An endoscope includes: pixels arranged in a matrix form and configured to generate an imaging signal according to an amount of received light, and output the imaging signal through one of vertical lines in the pixels, each two pixels adjacent to one another in a horizontal direction sharing a single vertical line； dummy pixels, each provided for each vertical line in the pixels； a determination unit for determining whether output values of dummy signals having been output multiple times from a dummy pixel of the dummy pixels, are within a range of a threshold； a correction data generator configured to: calculate, for each vertical line, a statistic of the output values of the dummy signals determined to be within the range of the threshold； and generate, for each vertical line, correction data based on the calculation； and a correction unit for correcting the imaging signal based on the correction data.
