Publication number: 20090147108Abstract: A CCD solid-state image sensor alternately outputs, pixel by pixel, N (where N is an integer of 2 or more) lines of image signal and a line of smear signal for correcting the N lines of image signal by switching an output line from one to another. an AD conversion section performs an AD conversion on the output signal from the CCD solid-state image sensor. A smear data separation section separates smear data from the sensor output data output from the AD conversion section and converts the separated smear data to corrective smear data corresponding to each image data. A subtraction circuit performs a smear correction by subtracting, from each image data, the corrective smear data corresponding to the image data. Smear correction is appropriately performed even if a high-brightness object moves.Type: ApplicationFiled: December 5, 2008Publication date: June 11, 2009Inventors: Yoshinori Okura, Yukihiro Tanizoe, Tomoharu Miyake
