Abstract:
An image processing apparatus including a Y/C separating section for separating an input color image signal into a luminance signal (Y) and a color signal (C), a digital converting section for sampling said luminance signal and said color signal input from said Y/C separating section to thereby convert said luminance signal and said color signal to corresponding pixel-by-pixel digital data, a decoding section for time-division sampling said digital data input from said digital converting section and respectively representative of said luminance signal and said color signal to thereby decode said digital data, a memory having a memory area defining a plurality of block areas for storing said digital data decoded and output from said decoding section, and a memory control section for controlling said memory to write and read out the digital data in and from said memory, said image processing apparatus comprising:a data dividing section for dividing the digital data into a plurality of blocks of digital data and causing the memory control section to write each of said plurality of blocks of digital data in one of the plurality of block areas of the memory; a first parallel shift control section for controlling, block by block, a first parallel shift for shifting said plurality of blocks of digital data to positions coinciding with an angle of rotation of an image; and a second parallel shift control section for subdividing each of said plurality of blocks of digital data into a plurality of subblocks of digital data, and controlling a second shift for shifting the digital data of each of said plurality of subblocks to positions coinciding with the angle of rotation of the image such that a color image is correctly displayed.
