  • Patent number: 9576341
    Abstract: An image-processing system including an image processor and a correction processor is provided. The imaging processor obtains a captured image. The correction processor produces a corrected image by correcting an aberration that emerges in the captured image. The correction processor produces: at least one or more processed images obtained by applying different processes to the captured image; a masking image by applying a predetermined process to one of the captured images or the at least one or more processed images; a composite image by synthesizing the masking image and either of the captured image or the at least one or more processed images, which are not used when producing the masking image; and the corrected image by synthesizing the composite image and the captured image.

  • Patent number: 9106823
    Abstract: An autofocus device is provided that includes a lens drive system, an imager, a contrast detector, first and second peak detectors, and a backlash detector. The lens drive system translates a lens. The imager captures an image through the lens. The contrast detector detects the contrast of an image captured by the imager. The first peak detector detects a first contrast peak of images captured at different lens positions when the lens is translated in a forward direction. The second peak detector detects a second contrast peak of images captured at different lens positions when the lens is translated in a backward direction. The detection of the second peak is carried out after detection of the first contrast peak. The backlash detector detects the backlash in the lens drive system according to the positions of the first and second contrast peaks.
