Abstract
An apparatus for processing image data. The apparatus converts analog green image data signals, analog red image data signals, and analog blue image data signals generated by imaging an object. The third image generation elements, representing the green image data, are arranged at positions shifted by a half pitch to the first and second image generation elements. The analog image data signals are converted into digital image data signals and are then compressed at a predetermined compression rate and stored in a recording medium by a storage means. In reproducing the image data, the recorded image data is read from the recording medium and expanded at a predetermined expansion rate to generate data substantially the same as the image data signals before compression. The expanded data is interpolated in a predetermined interpolation manner.
