PURPOSE:To easily convert a picture data at a specific area or a specific color into a picture data of a designated color by storing picture data into a buffer memory, converting the data of the specific area into clear code data and using a lookup table so as to convert it. CONSTITUTION:A clear code 00H is inserted when a picture data is a negative data and a clear code FFH is inserted when the data is a positive data. The point sequential data of R, G, B inputted to a line buffer 28 is replaced into data whose address relating to a range of the specific area designated by an input means 44 is 00H or FFH. A color code data subjected to clear code processing is led to a lookup table 32 converting a color code data into a digital data for driving LEDs 42C, 42M and 42Y. A photosensitive material F exposed is subject to the development processing (not shown) and a picture whose specific area is subject to white color conversion is reproduced. |
