Abstract:
1. An electronic blurring correction apparatus to correct blurring of an image formed on an image-capturing area of a solid-state image-capturing device having a plurality of pixels arranged in a matrix form, to generate an image in which blurring is corrected, the electronic blurring correction apparatus comprising: an image-capturing optical system to form an image on the image-capturing area of the solid-state image-capturing device; a blurring detection portion which detects blurring of the image; an exposure amount control portion which controls the exposure amount of the solid-state image-capturing device; an image-capturing portion which captures a plurality of images with a predetermined exposure amount by means of the solid-state image-capturing device on the basis of control performed by the exposure amount control portion; a first transfer register which stores a first image captured at a first time by the image-capturing portion and transfers the first image in a first direction; a second transfer register which stores a second image captured at a second time, which is different from the first time at which the first image was captured, and transfers the second image in a second direction perpendicular to the first direction; an addition portion which adds up the first image and the second image after relatively shifting the first image and the second image in the first transfer register and the second transfer register respectively, and stores the added images in the first transfer register or the second transfer register; and a readout portion which reads out charges of pixels added up by the addition portion, from the solid-state image-capturing device.
