PURPOSE:To execute a filter processing such as smoothing or sharpening of an image. etc., without performing a process such as the one to store data in a memory by inputting the data of the image in picture element unit by a sensor arranged in two-dimensional shape, and evaluating and working the sensor output of a specific picture element part with the sensor output of the picture element part in the periphery of a specific picture element outputted simultaneously. CONSTITUTION:A reflected beam of light from an original D forms the image on a CCD sensor S via an image-forming lens L. The information of the original corresponding to an adjacent area of slit shape is outputted from each picture element string of the CCD sensor S. At a reading optical system, the information of three lines of an ongoing line sensor can be inputted in a single action simultaneously at three picture element strings (a), (b), and (c). Therefore, the information of the picture element of the string (b) that is a center can be worked by using the information of the strings (a) and (c) in matrix unit of (3X3). At this time, since the information of three picture element strings can be inputted simultaneously, it is not required to work the output of the line sensor after storing in the memory once as in an on- going system, thereby, circuit configuration for the filter processing can be simplified. |
