Image processing device

Abstract

Abstract PURPOSE: To allow the processing unit to self-diagnose whether or not a printed circuit board for image processing is normal by detecting a defect of the printed circuit board for image processing from a content of image data sampled by a sampling means. CONSTITUTION: A main printed circuit board (image processing printed circuit board) 100 is provided with a 3-line CCD (charge coupling devices) 101 separating colors of a reflected light from an original and converting the light into an electric signal, with a shading correction section (signal generating means) 103 correcting the sensitivity of each pixel of the CCD 101 to correct a tilt in the luminous quantity of a light source and to generate a test pattern signal, a sampling means sampling the image signal generated by the signal generating means 103 and with a detection means detecting a defect of the main printed circuit board (image processing printed circuit board) 100 based on the content of the image data sampled by the sampling means. Thus, the test pattern image signal is sampled and then the defect of the main printed circuit board (image processing printed circuit board) 100 is detected based on the content of image data.
