ABSTRACT:
An image processing apparatus includes a photoelectric conversion circuit for reading an original image by photoelectric-converting and for outputting an image signal, wherein the photoelectric conversion circuit is a dual channel register type separately outputting the image signal for odd numbered pixels and even numbered pixels; an analog-to-digital conversion circuit for converting the image signal to the image data which includes odd numbered pixel data for the odd numbered pixel and even numbered pixel data for the even numbered pixel; an image separation circuit for generating an odd numbered line data and an even numbered line data from the odd numbered pixel data and the even numbered pixel data, wherein the image separation circuit includes four line memories, and the odd numbered pixel data and the even numbered pixel data are synthesized to the odd numbered line data and an even numbered line data after the odd numbered pixel data and the even numbered pixel data are stored to each of the four line memories; and an outputting device for outputting an image based on the set of the odd numbered line data and the even line data.
