<p>PURPOSE:To obtain a rotation image of high quality free from distortion by dividing a dot data into small areas with an optional size, and while transmitting an error between an oblique axis on a divided point and a shifted variable to the succeeding small area, rotating each small area by using a means group. CONSTITUTION:The title system is provided with an address control mechanism 1 for dividing an image on the way of conversion into small areas so as to store them in an intermediate result memory 9 with specified capacity and a register 2 for transmitting an error between the real oblique axis on a divided point and a shifted variable to an adjacent area to successively rotate image data in each area. Since the image rotation can be attained by the work memory with small capacity without deteriorating the image quality, the image data of a large screen can be rotated without increasing the size and price of the device.</p> |
