摘要:
In a mark detecting system using an image pickup device such as a TV camera in which a mark in the form of a regressive reflector is provided on an object, the field of view of the image pickup device is illuminated with light of a specified wavelength from an illuminating device placed in the vicinity of the image pickup device. The reflected light is introduced on the image pickup device through a filter capable of cutting off light having wavelengths other than the specified wavelength. Since the mark forms a bright pattern on an image produced within the field of view of the image pickup device, the position of the mark can be easily detected by means of a data processor which processes image signals.

A pattern recognition system comprises a partial pattern cutting out system which has a plurality of cutting out windows previously provided in correspondence with a plurality of regions in a specific pattern which respectively correspond to a characteristic part of the specific pattern to be recognized and which constitute patterns symmetric to each other. A binary input signal is cut out by the use of the partial pattern cutting out apparatus. The "EXCLUSIVE OR" function between the corresponding bits of the partial patterns obtained from the plurality of cutting out windows are evaluated by "EXCLUSIVE OR" circuits. The number of outputs of predetermined logic level among the outputs of the "EXCLUSIVE OR" circuits and a preset number are compared, and the coincidence between both the numbers is sought. When both numbers coincide, the inputted signal is recognized as being the specific pattern.

A pattern recognition system comprises a picture tube for picking up an object to be recognized, a partial image pattern cutting out apparatus which, in turn, outputs a plurality of partial image patterns cut out from an image pattern obtained from the picture tube, the partial image patterns being output in synchronization with the scanning of the picture tube and a memory storing a plurality of partial standard patterns. Each of the partial image patterns is compared with the respective partial standard patterns and the respective partial image patterns similar to each partial standard pattern are grouped every partial standard pattern. A group of the partial image patterns, each of which is closely spaced from each other in a position of two-dimensional coordinate is selected from each group of the grouped partial image patterns and the respective representative positions of the respective elected groups of the partial image patterns are calculated. The shape and the position of the object to be recognized can be detected from the fact that the respective representative positions are closely spaced from each other in a position of a two-dimensional coordinate.

A coded label comprising a code pattern in which first and second segments respectively being substantially square and having reflection factors different from each other are arranged in at least four rows and two columns, and in which at least two of either of the first and second segments are arranged in each column and at least one is arranged in each of the uppermost and lowermost rows.

This method for recognizing a specific pattern is characterized in a process of extracting feature parts wherein one or more certain feature parts of specific shape are extracted from an input pattern; the next feature part is then extracted from an extracting area which is determined from the position on the input pattern where a previous feature part was extracted; and in case that the next feature part fails to be extracted from the extracting area so determined, the initial condition is restored thereby extracting the feature part by successively limiting extracting areas.

A circulating memory apparatus and a data storage and distribution system using a circulating recording area effectively and having an improved access efficiency to the circulating recording area are disclosed. A memory area secured in a disk unit is used in circulation thereby to record the time series input data. The time series input data are edited into a data block of a predetermined size including a plurality of subblocks, and written into the disk unit by data block. In response to a request for outputting specific data, the data are read by subblock from the disk unit into a cache memory thereby to selectively output the specific data contained in the subblocks.

A method for editing an image on a display unit, an apparatus for executing the method and a computer program product for the method, wherein a predetermined CG object is designated in an image on the display unit, and in order to edit the image, a first command list for speech, motion, moving image reproduction or audio reproduction is displayed on the display unit, a command for editing the designated CG object is selected from the first command list and executed for the designated CG object. In the method of editing the image on the display screen and the apparatus for executing the method, the position information of the CG object located in the CG studio on the display unit and the information on the position and orientation of the camera for imaging the CG studio are read from a memory, it is determined whether the CG object selected by the pointing device is a CG character or a property, the information on the position to which the pointing icon has moved on the display unit by manipulating the pointing device is acquired, and the selected CG object is moved to the position to which the pointing icon has moved. Based on the information on the position to which the CG object has moved, the data on the character set-up window is updated in the case where the CG object is a CG character, and the data on the studio set-up window is updated in the case where the CG object is a property. The selected CG object can be dragged to the desired position by the pointing device.

A method of characterizing a video includes the steps of extracting frame images from an input video, calculating a time length between each of the frame images and a next one of the frame images, assigning index information determined by the calculated time length to each of the frame images, stringing together the index information assigned to the frame images, and characterizing the input video by the strung-together index information. The index information is a character code, and the strung-together index information is a character code string. The frame images include head frame images located at scene changes of the input video. The input video is being broadcasted or is included in a data base.

A method and apparatus for processing a moving image displayed on a display unit. Images representative of sets of frame images forming said moving image to be processed are displayed on a display unit. The moving image includes a plurality of scene images. Each of said scene images is divided into a cut image which comprises a set of frame images, and each cut image is divided into a plurality of sub-areas. The representative frame images of said respective sub-area of the frame images are designated as representative images. Data of the representative images are linked to respective predetermined keys of an input device. In response to an operation of one of the keys, the representative image linked to the operated one of said keys is displayed on the display unit.

A computer-aided editing method of moving image information comprises designating an edition range of original moving image information, applying a special effect processing to the moving image within the designated edition range by an editing apparatus, registering the moving image information applied with the special effect processing as one cut to a memory device, and registering the moving image information outside the designated range as other cuts to the memory device. A computer-aided editing apparatus of moving image information comprises a memory device for storing original moving image, moving images after editing processing and an edition position-associated information, an input device, an editing device for applying a special effect processing to a designated range of the original moving image read out from the memory device in accordance with an image processing program, a control device and a display device. The moving image information applied with the special effect processing is registered as one cut to the memory device and the moving image information of the original moving image outside the designated range is registered as other cuts to the memory device. The display device displays the original moving image information, symbols representing an edition start point and an edition end point inputted by the input device, the information on the special effect processing and the information on the length of the image of the cut.
