摘要:
In a state in which a reference light source emits light, display elements of a display device are caused to light up in each of lighting patterns for causing any adjacent display elements not to light up simultaneously. A captured image acquirer acquires image data about an image captured in each of the lighting patterns, a display element position calculator determines the position of each of the display elements and the position of the reference light source on each of the images, a display element brightness calculator calculates brightnesses from the pixel values at the determined positions, a relative brightness calculator calculates a relative brightness of each of the display elements with respect to the brightness of the reference light source, and a display element output coefficient calculator calculates coefficients for making the brightnesses of the display elements uniform.

A method detects short term, unusual events in a video. First, features are extracted features from the audio and the video portions of the video. Segments of the video are labeled according to the features. A global sliding window is applied to the labeled segments to determine global characteristics over time, while a local sliding window is applied only to the labeled segments of the global sliding window to determine local characteristic over time. The local window is substantially shorter in time than the global window. A distance between the global and local characteristic is measured to determine occurrences of the unusual short time events.

An apparatus and a method for managing issuance of turnaround tickets include a ticket issuing unit for issuing turnaround tickets and test tickets, a separate reading unit for reading the issued tickets, and a control unit for controlling the issuance of turnaround and test tickets. In particular, the test ticket issuing unit issues a test ticket with predetermined test data printed thereon at a predetermined time intervals for use in testing. The turnaround ticket issuing units issues continuously issues a stream of turnaround tickets each having predetermined turnaround ticket data printed thereon until a next test ticket is issued. The test ticket is fed through the reading unit to check the quality of the printed test data. The next set of turnaround tickets are issued only if the test ticket print quality coincides with the known predetermined test data.

A brightness adjusting device including a display unit position determining part for determining the position of each display unit in a coordinate system on a pattern image shot by a camera, a shooting angle determining part for determining a shooting angle of the camera with respect to each display unit from the pattern image, and a brightness measuring part for determining the display image displayed on each display unit in the pattern image with reference to the position of each display unit to measure the brightness of each display unit, and adjusts the brightness of an image display device in consideration of the light distribution characteristic value of the image display device, the shooting angle measured by the shooting angle determining part, and the brightness of each display unit measured by the brightness measuring part.

A memory card comprises an index area, and a data area including a plurality of extents in each of which data is recorded. The index area includes in correspondence with each of the extents, an area for entering a file name, a status indicating area for entering the number of bytes to be recorded per sector, and areas for entering the beginning and end addresses of the corresponding extent, respectively. The memory card is accessed in such a way that the index area is read to decide if a desired file name exists, and that the status indicating area is read subject to the existence of the desired file name. A control unit translates an address premised on a floppy disc into an address for accessing the memory card, on the basis of the number of bytes entered in the status indicating area, and then accesses the memory card.

A data distribution system selects the distribution means having the most suitable distribution cost among a plurality of distribution means corresponding to a destination. The data distributing system includes a distribution information memory for storing a distribution information list including available distribution means corresponding to each of a plurality of destinations, a distribution cost memory for storing distribution cost information corresponding to a plurality of distribution means and distribution conditions, a selector for selecting distribution means having the lowest distribution cost for each destination from a plurality of the distribution means extracted from the destination information list stored in the distribution information memory corresponding to each destination when the destination information is inputted, referring to the distribution cost information, and a distribution data output apparatus for distributing the data to the destination using the distribution means selected by the selector.
