The apparatus includes a color space conversion portion 110 for converting input image data D1 into data D1s of a standard color space and a reproduction range decision portion 111 for deciding whether the input image data D1s that were converted into the standard color space are within a reference range of a color reproduction in an image output. If it is decided that the input image data are out of the reference range, the calibration is performed so that the color reproduction range is made close to the reference range.

摘要： An image reading apparatus is provided which is capable of correctly reproducing a read image, by correcting variation in read data derived from variation in light intensity and variation in sensitivity, using reading means capable of logarithmic conversion such as an LOG CCD. As variation in read data caused by insufficient light intensity in a shade region of an original is corrected, even when there is a shade in an original image having halftone gradation, satisfactory image reproduction is possible. Since variation in read data caused by insufficient light intensity at the time of zooming is corrected, image quality is not degraded even when electrical zooming is performed. Further, variation in read data caused by fluctuation in light intensity, variation in photosensitivity and types of original is corrected, AD conversion with uniform resolution is possible even when output levels differ because of light distribution variation of a light source or variation in sensitivity of sensors.
