ABSTRACT:
A image edit apparatus in which area data of 16-bit width have been stored at the memory locations of the corresponding addresses of the respective memory planes of a plane memory 403. The operation of reading area data therefrom by a pseudo sync signal starts before a line sync signal becomes active. A density-conversion/area generating circuit 405 converts the data format from the plane type to the pixel type, so that area commands are generated. Then, the circuit 405 reads an edit command out of a logic RAM, using the area command as address, and outputs the command. By reading the area data earlier and processing that data, a delay in the density-conversion/area generating circuit can be absorbed, so that the output edit command is synchronized with the image data.
