Title:
PICTURE PROCESSOR
Document Type and Number:
Japanese Patent JPS62144282
Kind Code:
A
Abstract:
PURPOSE:To eliminate the need for a large capacity image memory, to cut down the cost of a device and to shorten the processing time by calculating the length of a picture element comprising an original picture from a compression code and multiplying it by a reduction ratio so as to generate a reduced picture. CONSTITUTION:A processor 1 reads out the compression code out of a code memory 2, judges whether it is the top of a line or not. If so, the processor 1 judges whether the entire line is finished. If not, the processor 1 judges whether the line concerned is thinned or not. If the line is not the top, or not thinned, the length of the picture element is calculated, and multiplied by the prescribed reduction ratio. Then the picture reduced from said length of the picture element is generated in a display memory 4. Each processing is executed by the 1st and 2nd arithmetic means 1a and 1b and a reduced picture generation means 1c.
