Abstract: A camera or other optical system is focused by generating a plurality of digital images each obtained with a different focus setting of the optical system. These images are analysed to generate for each image a score (S) by comparing first groups of pixels chosen from the image with second groups chosen from the image such that the pixels of each second group have same respective positional relationships with respect to one another as the pixels of the first group with which it is compared have to one another, the score (S) being a function of the number of matches obtained with said comparisons. The focus setting that gives the score corresponding to the largest number of matches is chosen.

Abstract: Exposed images from a CCD are each captured to Surfaces A, B and C in an SDRAM in a repeated sequence from A, B to C, and the latest image among the images thus captured is displayed. While an image on Surface B is being transferred, an image on Surface A is used as the image to be displayed. The next exposure is started, and images to be displayed are switched, at the same timing as the transfer is started. An image to be displayed on an LCD monitor is stopped from being updated when camera shake compensating device starts to be released from the mechanical holding. The next switching of images and the transfer of an exposed image from the CCD to the SDRAM are prohibited. When the release of the mechanical holding is completed, the next exposed image is transferred from the CCD to the SDARM. Updating is permitted for displaying the image which is transferred to the SDRAM on a display device.

When the moving image being displayed is paused, a still image is displayed based on the frame image data “A” shot using the short exposure time.

Abstract: A wide dynamic range image sensor method combines the response of high-gain sensing cells and low-gain sensing cells with better linearity than the prior art.
