Abstract: A color image processing device includes an input unit, an adjusting amount storage unit, a first conversion unit, a second conversion unit and an adjusting unit. The input unit inputs an adjustment substitute value to be selected for a color adjustment. The adjusting amount storage unit stores an adjusting amount corresponding to the adjustment substitute value for each color space including a first color space and a second color space. The first conversion unit converts the input image data into image data of the first color space. The second conversion unit converts the input image data into image data of the second color space. The adjusting unit adds an adjustment to the image data of the first color space and the second color space by using the adjusting amount for the color space of the converted image data. The adjusting amount is stored in the adjusting amount storage unit by being associated with the input adjustment substitute value.

Abstract: A color image processing device includes an acquiring unit that acquires sample values of an original document at a prescribed cycle from a plurality of line sensors provided in parallel with a main scanning direction at a prescribed interval between one another, a storage unit having a capacity that stores the sample values for a prescribed number of samplings and a transferring unit that transfers relatively the original document and sampling positions of the line sensors. A correction unit corrects by carrying out a gap correction process for correcting a gap of the sampling positions of each of the line sensors in accordance with the sample values stored in the storage unit and an instructing unit instructs the transferring unit. In accordance with a rate of magnification for scanning the original document and the capacity of the storage unit, the instructing unit determines whether the gap correction process according to the rate of magnification can be carried out.

Abstract: A color image processing device includes a pre-correction unit, a computation processing unit and a post-correction unit. The pre-correction unit includes a pre-correction circuit which carries out a pre-correction to reverse a highest-order bit of a pixel value on input data of a color component. The pre-correction unit selectively outputs the input data of the color component or the data of the color component pre-corrected by the pre-correction circuit according to the color component. The computation processing unit carries out a prescribed computation processing on the data of the color component output by the pre-correction unit and outputs the data of the color component carried out with the prescribed computation processing. The post-correction unit includes a post-correction circuit which carries out a post-correction to reverse a highest-order bit of a pixel value on the data of the color component output by the computation processing unit.
