Patent Searching and Data


Title:
An imaging device, an exposure controlling method, and a program
Document Type and Number:
Japanese Patent JP6070283
Kind Code:
B2
Abstract:
An image capturing apparatus includes an image capturing module and a controller that controls exposure of the image capturing module by dividing a captured image by the image capturing module into a plurality of image areas, weighting brightness of a predetermined pixel in each of the image areas, and being based on the weighted brightness of the predetermined pixel in each image area. The controller performs a weighting correction process that increases weighting to the brightness of the predetermined pixel in each image area when the size of the image area after a correction process in which distortion aberration of the captured image is corrected is larger than the size of the before-corrected image area, and decreases the weighting to the brightness of the predetermined pixel in each image area when the size of the after-corrected image area is smaller than the size of the before-corrected image area.
