摘要： An image processing apparatus includes a first color determining device, a storage device, a second color determining device, an output image processing device, and a controller. The controller compares between a first area of input image data and a second area of the input image data to generate a comparison result. When the comparison result indicates that the second area of the input image data does not match the first area of the input image data, the controller causes the second color determining device to generate the second determination result and causes the output image data to be generated based on the second determination result. When the comparison result indicates that the second area of the input image data matches the first area of the input image data, the controller causes the output image processing device to apply image processing determined based on the first determination result.

摘要： An image processing apparatus and an image processing method for improving the productivity of image reading. Moving speed control processing performed by a control unit causes an image reading portion to move the position of a reading line in a sub-scanning direction of a document, to read an image on the document in the main scanning direction, and to output the image data on the read line. A read image correction portion converts (including primary resolution conversion processing of converting the resolution of the image data in the main scanning direction or sub-scanning direction into a specified resolution) the characteristics of the image data to data characteristics that are predetermined at the time of accumulation of the image data, and accumulates the converted image data in a HDD. Then, an image processing portion converts (including secondary resolution conversion processing of converting the resolution of the image data in the main scanning direction or sub-scanning direction into a specified resolution) the characteristics of the image data accumulated in the HDD into device characteristics of a device to which the image data is output, and outputs the converted image data to an image writing portion or to the device to which the image data is output, via an external I/F control unit.

摘要： An image processing apparatus including an image processing circuit, a frequency dispersion circuit, and a timing signal generator. The image processing circuit processes an image signal, and the frequency dispersion circuit performs frequency dispersion relative to a reference clock signal by continuously modulating an oscillating frequency of the reference clock signal in a predetermined modulation cycle and to generate a frequency dispersion clock signal. The timing signal generator generates a timing signal that controls an operation of the image processing circuit using the frequency dispersion clock signal, in synchronism with the predetermined modulation cycle used for the frequency dispersion.
