| * <p>We define the expected processing pipeline below. For consistency |

| * {@link CaptureRequest#COLOR_CORRECTION_TRANSFORM android.colorCorrection.transform} will still be provided by the |
| * camera device (in the results) and be roughly correct.</p> |
| * <p>Switching to TRANSFORM_MATRIX and using the data provided from |
| * FAST or HIGH_QUALITY will yield a picture with the same white point |

| * <pre><code>{@link CaptureRequest#COLOR_CORRECTION_GAINS android.colorCorrection.gains} = [ R G_even G_odd B ] |
| * </code></pre> |
| * <p>where <code>G_even</code> is the gain for green pixels on even rows of the |
| * output, and <code>G_odd</code> is the gain for green pixels on the odd rows. |
| * These may be identical for a given camera device implementation; if |
| * the camera device does not support a separate gain for even/odd green |
| * channels, it will use the <code>G_even</code> value, and write <code>G_odd</code> equal to |
| * <code>G_even</code> in the output result metadata.</p> |
| * <p>The matrices for color transforms are defined as a 9-entry vector:</p> |
| * <pre><code>{@link CaptureRequest#COLOR_CORRECTION_TRANSFORM android.colorCorrection.transform} = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ] |
| * </code></pre> |

| * to output linear sRGB, <code>P_out = [ r' g' b' ]</code>,</p> |
| * <p>with colors as follows:</p> |

| * g' = I3r + I4g + I5b |
| * b' = I6r + I7g + I8b |

| * <p>The maximum frame rate that can be supported by a camera subsystem is |
| * a function of many factors:</p> |
| * <ul> |
| * <li>Requested resolutions of output image streams</li> |
| * <li>Availability of binning / skipping modes on the imager</li> |
| * <li>The bandwidth of the imager interface</li> |
| * <li>The bandwidth of the various ISP processing blocks</li> |
| * </ul> |
| * <p>Since these factors can vary greatly between different ISPs and |
| * sensors, the camera abstraction tries to represent the bandwidth |
| * restrictions with as simple a model as possible.</p> |
| * <p>The model presented has the following characteristics:</p> |
| * <ul> |
| * <li>The image sensor is always configured to output the smallest |
| * resolution possible given the application's requested output stream |
| * sizes. The smallest resolution is defined as being at least as large |
| * as the largest requested output stream size; the camera pipeline must |
| * never digitally upsample sensor data when the crop region covers the |
| * whole sensor. In general, this means that if only small output stream |
| * resolutions are configured, the sensor can provide a higher frame |
| * rate.</li> |
| * <li>Since any request may use any or all the currently configured |
| * output streams, the sensor and ISP must be configured to support |
| * scaling a single capture to all the streams at the same time. This |
| * means the camera pipeline must be ready to produce the largest |
| * requested output size without any delay. Therefore, the overall |
| * frame rate of a given configured stream set is governed only by the |
| * largest requested stream resolution.</li> |
| * <li>Using more than one output stream in a request does not affect the |
| * frame duration.</li> |
| * <li>Certain format-streams may need to do additional background processing |
| * before data is consumed/produced by that stream. These processors |
| * can run concurrently to the rest of the camera pipeline, but |
| * cannot process more than 1 capture at a time.</li> |
| * </ul> |
| * <p>The necessary information for the application, given the model above, |
| * is provided via the {@link CameraCharacteristics#SCALER_AVAILABLE_MIN_FRAME_DURATIONS android.scaler.availableMinFrameDurations} field. |
| * These are used to determine the maximum frame rate / minimum frame |
| * duration that is possible for a given stream configuration.</p> |
| * <p>Specifically, the application can use the following rules to |
| * determine the minimum frame duration it can request from the camera |
| * device:</p> |
| * <ol> |
| * <li>Let the set of currently configured input/output streams |
| * be called <code>S</code>.</li> |
| * <li>Find the minimum frame durations for each stream in <code>S</code>, by |
| * looking it up in {@link CameraCharacteristics#SCALER_AVAILABLE_MIN_FRAME_DURATIONS android.scaler.availableMinFrameDurations} (with |
| * its respective size/format). Let this set of frame durations be called |
| * <code>F</code>.</li> |
| * <li>For any given request <code>R</code>, the minimum frame duration allowed |
| * for <code>R</code> is the maximum out of all values in <code>F</code>. Let the streams |
| * used in <code>R</code> be called <code>S_r</code>.</li> |
| * </ol> |
| * <p>If none of the streams in <code>S_r</code> have a stall time (listed in |
| * {@link CameraCharacteristics#SCALER_AVAILABLE_STALL_DURATIONS android.scaler.availableStallDurations}), then the frame duration in |
| * <code>F</code> determines the steady state frame rate that the application will |
| * get if it uses <code>R</code> as a repeating request. Let this special kind |
| * of request be called <code>Rsimple</code>.</p> |
| * <p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved |
| * by a single capture of a new request <code>Rstall</code> (which has at least |
| * one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the |
| * same minimum frame duration this will not cause a frame rate loss |
| * if all buffers from the previous <code>Rstall</code> have already been |
| * delivered.</p> |
