Abstract
An optical detection device comprising an optical sensing section that has an optical detection transistor, a threshold voltage detecting section that has a threshold value detection transistor, a sensor output value generating section that generates a sensor output value on the basis of a signal outputted from the optical sensing section, a correction coefficient determining section that determines a correction coefficient that is used for correcting a change in the sensor output value that corresponds to a threshold voltage detected at the threshold voltage section, and a correction processing section that corrects the sensor output value on the basis of the correction coefficient.
