摘要： A system controller controls a solid-state image pickup device so as to read pixels at a predetermined pixel skip-reading-out rate. During pixel skip-reading-out, the system controller adds up, for example, four pixels to acquire a value representative of a unit area for pixel skip-reading-out. A space between adjoining ones of pixels to be added up is set to, for example, a half of an inter-sample space, whereby an MTF of an image signal representing added pixels, which is attained at the sample rate, is set to 0. Consequently, an aliasing noise can be eliminated and deterioration in image quality can be prevented. Moreover, since four pixels are added up irrespective of a pixel skip-reading-out rate, a sensitivity will not vary.

摘要： An image captured with a CCD is divided into blocks. Light amount correction data each set for each one of the blocks are read out from a correction value table 211g, a correction value generator 211h weights the light amount correction data in accordance with the positions of target pixels to thereby generate correction values for the respective target pixels, and image field edge brightness reduction correction is performed on the respective pixels based on the correction values. Since one piece of the data is set for each block, the volume of the data is small. This also prevents boundaries between the blocks from becoming noticeable.

摘要： A system, (i.e., a method, an apparatus, and computer-executable process steps), providing sharpness enhancement for coded video, in which a usefulness metric, calculates how much a pixel can be enhanced without increasing coding artifacts. The usefulness metric is separate from the enhancement algorithm such that a variety of different enhancement algorithms can be used in conjunction with the metric.
