Abstract:
A scanning line number converting apparatus comprising:input image data storing means for inputting 2-dimensional image data and arranging and storing said inputted 2-dimensional image data in correspondence to each pixel in a line direction;a first processor comprising first temporary storing means for inputting the image data arranged in correspondence to the pixels in the line direction by said input image data storing means and for temporarily storing the image data of a plurality of lines and first arithmetic operation processing means for performing an arithmetic operating process to the image data stored in said first temporary storing means;first control means for giving a control command to said first processor;a second processor comprising second temporary storing means for inputting the image data from said first processor and for temporarily storing the image data of a plurality of lines and second arithmetic operation processing means for performing an arithmetic operating process to the image data stored in said second temporary storing means;second control means for giving a control command to said second processor; andoutput line data storing means to which the image data from said second processor is transferred every line and which arranges and stores and sequentially outputs said image data in correspondence to the pixels in the line direction,wherein said first and second processors have a construction such that each column constructs element processors and a common command is given to each of said columns by said first and second control means,said first temporary storing means of said first processor is allowed to function as a first-in first-out register to temporarily store the image data of a plurality of lines,said second processor generates a transfer request signal and sends said transfer request signal to said first processor,said first processor transfers the image data to said second processor in response to said transfer request signal, anda predetermined interpolation arithmetic operating process is performed in said second processor, thereby performing a scanning line number conversion.
