PROBLEM TO BE SOLVED: To reduce a cost on an apparatus by decreasing a memory necessary for storage of trimming data by a method wherein a display means of an image data in a bit area of a binary data, and a means wherein the image data outside the bit area is made to be undisplayable are provided. SOLUTION: A display means of an image data in a bit area of a binary data, and a means wherein the image data outside the bit area is made undisplayable, are provided. For control of an address of an image memory 2, a write counter 12 and a read counter 13 are provided, and an address of an output of each counter is determined with a switching signal (write/read) inputted to a multiplexer circuit 11. A ROM 14 is dedicated memory wherein a trimming data is stored with a binary data. A position for starting synthesis of the image is detected by comparing an image synthesis start position output inputted to one side of a comparator 15 with an output of the read counter 13 of the image memory 2. |
