About PhotoCoco

PhotoCoco, a camera phone app, utilizes a motion detection system that separates camera and object motion using computer vision. Camera motion can be corrected for, maybe due to a shaky hand at high zoom levels, by shifting the frame to maintain a “steady perspective.” The number of pictures taken depends on thresholds for object detection and motion blur. An artificial control system is used to automatically tune these thresholds in real-time to take an average of 1 photo per N seconds.

There are benefits to using PhotoCoco over the regular camera phone app. In addition to being able to take photos normally, by pressing the Trigger button located on the UI, the app has an option to take photos at regular intervals. The app guarantees that a picture will not be taken while the camera is focusing. The camera can zoom much farther than the regular camera app. The regular camera app limits the zoom capability of the camera, PhotoCoco does not. PhotoCoco can create clear, stop-frame videos from the captured photos.
