We studied a method of simplifying an input process of original image data in the synthesis of holographic stereograms. First, on-frame image of an object was taken using a CCD camera. As the object, a building in the outdoors or a box in a room was was used. Then, the three-dimensional shape of the object was recovered. Rotating a screen around the recovered object. image data of 100 frames were generated. These image data are recorded on a holographic film using a liquid crystal television panel. Object images which might be seen from different angles can be reconstructed as holographic images with laser light illumination.

To clarify the mechanism of information processing in biological system, behavior pattern of animals have been analyzed by using image processing techniques. In conventional method, the behavior pattern was investigated by implanting lightbulb on animal's head. However, this method necessitate operation for the implant. Furthermore, the weight and light emission of lightbulb would have bad effect upon animal behavior. Thus, we developed new experimental system for measuring animal's position by detecting colors painted on animal's body. This method is superior in the following two points. One is that it necessitate no operation, and the other is that it can be extended to analyze various behavior pattern by using some different colors at the same time.

The paper describes how intelligent structure analysis and reproduction of mathematical formulas in scientific and technical document images can be performed by means of the structure rule of formulas. This rule is based on the attribute grammer. Here, we take two kinds of attributes:one is geometrical and the other semantic. The geometrical attribute consists of the character size, center position, subscript/superscript etc., and the semantic attribute includes the font, type and so on. And also we deal with recognition of the character font which is meaningfull in mathematical formulas. After partition of the area of mathematical formulas, each character is segmented and its featurs are extracted. We take the slope and density as features, which are essential and usefull enough to classify a set of English letters with various fonts. As a result, its category and font can be identified with high accuracy and efficiency.

In order to set up a pattern database of ceramics, it is necessary to develop the pattern considering 3 dimensional shape. Then this paper describes the recovery of the solid of revolution from a monocular image unknown camera parameters. The solid of revolution is supposed an old ceramics having a bottom and a mouth. The camera parameters are searched by using genetic aigorithm(GA). From obtained camera parameters, the solid of revolution is recovered. As a results, using a monocular image of an old ceramics digitized by scanner, the solid revolution is recovered.

We propose and discusses a extraction method of human motion information from actual images without any contact devises. The method are composed of bottom-up analysis and top-down analysis based on representative motion patterns. Using the movement information of 3D-D. positions of some human points(head, hand, face) detected from stereo images, the human motion pattern sequence is estimated and predicted, and then human motion is reconstructed using this result. Combining the reconstructed motion and the contour of silhouette image, the movement of the configuration of the model (human) can be estimated from an image sequence.

Three Dimensional Spline Modification System is developed for getting the basic acknowledge of Stereo Vision CAD System, And the characteristic of that system is analized. This system is consisted by 1)EWS for controlling the whole system and making the virtual shape, 2)Liquid Crystal glasses for displaying the 3D Vision, and 3)3D-Mouse for indicating the position & direction or the picking operation. As a result of the practice. We have realized the 3D-Spline generation by the axis-independent scaling method.

History of invention and implementation of CCDs are presented in this paper. We discuss technological problems,such as resolution,sensitivity,cost reduction, fixed pattern noise (defects on reproduction image),smear and value-added features, and introduce the key for success in development and business. Technological trend on linear/area CCD image sensors and an amplifying image sensor for some use,for example,camcoders,production-house/broadcast cameras,HDTV cameras and mulimedia cameras,are mentiond. Moreover,we refer to the technical view and the huge multimedia market in the future in relation to CCDs' applications.

An image sensor for image processing has been developed. A 1/4-inch 250,000 pixel amplified MOS imager has been equipped with three independent outputs. AMI's non-destructive read-out operation and three lines of memory built in the sensor make it possible to output the signals of three independent lines simultaneously. By applying the function, a vertical DTL circuit and an FPN suppression circuit are realized without an external delay-line or memory.

This paper describes the performance of a single layer electrode CCD with a inter-electrode gap width of 0.3,am. Charge Transfer Efficiency(CTE) is investigated in two regions: a small signal charge region and a large signal charge region. A newly found CTE degradation in the large signal charge region, which determines charge handling capability, is analyzed.

An experiment on the progressive scanning of a 2/3-inch 2M-pixel CCD is presented. A reproduced picture with a interlace-scanned CCD suffers from the lack of the vertical resolution, which is caused by the charge mixing between vertically neighboring two pixels and the interlace flicker. We have tried to solve the problem by introducing the progressive scanning. A multiple frame interline transfer CCD (M-FIT CCD) was used in the experiment for the reason of its structure which enables the charges of every each pixel to be handled separately.

Optical system for the ultra-compact CRT projection display with slim set-depth and wide viewing angle has been developed. For reduction of set-depth, a projection lens system consisting of 4 plastic lenses and 1 glass lens is renewed to shorten the projection distance by 20% (in Furthermore, a new aspherical-shaped comparison with our '92 model). Furthermore, a new aspherical-shaped lenticular-lens and surface diffuser are introduced into the screen to widen the viewing angle near to that of direct-view type TVs. Consequently, 39.5cm set-depth and viewing angle approximately 1.5 times as wide as that of conventional model have been achieved in 39" (aspect ratio; 16:9) rear projection TV.
