摘要： Method for detecting a focus condition of an imaging optical system by using a surface acoustic wave device is disclosed. A light receiving element array formed by a plurality of light receiving elements receives a light flux transmitted through at least a part of an image formed by the imaging optical system. Then, outputs of said light receiving elements are processed on real time by means of a Fourier transform device including a surface acoustic wave device, a convolver, etc. so as to derive an image sharpness and/or an image lateral shift, both of which are used for a focus detection. Therefore, as compared with a conventional focus detection method, it is possible to perform the focus detection in a fast and accurate manner by a simple and small construction.

摘要： In an electronic still camera system for forming one still frame image by synthesizing odd and even field images which are field-sequentially output from a CCD, an image compensation circuit is arranged to prevent a deterioration in quality of a still frame image due to an image shift between the two field images. The image compensation circuit includes an interpolation circuit for obtaining two pseudo frame images by performing field interpolation of the odd and even field images, a correlation arithmetic circuit for detecting an amount of image shift between the two field images on the basis of the correlation between the two pseudo frame images, and a shift compensation circuit for compensating the image shift by shifting one of the two field images in accordance with the detected amount of image shift. The correlation arithmetic circuit divides each field image into a plurality of blocks, and detects an amount of image shift in units of blocks. The shift compensation circuit shifts an image in units of blocks.
