Abstract: A video signal, replay by a video player, is subjected to image processing by a calculation control part of a video image searching device to calculate the image quality value and another feature value. An image whose image quality satisfies a predetermined condition and whose feature value matches a predetermined condition is detected as an image in which an event has occurred. Such images are printed on an output paper together with associated addition information. A main control part of a video image access device reads out the additional information on the output paper by a scanner and effects control via a video control part to search the image corresponding to that information by a video player.

Abstract: Image information units, related with one another in the order of their magnitudes defined for each of a plurality of properties of each image, are prestored in an image information storage and management device. All image information units adjoiningly related by their properties with a main image being displayed on a display are read out of the image information storage and management device, and contracted images of the read-out image information units are displayed as navigators on the display screen, together with the main image.

Abstract: A difference vector indicating movement of a pen between two adjacent sampled points is divided into macro movement and micro movement components. The macro and micro components are coded independently of each other so as to provide effective coding. In the case of coding the difference vector, the magnitude of the difference vector is coded in accordance with the types of zones (zone number k) and relative pel address within the zone. In order to improve the coding efficiency, a zone number difference is used instead of the zone number. Furthermore, the direction of the difference vector is expressed by a quadrant which includes this difference vector. In order to further improve the coding efficiency, a quadrant number difference is used instead of the quadrant number.

Abstract: A structure and a method for manufacturing a contact disk for detection of angular position and direction includes a concentrically-arranged planar slip-ring like conductive layer at the innermost region of the disk, a first gear-pattern like conductive layer, having outer teeth, at its midway region, and a second gear-pattern conductive layer, having internal teeth at the outermost region of the disk, all formed on an insulative substrate; the gear-pattern conductive layers are both printed at the same time to insure high accuracy in the position of the conductive layers; crossing parts of the lead connections are printed with the use of an insulative film therebetween.

Abstract: A color picture is separated into three color component pictures, which are divided respectively by first, second and third block coding means into blocks and encoded. In the first block coding means, one of the color component pictures is encoded, for each block, into gray level codes representing gray level components in the block and a resolution code representing the distribution of the gray level codes in the block. In this case, when the gray level in the block undergoes a little change, an average gray level can be used as the gray level code and the resolution code can be omitted. The second and third block coding means may be identical in construction with the first block coding means. The resolution code of the block obtained by the first block coding means can also be employed in the coding of the corresponding blocks by the second and third block coding means.

Abstract: The input surface of the apparatus for detecting X and Y coordinates of the input points comprises a first parallel electrode group, a second flexible parallel electrode group opposing and intersecting the first parallel electrode group. A pressure conductive rubber sheet which becomes conductive when the pressure is applied to the input surface is interposed between the two electrode groups. First and second resistors are provided which are in electrical contact with terminal ends of the two electrode groups. Electric signals from the first and second resistors are used to detect X and Y coordinates of input points on the input surface.

Abstract: A frame of a gray-scaled picture is divided into blocks, in each of which the mean luminance of picture elements is used as a threshold value for comparison with each picture element signal to classify it into 0 or 1 according to its magnitude to provide a resolution component. From the resolution component and each picture element signal in the block are calculated two gray components; the resolution component and the two gray components are used as coded outputs for each block.

The size of each block is changed in accordance with the property of the picture in the portion corresponding to the block.
