Abstract:
1. An image processing device which includes a plurality of calculation units performing a calculation process on input image data and outputting the image data, changes at least one of a combination of the calculation units forming a pipeline and an order of the calculation units disposed on the pipeline in accordance with setting of an operation mode of image processing, and performs the image processing in accordance with the setting of the operation mode of the image processing, the image processing device comprising: a plurality of clock selection units configured to respectively correspond to the calculation units forming the pipeline and to select a clock signal to be supplied to the corresponding calculation unit from a plurality of input clock signals and output the clock signal; a data delivery unit disposed on the pipeline between the calculation unit to which a first clock signal is input and the calculation unit to which a second clock signal with a frequency different from a frequency of the first clock signal is input and configured to output the image data subjected to the calculation process and output at a timing of one of the first and second clock signals, at a timing of another of the first and second clock signals; and a control unit configured to control a selection of the clock signal by each of the clock selection units, a combination of the data delivery unit and the calculation units forming the pipeline, and an order of the data delivery unit and the calculation units disposed on the pipeline in accordance with the operation mode of the image processing.
