Photoelectric conversion device, image forming apparatus, photoelectric conversion method, and non-transitory recording medium

A photoelectric conversion method executed by circuitry of a photoelectric conversion device having a plurality of photoelectric conversion pixels, the photoelectric conversion method comprising:

• generating image data for each of a plurality of colors based on light received in the plurality of photoelectric conversion pixels;
• detecting, in the plurality of photoelectric conversion pixels, a defective pixel outputting an electrical signal at an abnormal level;
• storing position information of the defective pixel;
• determining, after detecting the defective pixel and by the circuitry automatically executing an algorithm to analyze respective pixel values of peripheral pixels peripheral to the defective pixel, whether or not to perform an interpolation process on the defective pixel;
• and
• performing the interpolation process on the defective pixel when the determining, by executing the algorithm, to perform the interpolation process on the defective pixel, the interpolation process approximating the electrical signal of the defective pixel to an electrical signal at a normal level, and not performing the interpolation process on the defective pixel when determining, by executing the algorithm, not to perform the interpolation process.
