IMAGE CAPTURE DEVICE AND IMAGE PROCESSING METHOD

摘要

A first restoration processing section 110 and a second restoration processing section 120 perform restoration processing on images (luminance data Y), which are successively captured by an image capture section, using a first filter 102, which is a restoration filter generated corresponding to a point spread function of an optical system, and a second filter 104 of which a restoration strength is weaker than that of the first filter 102. Depending on a result of determination which is input from an in-focus determination section 150 and indicates whether or not the image at the current time point is in a target in-focus state, a selection section 122 selects and outputs either luminance data YA which is processed using the first filter 102 or luminance data YB which is processed using the second filter 104.

主权项

1. An image capture device comprising:
an image capture section that successively captures images; an auto focus adjustment section that automatically performs focus adjustment on the images which are successively captured by the image capture section; a first filter acquisition section that acquires a first filter as a restoration filter which is generated corresponding to a point spread function of an optical system of the image capture section; a second filter acquisition section that acquires a second filter which is a zero phase filter and is applied to a defocused image of the images successively captured by the image capture section and of which a restoration strength is weaker than a restoration strength of the first filter; an in-focus determination section that determines whether or not a processing target image of the images successively captured by the image capture section is in a target in-focus state, due to the focus adjustment performed by the auto focus adjustment section; and a restoration processing section that performs restoration processing, which uses at least the second filter acquired by the second filter acquisition section, on the processing target image in case where the in-focus determination section determines that the processing target image is not in the target in-focus state, and performs restoration processing which uses the first filter acquired by the first filter acquisition section, on the processing target image in case where the in-focus determination section determines that the processing target image is in the target in-focus state.
