Controlled image deterioration correction device with reduction/enlargement
An image processing device for processing input image data includes a correction unit that corrects for image deterioration caused by changes in image magnification; a reduction/enlargement unit that, based on the magnification, thins out the pixel data when reduction is being performed or carries out inflation of the pixel data when enlargement is being performed; and a controller that changes the operation of the correction unit in response to the magnification. The image processing device further includes a first selector that sends input pixel data to the reduction/enlargement unit when enlargement is being performed, and sends pixel data from the correction unit to the reduction/enlargement unit when reduction is being performed; a second selector that sends pixel data from the reduction/enlargement unit to the correction unit when enlargement is being performed, and sends input pixel data to the correction unit when reduction is being performed; and a third selector that outputs pixel data from the correction unit when enlargement is being performed, and outputs pixel data from the reduction/enlargement unit when reduction is being performed.
