PROBLEM TO BE SOLVED: To attain the fast rotation, enlargement and reduction and clipping of an image by means of a memory of small capacity with no use of a page memory and with no redundant reading operations required. SOLUTION: A band data storing means 40 reads in sequence the input images, and the local data stored in the means 40 are sequentially read out to undergo the conversion processing such as the rotation and enlargement/ reduction via a local data conversion part 50 and then stored in an intermediate buffer of a converted data storing means 60. Then the local data are read out of the means 60 in their outputting order, stored temporarily in a band buffer of a band data storing means 70 and outputted via an image output means 80. |
