PURPOSE: To provide a general processing system in which image information can be processed regardless of difference in the format of the image information stored in a display memory, the width of pixel, or the width of a field or the like. CONSTITUTION: When the number of bits of each field in which video image information is stored, that is, the width of the field is a specific number considered to be general, for example, a number less than 8, it is increased to 8, and unified to the general format. At the time of this extension, bit string in the field before extension are repeatedly inserted sequentially in a descending order from the most significant bit position of the extended field so that the difference between the value of the field after extension and the value of the field before extension is less than half the least significant bit of the extended field. |
