Patent ID: 8081229

Claim:
An imaging apparatus comprising: an image sensor having a plurality of pixels arranged in an array that captures an image of a subject, each of the pixels outputting noise signal and image signal including the noise signal:, a calculation unit that calculates a correction value by using the noise signals, the correction value being for correcting an error of the image signals output from the image sensor for each column of the array of the pixels; and a correction unit that corrects the image signals using the correction value calculated by the calculation unit, wherein: in a live view mode in which a plurality of frames of the images corresponding to the image signals are continuously displayed on a display, the pixels output the noise signals and subsequently output the image signals for each frame, the calculation unit calculates the correction value for each frame and calculates an averaged correction value for a current frame, the averaged correction value being calculated by averaging the current correction value for the current frame and the previous averaged correction value for a previous frame, and the correction unit corrects the image signals for the current frame by using the averaged correction value for the current frame.
