Abstract:
When edge smoothing is applied to a portion where trapping was applied, the two processes are applied to a small region, thus causing image deterioration. Hence, the invention is configured to exclusively set trapping and edge smoothing execution conditions. Then, even when application of both trapping and edge smoothing processes to an entire image is selected, one of these processes is applied to each individual pixel or region. Alternatively, an execution completion flag may be set for one of these processes, and the other process may be executed with reference to that flag.
