Abstract: An image processing apparatus (12) for detecting feature points in inputted images (10, 11) comprising an optical flow detection section (13). The optical flow detection section (13) serves as: a full feature point detection section for detecting as a full feature point a point whose pixel value changes significantly when in whatever direction the pixel is moved; and a semi feature point detection section for detecting as a semi feature point a point whose pixel value hardly changes when the pixel is moved in a certain direction of the image but the pixel value changes significantly when the pixel is moved in other directions. This enables extracting feature points evenly from all portions of the image and enhancing accuracy in alignment when images are synthesized.

Abstract: An image capture device (1) sets a central vicinity of a frame (606) of a predetermined area as a focus region upon detecting a half-press operation of a shutter button (3) in a through-the-lens image displaying, designates a central vicinity pixel region of the region as a pixel region (608) to be tracked, and determines whether or not the designated pixel region is adequate as an object of tracking. If the pixel region is adequate, the pixel region is tracked until the shutter button is detected as pressed down fully. When a fully-press operation of the shutter button is detected, the frame of a predetermined area is displayed in a fixed manner on a display unit (6). Upon a detection that a change of the pixel region has occurred, or the pixel region has contacted or exceeded the frame of a predetermined area, a recording processing is started immediately by a high speed consecutive capture.

Abstract: A television video signal A/D converter apparatus has an A/D converter which samples a television video signal to A/D convert it in accordance with upper and lower reference potentials, and supplies the digital signals to a liquid crystal display device. The apparatus also has detectors which detect digital values of the digital signals from the A/D converter which exceed a predetermined value and are below another predetermined value, and which respectively correspond to the upper and lower reference potentials for A/D conversion by the A/D converter. The digital values exceeding and below the predetermined values are counted by a counter, and the upper and lower reference potentials are determined in accordance with the respective counts and are supplied to the A/D converter.

Abstract: PROBLEM TO BE SOLVED: To provide a picture encoding method and storage medium that selects a picture element sequence on the edge of a block adjacent to a block to be encoded out of a block picture element used for prediction, improves prediction precision by using an average value of the picture element sequence concerned and can improve encoding efficiency. SOLUTION: An input picture is divided into blocks, each block is converted into a DCT coefficient by a two-dimensional DCT transformation and further linear quantified, the DCT coefficient quantified is entropy encoded and made to be code data and, at the same time, decoded and converted to a decoded picture element value, and a local decode block is generated. Then, since blocks 5 and 16 are already completely reconstructed at the time of processing a block 17, it is possible to use an average value of one picture element sequence on the edge part of the blocks 5 and 16 indicated by hatched lines at the time of calculating predicted value, information on a picture element short in distance is reflected upon the predicted value, the precision of prediction is improved and encoding efficiency can be improved.
