Title: Image processor
Inventor: INOUE MOTOICHIRO
IPC: H04N1/41
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain an image processor capable of speeding compressing image data only with simple processing by storing the image data without eliminating it when finite difference is prescribed value or above as the result detected by an adjacent difference detecting means and storing the image data while eliminating it when the difference is the prescribed value of below. SOLUTION: About image data that is blocked to a prescribed unit, first, the finite difference of adjacent data is detected with difference detection. Whether or not the value is below a fixed reference is checked. Since it is decided that information quantity is a little when the difference is the fixed value or below the image data can be eliminated. Since it is decided that information quantity is much when the difference is a fixed value or above, the image data can not be eliminated. That is, when it is below a fixed reference, only representative value of the block is stored in a memory. When it is fixed reference or more, the block does not undergo anything and is stored in the memory as a normal value. Thus, the entire compressibility is improved and processing can be performed at a high speed.
