Patent ID: 8842304

Claim:
An image processing apparatus including a reading unit configured to read a document and an image forming and outputting unit configured to perform an image forming and outputting process, the image processing apparatus comprising: a read image transfer circuit configured to process read image information that has been read and generated by the reading unit and configured to transfer the read image information, so as to input the read image information to a controller configured to control the image processing apparatus; an output image transfer circuit configured to process output image information that has been transferred from the controller and configured to transfer the output image information, so as to input the output image information to the image forming and outputting unit, wherein the image forming and outputting unit is to apply the image forming and outputting process to the output image information; and a clock oscillator configured to generate first clocks to be supplied to the read image transfer circuit and second clocks to be supplied to the output image transfer circuit, wherein the clock oscillator is configured to individually alter a first clock supply state for supplying the first clocks to the read image transfer circuit and a second clock supply state for supplying the second clocks to the output image transfer circuit, depending on an operating mode of the image processing apparatus.
