Image capturing apparatus

摘要

Position information of a defect in a charge transfer line in an image capturing sensor, which causes a V-line blemish in an image is stored in a blemish information memory. A normal transfer is performed on signal charges in a defective portion in the signal charges corresponding to all of pixels of the image capturing sensor, and signal charges that are not related to the defective portion are transferred at high speed and discharged, thereby reading signal charges for detecting the level of a V-line blemish.
