Abstract

PURPOSE:To store picture information in a memory with less capacity by detecting the extent of the inclination of a scanning line to a picture, controlling a write address according to the extent, and writing information in the memory with the inclination corrected. CONSTITUTION:When a picture is transduced photoelectrically by a scanning system and stored in a memory, the extent of the inclination of a scanning line to the picture is detected to control the address of writing to the memory according to the extent of inclination, and after the inclination is corrected, the data is written in the memory. When a picture A' slants, for example, at an angle theta to main and sub-scan ning directions X and Y, pieces of information DELTAX//sintheta and DELTAY//sintheta are set in registers X1 and Y1. Then, the address is corrected through presettable subtraction counters X2 and Y2, addition-subtraction counters X3 and Y3, and adders X4 and Y4 to write the picture information in the memory M.
