  • Patent number: 8953068
    Abstract: An imaging device includes: an image sensor that outputs pixel signals by capturing a subject image, the image sensor including a plurality of pixels disposed in a matrix pattern and; a calculation unit that calculates correction values each used to individually correct errors in pixel signals read out from one of pixel columns at the image sensor, while the image sensor in a continuous shooting state continuously outputs the pixel signals; and a correction unit that corrects the pixel signals by using the correction values calculated in the continuous shooting state, wherein: if a specific condition changes in the continuous shooting state, the correction unit corrects the pixel signals by using the correction values already in use.
    Type: Grant

  • Patent number: 8081229
    Abstract: An imaging apparatus includes: an image sensor having a plurality of pixels arranged in an array that captures an image of a subject and outputs pixel signals; a calculation unit that calculates a correction value for correcting an error of the pixel signals read out 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. In a live view mode, the calculation unit calculates a new correction value by averaging the calculated correction value and a correction value for a previous frame.
