Abstract
A test chart on which measurement images are formed is conveyed in one direction. When the measurement images pass a color sensor, they undergo pre-scanning. A color sensor accumulation time is determined for each measurement image according to the pre-scanning. The test chart is subsequently conveyed in the one direction, whereupon the conveyance direction is changed. In this way, after the color sensor has completed pre-scanning for all of the measurement images, the test chart is once again conveyed toward the color sensor. When the test chart passes the color sensor again, main scanning of the measurement images is executed.
