the aspect ratio of each Jpeg size to be one of well known ones |
| 2321 | * (e.g. 4:3, 16:9, 3:2 etc.). If the sensor maximum resolution |
| 2322 | * (defined by {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize}) has an aspect ratio other than these, |

| 2324 | * <li>Some hardware JPEG encoders may have pixel boundary alignment requirements, such as |
| 2325 | * the dimensions being a multiple of 16. |
| 2326 | * Therefore, the maximum JPEG size may be smaller than sensor maximum resolution. |
| 2327 | * However, the largest JPEG size will be as close as possible to the sensor maximum |
| 2328 | * resolution given above constraints. It is required that after aspect ratio adjustments, |
| 2329 | * additional size reduction due to other issues must be less than 3% in area. For example, |
| 2330 | * if the sensor maximum resolution is 3280x2464, if the maximum JPEG size has aspect |
| 2331 | * ratio 4:3, and the JPEG encoder alignment requirement is 16, the maximum JPEG size will be |

| 2606 | * application of any geometric distortion correction.</p> |
| 2607 | * <p>This is the rectangle representing the size of the active region of the sensor (i.e. |
| 2608 | * the region that actually receives light from the scene) before any geometric correction |
| 2609 | * has been applied, and should be treated as the active region rectangle for any of the |

| 2611 | * correction map, and radial distortion fields) treats the top, left of this rectangle as |
| 2612 | * the origin, (0,0).</p> |
| 2613 | * <p>The size of this region determines the maximum field of view and the maximum number of |
| 2614 | * pixels that an image from this sensor can contain, prior to the application of |
| 2615 | * geometric distortion correction. The effective maximum pixel dimensions of a |
| 2616 | * post-distortion-corrected image is given by the {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize} |
| 2617 | * field, and the effective maximum field of view for a post-distortion-corrected image |
| 2618 | * can be calculated by applying the geometric distortion correction fields to this |
| 2619 | * rectangle, and cropping to the rectangle given in {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize}.</p> |
| 2620 | * <p>E.g. to calculate position of a pixel, (x,y), in a processed YUV output image with the |
| 2621 | * dimensions in {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize} given the position of a pixel, |
| 2622 | * (x', y'), in the raw pixel array with dimensions give in |
| 2623 | * {@link CameraCharacteristics#SENSOR_INFO_PIXEL_ARRAY_SIZE android.sensor.info.pixelArraySize}:</p> |
| 2624 | * <ol> |
| 2625 | * <li>Choose a pixel (x', y') within the active array region of the raw buffer given in |
| 2626 | * {@link CameraCharacteristics#SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE android.sensor.info.preCorrectionActiveArraySize}, otherwise this pixel is considered |
| 2627 | * to be outside of the FOV, and will not be shown in the processed output image.</li> |
| 2628 | * <li>Apply geometric distortion correction to get the post-distortion pixel coordinate, |
| 2629 | * (x_i, y_i). When applying geometric correction metadata, note that metadata for raw |
| 2630 | * buffers is defined relative to the top, left of the |
| 2631 | * {@link CameraCharacteristics#SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE android.sensor.info.preCorrectionActiveArraySize} rectangle.</li> |
| 2632 | * <li>If the resulting corrected pixel coordinate is within the region given in |
| 2633 | * {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize}, then the position of this pixel in the |
| 2634 | * processed output image buffer is <code>(x_i - activeArray.left, y_i - activeArray.top)</code>, |
| 2635 | * when the top, left coordinate of that buffer is treated as (0, 0).</li> |
| 2636 | * </ol> |
| 2637 | * <p>Thus, for pixel x',y' = (25, 25) on a sensor where {@link CameraCharacteristics#SENSOR_INFO_PIXEL_ARRAY_SIZE android.sensor.info.pixelArraySize} |
| 2638 | * is (100,100), {@link CameraCharacteristics#SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE android.sensor.info.preCorrectionActiveArraySize} is (10, 10, 100, 100), |
| 2639 | * {@link CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize} is (20, 20, 80, 80), and the geometric distortion |
| 2640 | * correction doesn't change the pixel coordinate, the resulting pixel selected in |

| 2642 | * with dimensions given in {@link CameraCharacteristics#SENSOR_INFO_PIXEL_ARRAY_SIZE android.sensor.info.pixelArraySize}, and would be (5, 5) |
