Abstract: An example image processor for processing pixels includes processing circuitry configured to determine that a first subset of input bits of a current pixel are the same as a first subset of input bits of a previously processed pixel, selectively bypass processing the first subset of input bits through a first pipeline based on the determination, output a first subset of output bits of the previously processed pixel as a first subset of output bits of the current pixel based on the determination, and merge the first subset of output bits of the current pixel with a second subset of output bits of the current pixel generated through a second pipeline from a second subset of input bits of the current pixel.

Abstract: Systems and techniques are described herein for processing frames. For example, a process can include obtaining a current frame from a sequence of frames, the current frame associated with a first bit depth resolution and a reference frame preceding the current frame associated with the first bit depth and resolution. The process can include determining a difference between a first pixel value of the current frame and a second pixel value of the reference frame, the first pixel value and the second pixel value associated with a corresponding first pixel position. The process can include outputting a first portion of the determined difference as a first output value and, based on a determination that the determined difference does not exceed a maximum magnitude of a second bit depth, outputting an indication that the determined difference does not include a second portion associated with the first pixel position.
