Abstract:
An image processing apparatus, comprising:a first sampling clock generator configured to generate Nw first sampling clock signals which respectively have a first frequency that is synchronous with a first synchronizing signal of a given first analog image signal and phases that are sequentially shifted; and an analog-to-digital conversion unit configured to convert the first analog image signal with respect to Nw pixels into Nw digital image signals, the first analog image signal including three analog color components, each of the Nw digital image signals including three digital color components, wherein the analog-to-digital conversion unit comprises three sub-units corresponding to three analog color components, respectively, each sub-unit comprising Nw analog-to-digital converters configured to commonly receive a pre-selected analog color component and to successively carry out analog-to-digital conversion of the received analog color component in response to respective of the Nw first sampling clock signals, so as to generate the Nw digital color components with respect to the Nw pixels, the Nw digital color components having phases sequentially shifted, and the image processing apparatus further comprises a processor configured to simultaneously process the Nw digital color components output from the analog-to-digital conversion unit.
