摘要： PROBLEM TO BE SOLVED: To provide video follow-up type fast forward reproducing method and device capable of viewing with an audio easy to listen in synchronism with a video when a video recording video, etc., is fast forward reproduced. SOLUTION: First of all, time information is added to the video and audio information to be stored in a storage 1. Then, when the audio is fast forward reproduced, the sound sections of the audio information are decided by a sound section decider 3. A controller 2 connects these sound sections to each other, and instructs an audio converter 4 so as to reproduce the audio data in the storage 1 at a prescribed fast forward reproducing speed. In the reproduction of the audio, an octave converter 5 converts an octave of a regenerative audio of the audio converter 4 in proportion to a reciprocal of a regenerative magnification instructed by the control means 2 to make it the regular audio easy to listen. Further, the reproduction of the video is performed by a video converter 7 by deciding the frame of the video based on the time information of the audio while reproducing simultaneously with the reproduction of the audio.

摘要： PURPOSE:To make an automatic division of a shot by detecting a plurarity of cut points based on a plurarity of division references in editing video. CONSTITUTION:A video source 11 is reproduced by a reproducing/recording device 12A and displayed on a display device 15. An operator 17 makes an input from an input unit 16 and gives an index at an index supply section 13B. At the time of editing, a shot automatic division processing section 13A makes a choice from among a plurarity of cut points divided based on the given references to be displayed on a display device 15B. When simple directions changing the shot length to 'long' and to 'short' are supplied from an input unit 16, another cut point is displayed on the display device 15B. By repeating such processing, the video editing can be performed.

摘要： PURPOSE:To prevent an object except a mobile object having less resistance to a noise from being extracted by obtaining a velocity vector concerning respective small areas of a frame image, obtaining a distribution diagram, removing the distribution of the velocity vector by the camera operation out of it and extracting the small area in an original frame image equivalent to the component of the residual velocity vector as a moving object area. CONSTITUTION:After an original frame image is inputted, the velocity vector A of respective small areas is counted by a step 3, and camera operation B is discriminated by a step 4. By a step 5, the distribution pattern C of a velocity vector due to the camera operation B is selected from the correspondence table registered beforehand. Next, in the processing of a step 6, the component of the velocity vector equivalent to the step 5 is removed from the speed distribution diagram obtained by the step 3 and a component D is obtained. Finally, by a step 7, from the position information of the residual velocity vector component, a small area E equivalent to the component D is segmented out of the original frame image and made into a moving object area.

摘要： PURPOSE:To perform stereographic image display without applying limitation on a range being observed as stereographically by adjusting the progressive direction of light emitted from an image display plane at every picture element with a control means. CONSTITUTION:Each picture element 2 is comprised of light emitting elements 3R, 3G, and 3B having directivity, and a micro driving element 6 which changes the light emitting directions of the light emitting elements 3R, 3G, and 3B, and each picture element 2 is displayed as an image for right and an image for left alternately on a stereographic image display device 1. The head part of an observer 80 is detected with a sensor 71, and position information is analyzed with the control means 72 of the micro driving element 6, and fine adjustment such that light is emitted from a display element for right image to the direction of right eye of the observer 80, and it is emitted from the display element for left image to the direction of left eye of the observer 80 is performed. By performing such fine adjustment successively, only the right image can be always observed with the right eye of the observer 80, and the left image with the left eye. Thereby, a stereographic feeling can be obtained from every position of the observer 80.

摘要： PURPOSE:To increase the lightness of a white part and to form a color slide or the like removing distortion and having high color saturation by extracting a white signal in a color image signal after exposing a color image in each color, transferring the extracted white signal to a liquid crystal display device and correctively exposing respective colors of a transmitting light source. CONSTITUTION:One color, e.g. red(R), is selected from a color image signal 5 and transferred to a transmission type monochromatic liquid crystal display device 1, the transmitting light source 4 is emitted by the r1 of a corresponding control signal 61, and the image is recorded in a photosensitive body in a photographing device 3 by the transmitted light of the device 1. Then, other colors G, B in the image signal 5 are successively selected and the light source control signal is successively changed to the g1 of a signal 62 and the b1 of a signal 63 to record respective colors. Then, a signal W extracting a white signal in the image signal 5 is transferred to the device 1, during the period the light source 4 is emitted by signals r2, g2, b2 to execute correcting exposure for compensating the exposure lack of the white part.

摘要： PURPOSE:To easily and freely record a new color inexpressible by the information of a color image signal by using a color image generated by software for universal graphic generation, converting specific color information in the color image to a different color, and recording it on a photosensitive material. CONSTITUTION:In an arbitrary color recording operation, the color on which color conversion designated by a color designation means 4 is desired to perform is selected by the logical operations of image signals R, G, and B at every picture element, and it is displayed on a screen corresponding to the picture element as binary picture element data that is a computed result, and a hot- cathode tube is selected arbitrarily to realize an arbitrary color out of the hot-cathode tubes of three primary colors, and also, exposure time is decided by controlling the lightening time of the hot-cathode tube, and is photographed by a photographing means 5 as a requested color. In each recording operation, a horizontal synchronizing signal, a vertical synchronizing signal, and a dot clock are delayed fitting in signal delay time in the case of selecting an image signal by a control means 3, and they are sent to a transmission type panel. In such a way, it is possible to newly and easily produce the color not existing in an original color image signal sent from a host.

摘要： PURPOSE:To make illumination with various color light sources uniform in optical intensity distribution by varying distances between paired light sources disposed at both sides at respective radiating lights, and increasing the distance between the remotely paired sources from an element to be illuminated longer than that between the paired sources near the element to be illuminated. CONSTITUTION:Paired light sources 12R of red color lights, paired light sources 12G of green color lights, and paired light source 12B of blue color lights are disposed obliquely with respect to a plane. That is, when the distances between the paired light sources are W1, W2 W3, respectively they are so set as to satisfy W1>W2>W3. When the distances between the light sources 12 and a diffusion plate 14 are D1, D2, D3, they are so disposed as to satisfy D1>D2>D3. The disposition of such light sources is employed thereby to improve all the three types of the sources 12R, 12G, 12B in light intensity between the paired sources 12.
