| 16 | Smart Camera / Auto Snapshot (formerly named SimpleCamera) ReadMe |
| 17 | |
| 18 | Created by: Benjamin W Hendricks |
| 19 | |
| 20 | How to build the application: |
| 21 | From root: make SmartCamera will build the apk for generic |
| 22 | Otherwise, to build the application for a specific device, lunch to that device |
| 23 | and then run mm while in the SimpleCamera directory. |
| 24 | Then take the given Install path (out/target/.../SmartCamera.apk) |
| 25 | and run adb install out/target/.../SmartCamera.apk. The application should |
| 26 | then appear in the launcher of your device. |
| 27 | You might also need to run adb sync after building to sync the |
| 28 | libsmartcamera_jni library |
| 29 | Summarized: |
| 30 | make SmartCamera |
| 31 | adb remount |
| 32 | adb sync |
| 33 | adb install -r $ANDROID_PRODUCT_OUT/data/app/SmartCamera.apk |
| 34 | |
| 35 | How to run the application: |
| 36 | On a Nexus 7, open up the application from the launcher, and the camera preview |
| 37 | should appear. From there, you can go to the gallery with the gallery button or |
| 38 | press start to start capturing images. You can also change the number of images |
| 39 | to be captured by changing the number on the spinner (between 1-10). |
| 40 | |
| 41 | What does it do: |
| 42 | The application tries to take good pictures for you automatically when in the |
| 43 | start mode. On stop, the application will capture whatever images are in the |
| 44 | bottom preview and save them to the Gallery. It does this by looking at the |
| 45 | following image features: |
| 46 | - Sharpness |
| 47 | - Brightness |
| 48 | - Motion of the device |
| 49 | - Colorfulness |
| 50 | - Contrast |
| 51 | - Exposure (over/under) |
| 52 | |
| 53 | By comparing each of these features frame by frame, a score is calculated to |
| 54 | determine whether an image is better or worse than the previous few frames, |
| 55 | and from that score I can determine the great images from the bad ones. |
| 56 | |
| 57 | What libraries does it use: |
| 58 | - Mobile Filter Framework (MFF) |
| 59 | - Camera2 API |
| 60 | - Renderscript |
