Abstract:
1. An electronic camera, comprising: an image sensor having pixel columns and a charge transfer unit that transfers an electric charge for each of the pixel columns; a correction unit that obtains a leakage charge signal for each of the pixel columns and corrects an electric charge signal outputted from the charge transfer unit by subtracting an amount, resulting from multiplying a value of the leakage charge signal by a correction coefficient, from a value of the electric signal; a control unit that controls the correction unit; and an actuation member that generates a first signal that commands a start of photography using the image sensor, and a second signal before the start of photography is commanded, wherein the control unit controls the correction unit to use a first correction coefficient before the second signal is generated and to use a second correction coefficient different from the first correction coefficient after the second signal is generated, when multiplying the value of the leakage charge signal.
