IMAGE PROCESSING APPARATUS COMPENSATING FOR DISTANCE BETWEEN DOCUMENT PORTIONS READ BY RESPECTIVE SENSORS

An image processing apparatus having a plurality of parallel linear sensors, which may be sensors for different colors, in which output from one or more of the sensors may be subjected to an interpolation process to produce image data corresponding to the same scan line of an original as the image data being output from another of the sensors. This makes it possible to use the same driving signals for all the sensors even if they are staggered, and yet to produce output image data free of noise of the kind which can be caused by crosstalk. In one embodiment, compensation is made for a distance between two (or more) of the image sensors, based on magnification. In another embodiment, an interpolator is provided and interpolates an image signal of two adjacent lines of image from one image sensor, in accordance with magnification, to obtain an image signal on the same line as that from another of the image sensors.
