摘要： PURPOSE:To improve the efficiency of moving picture retrieval, to improve the usability, and to improve the user interface. CONSTITUTION:The kind of a file is analyzed by file kind analytic display processing S1 to display an icon showing the file in a window and the kind of the file is displayed in the icon. A tool which realizes an interactive retrieving method is displayed on a multi-window by tool display processing S2. Various tools in a tool group are selected by using a pointing device by tool selection processing S3. When the tool selected by the tool selection processing S3 is a retrieval tool, moving picture retrieval regarding the file is performed by moving picture retrieval processing S5 by using the retrieval tool. Further, when the tool selected by the tool selection processing S3 is a recording tool, the retrieval result as to the file is recorded by retrieved information recording processing S7 by using the recording tool.

摘要： PURPOSE:To prevent the deterioration of the performance of a device due to the change of a code amount caused by the inappropriate setting of a quantize step width by considering the characteristic of the picture of a processing block to be quantized in order to hold the code amount to be constant, at the time of deciding the quantize step width. CONSTITUTION:A code amount control means 20 supplies the code amount BR(m) of coded data which are coded from the start time of coding to the input time of the data of a processing block to be encoded. When the BR(m) is larger than a preliminarily set standard code amount BS, or when the BR(m) is assumed to be larger based on code amount presuming information S21, a quantize step width S22 applied to a quantizing means 7 is made to be increased. And also, when the BR(m) is smaller than the BS, or when the BR(m) is assumed to be smaller based on the S21, the S22 is made to be decreased. Thus, the appropriate setting of the S22 can be attained by considering the characteristic of the picture of the processing block to be quantized.

摘要： PURPOSE:To enable exact contour extraction while suppressing the burden of a device user at a minimum by deciding effective contour information and outputting the contour information of an input picture by adding additional contour information or eliminating unnecessary contour information with respect to the decided information. CONSTITUTION:A device user 1 designates the end point of a desired line segment to be added to a lacked part and inputs the address of the end point to a control part 16 while observing the display of automatic detection contour information S17. The control part 16 outputs the command of adding the line segment to an additional contour information calculation part 18. The calculation part 18 prepares information concerning the line segment connecting the designated end points and outputs additional contour information S18 to a picture contour information calculation part 20. While observing the display, the user 1 designates the unnecessary line segment and inputs end line segment information to the control part 16. The control part 16 outputs a deletion command signal S16c to an unnecessary contour information calculation part 19. The calculation part 19 prepares information concerning the unnecessary line segment and outputs unnecessary contour information S19 to the calculation part 20. Then, the calculation part 20 outputs the contents excluding the information S19 from contents adding the information S18 to the information S17 as picture contour information OUT.

摘要： PURPOSE:To reduce an arithmetic amount by executing the matching of feature points each other and detecting only a moving vector concerning the feature point. CONSTITUTION:A moving vector detecting means executes the detection processing of moving vectors xsi dm and eta dm only to the feature point. It is necessary to for this procesing to extract the feature point and feature point extracting means 18 and 19 are provided to a current frame picture and a past frame picture. The detected moving vector is outputted by a moving vector output means. Thus, without lowering detecting accuracy, arithmetic time can be shortened and retrieval range can be enlarged.

摘要： PURPOSE:To enhance the detection accuracy of a moving vector by detecting the moving vector of the past frame image against the present frame image together with the moving vector of the present frame image against the past frame image, and looking over through the moving vector to the present frame image against the past frame image again. CONSTITUTION:An optimum vector discriminating circuit 14 calculates an error quantity to a moving vector candidate with regard to all the moving vector candidates, whenever a notice picture element is changed, and outputs the moving vector candidate whose error quantity is the smallest as the detected moving vector. In this point, this circuit is the same as an optimum vector discriminating circuit in a conventional device, but it is different in the point that an output destination circuit is switched in accordance with a mode flag given from a mode flag switching circuit 20. In such a way, the detection accuracy of the moving vector can be enhanced.

摘要： PURPOSE:To much more improve accuracy in the correspondence of plural images by constituting the title device of linked edge detection parts for a left image and a right image, a linked edge correspondent relation calculation part and a recorrespondence processing part, etc. CONSTITUTION:The image pickup device of a left image data input part 10L and that of a right image data input part 10R are set so that the positions in a vertical direction on the image may be coincident. The left image linked edge detection part 11L and the right image linked edge detection part 11R respectively detect the linked edge equivalent to a contour in terms of the respective images. The linked edge correspondent relation calculation part 13 calculates the corresponding linked edge between the left image and the right image from left image linked edge information RL, right image linked edge information RR and initial correspondence information COR from an initial correspondence processing part 12. The recorrespondence processing part 14 divides the respective images into small areas according to the linked edges of the respective images extracted because they are coincident and executes the correspondence processing of the respective images every small divided area.
