IMAGE SIGNAL PROCESSING DEVICE PERFORMING IMAGE SIGNAL PROCESSING THROUGH PLURAL CHANNELS

摘要

An image signal processing device includes a channel converter to divide an input signal stream, that includes image signals generated by a plurality of pixels, by processing units and generate a plurality of processing unit signals, an image signal processing core including a plurality of image processing channels each performing an image signal processing operation, and generating a plurality of output unit signals by receiving and processing the plurality of processing unit signals in parallel through one or more of the plurality of image processing channels, a channel combiner to combine the plurality of output unit signals and generate an output signal stream, and a configuration controller to control, according to an operation mode, at least one of the number of the plurality of processing unit signals, selection of a frequency of a processing clock signal, and combination of the plurality of output unit signals.
