Image contracting and display device
专利汇可以提供Image contracting and display device专利检索，专利查询，专利分析的服务。并且PURPOSE: To display a contracted image by thinning the dots of image information stored in a frame memory by a converter and outputting the thinned information without storing it in the memory.
CONSTITUTION: A contracted pattern generator 9 in the converter sets up a picture element position extracted from image information to '1' in accordance with a contraction scale and generates contracted patterns P
0 to P
n consisting of n bits of a contracted unit. A pattern shifting part 10 stores the patterns P
0 to P
n in an FF, selects one of initializing and shifting operation from the FF based on shifted values SIFT
1 to SIFT
n and a clock CLK and generates contracted patterns MP
1 to MP
n indicating the number of thinned dots. A shifted value detecting part 11 executes logical operation based upon the patterns MP
1 to MP
n and detects the shifted values SIFT
1 to SIFT
n for thinning. An image information shifting part 12 also executes the thinning processing of image dots similarly in accordance with the shifting values. In said constitution, the information FD
0 to FD
n of a frame memory can be contracted and displayed without passing them through a video memory.
