Similar to audio processing, the Android Camera Hardware will provide you with image frames when they are ready, but the frames is given in a 1-D array as byte[] data, instead of a 2-D array. Following the YUV format, if we have an image of M x N, the byte[] data array we get will be of length M x N x 1.5, as shown below: Conversion YUV 420_888 to Bitmap (full code) The function takes the media.image as input, and creates three RenderScript allocations based on the y-, u- and v-planes. It follows the YUV_420_888 logic as shown in this Wikipedia illustration.
