Abstract
An interpolation arithmetic method and an image reader are provided which, in reading a film image using an area CCD sensor in which reading elements are arranged in a hound's tooth check form, is capable of making full use of excellent characteristics of the area CCD sensor. The interpolation arithmetic method and the image reader can be realized by interpolating first image signals of the neighboring two or more reading elements to allocate the second image signals and outputting the interpolated second image signals or the first and second image signals in a square check form, and by providing a light source section; an area image sensor; an imaging optical system; and at least one of pixel shifting device of the area image sensor, and an interpolation arithmetic section for rearranging the second image signals of pixels in the square check form by performing interpolation arithmetic of first image signals outputted from respective reading elements of the area image sensor.
