ИСТИНА

An image processor comprises image processing circuitry implementing a plurality of processing layers including a preprocessing layer for received image data and one or more higher processing layers coupled to the preprocessing layer. The image processor further comprises a multi-channel interface including at least first and second image data channels arranged in parallel with one another between the preprocessing layer and a given higher processing layer. The first image data channel is configured to carry partial depth information derived from the received image data to the given higher processing layer, and the second image data channel is configured to carry complete preprocessed frames of the received image data from the preprocessing layer to the given higher processing layer. By way of example only, in a given embodiment the partial depth information comprises depth information determined to have at least a specified level of reliability.
