The coder component can dynamically allocate initial subsets of bits for respective coding units of the raw video frame based on residual data identified from the initial motion estimation.

The distance information correcting processor replaces distance information of a target area, where the sum of outline components is less than a threshold value, with distance information of the image with the maximum sum.
