ABSTRACT:
When a picture with a frame defining an image edition area on a document is read, a carriage including an exposure lamp is moved two times toward a fixed scale, from a stand-by position. With the movement in the same direction, two filters, first and second filters are switched from one to the other. The image data included in light passing through the switched filter is read by a CCD line sensor. A color of the first filter is different from that of the frame on the document. A color of the second filter is same as that of the frame. The image data read through the first filter by the CCD line sensor is stored into a first memory. The image data read through the second filter is stored into a second memory in the same order as that when the image data is stored into the first memory. A control unit properly processes the image data stored in the same orders, to obtain the image edition area.
