发明名称 Color signal processing apparatus with a signal interpolation function for use in a color copier
摘要 In a color picture reproducing apparatus, a color light receiving element array has light receiving element which are arrayed in one line and have color separation filters. At least three light receiving elements are assigned for each pixel. The apparatus picks up color signals for each pixel, and reproduces a color picture for each pixel using these picked up color signals. The color signals, which are derived from the pixels of the array on which a portion of a color picture, such as an edge of a black character picture is imaged, inevitably contain errors arising from positional differences between the light receiving elements in one pixel. The errors deteriorate the quality of a reproduced picture. To prevent this, a color signal processing circuit is arranged to interpolate the color signals from adjacent pixels according to the positions of the light receiving elements in one pixel. A signal interpolating circuit for the signal interpolation may separately be provided. Alternatively, a color signal converting circuit may be arranged to perform the signal interpolating function.
