摘要： PROBLEM TO BE SOLVED: To provide a color identifying device for a drum water gage capable of instantaneously grasping an installing state at the center by identifying the color of the circular window of the gage without failing to notice even when the water level height of the gage is rapidly varied. SOLUTION: When the color image signal of a facility to be identified photographed by an ITV camera is separated to red, green and blue, A-D converted and input, a color signal luminance calculator 300 obtains the mean luminances of red, green and blue signals in a region previously set by a color identifying region setter 400 and calculates the luminance value for identifying and discriminating. Whether the luminance value is in an identifiable range or not is discriminated by a color identifying and discriminating check unit 500, and a color identifier 600 obtains three spectral stimulus values, nonnalizes them to identify the colors. Whether the color identified by the unit 700 is correct or not is checked. When the color is correct, a result output unit 800 displays the result of the red or green identified by the identifier 600 and a video signal of a scene to be identified or a synthetic video signal on a display unit 900.

摘要： PROBLEM TO BE SOLVED: To obtain a mobile object monitoring device whose detecting precision is high for following-up the behavior of an object entering a monitoring area, and for removing any disturbance without missing any intruder. SOLUTION: A picture input processing part 500 periodically fetches an input picture from an ITV camera 100, and a differential picture generating part 1500 calculates a difference between the input picture and a background picture, and a changing region extracting part 2000 binarizes the differential picture, and extracts a changing region, and an object candidate detecting part 3000 operates normalizing correlation processing between one input picture and the other input picture for each rectangular region in which the changing regions are integrated, and extracts the changing region whose similarity is low as a candidate object to be monitored. An object candidate following-up part 4000 divides the state of the candidate object into a moving mode, stop mode, and disappearing mode from a moving distance between the center of the present candidate object and the center of the previous candidate object, and detects the moving object by follow-up processing corresponding to the mode. In the disappearing mode in which the candidate object disappear in the middle, the previous candidate is held only in a holding time, and the follow-up processing is resumed when the candidate appears again.

摘要： PROBLEM TO BE SOLVED: To provide a picture monitoring system selecting a judging algorithm suited to a monitoring condition. SOLUTION: Pictures of plural monitoring areas photographed in a prescribed period by a camera 100 is analyzed by a human body extraction part 300 to extract human body pictures by each area. A human body monitoring part 600 successively fetches the human body picture by each monitoring area to calculate a moving locus. In addition, the monitoring environment of a monitoring object is obtained from a present date (year, month, day and time). When the object is a store, monitoring environment is the opening or closing of the store. A processing mode previously set in a monitoring mode table 705 to the set of this monitoring environment and a monitoring area is read out. For example some moving locus is judged to be an entering person to the store in a processing mode 1 (a monitoring area including an entrance/exit and opening the store) and is judged to be an intruder in a processing mode 4 (a monitoring area excluding no entrance/exit and closing these store).

摘要： PROBLEM TO BE SOLVED: To take an effective threatening action while tracing the movement of a trespassing body by providing a trespassing body extraction part, a trespassing body position extraction part, and a trespassing body threatening part which takes a threatening action against a trespassing body while tracing the movement of the trespassing body. SOLUTION: An image acquisition part 101 acquires image data on a monitor area from an image sensor, and the trespassing body extraction part 102 calculates differences between a previously registered background image and the input image to extract the trespassing body and further calculates differences between alternate frames or frames at intervals of several frames to extract a moving body to extract the trespassing body to be threatened. Then the trespassing body position extraction part 103 calculates the position of the body from the area of the body to be threatened in the image data and the structure and installation conditions of the image sensor. The result is reflected on the trespassing body threatening part 104 which takes the threatening action while tracing the trespassing body and an output part 105 which is installed where the trespassing body is monitored.

摘要： PURPOSE:To operate data without being conscious of a cell item by editing- processing the data for the cell fixed with a row and a column in a two-dimensional form table, scrolling the table, and extracting and designating the row or the column in the table. CONSTITUTION:When a means 2 to extract and designate the row or the column of a table preparing device extracts and designates the row or the column based on an instruction inserted from an input device 1, and the data are inputted to the cell which cannot be simultaneously displayed on the same picture together with the designated row or the column, a means 5 to control scroll does not scroll the designated row or column, and controls so that only the row or the column other than the designated one may be scrolled, and the aimed table is editing-processed. Thus, since the cell and the item corresponding to the cell are simultaneously displayed on the same picture, an operator can immediately confirms them only with visual information, and the efficiency at the time of table preparation can be improved.

摘要： PURPOSE: To process data asynchronously and to obtain a sufficient real time property by setting the data storage position in buffer memory used for transferring data between a transmission control part in a transmission station and a peripheral I/O part to a fixed position in terms of control data.
CONSTITUTION: When message data is received, the microprocessor MPU14 of the transmission control part 100 discriminates a reception station address and generates offering so as to inform the peripheral I/O part 200 of the offering only when the reception station address is of a self-station. Accordingly a MPU20 will not operate in order to access to unnecessary data, and control data can be more freely accessed. Thus sychronization is made unnecessary between the transmission control part and the peripheral I/O part in order to transfer control data, whereby the sufficient real time property can be obtained, and the access to the buffer memory can be facilitated. Moreover the continuity of message data will not be deteriorated, and data for integrating control data and message data can be securely transmitted.
