摘要： An image judgment device stores element characteristic information for each element of a characteristic part of a sample object and first and second positional information defining a position of each element, selects the first or the second positional information, and acquires image characteristic information for a partial image in an image frame considered as an element specified by the first positional information based on a first axis. The image judgment device also extracts image characteristic information for a partial image in an image frame considered as an element specified by the second positional information based on a second axis (which is acquired by rotating the first axis), specifies element characteristic information for an element corresponding to a position of the partial image, and judges whether the characteristic part appears in the image frame with use of the specified element characteristic information and the extracted image characteristic information.

摘要： In one embodiment of the present invention, a frame interpolation process circuit performs an interpolation process on a video signal in units of frames. A time-division gradation process circuit performs gradation level conversion for distributing brightness for one frame cycle to two sub-frame cycles, i.e., first and second sub-frame cycles. A gradation level change detection circuit detects whether a gradation level of each pixel has changed between consecutive sub-frames. For any pixel having its gradation level changed, an overshoot process circuit outputs, instead of an output signal of the time-division gradation process circuit, a video signal obtained by subjecting an output signal of the frame interpolation process circuit to gradation level conversion for emphasizing a temporal change of the signal. A predetermined-times higher speed process circuit may be added to this circuit configuration, or may be substituted for the frame interpolation process circuit. This makes it possible to improve moving image display performance, while making up for a lack of response speed of display elements.

摘要： An liquid crystal display (LCD) device uses a method for displaying halftone without causing luminance differences among pixels when an FRC technique is used, and without causing stripe-shaped luminance variations when a flicker component is eliminated spatially. The LCD device includes a data splitter, a pixel location detecting circuit, a frame number determining circuit, an applied timing memory circuit, an applied voltage determining circuit, a summation process circuit, and a timing adjusting circuit. The LCD device determines driving voltages such that for each of a high voltage or a low voltage during these 2N frames, the number of applying positive voltages is the same as the number of applying negative voltages where a unit period is 2N frames for multi-gray-level display of (1+N) levels. The LCD device can improve image quality since the average luminance of each pixel is made uniform.
