Abstract: PROBLEM TO BE SOLVED: To quickly carry out a quantitative flicker inspection. SOLUTION: An image displayed on a display is imaged for a specific time, division into a plurality of minute regions is carried out for each of a plurality of image data regarding the imaged image, and the amount of change in luminance based on the transition of the luminance within the specific time is obtained for each of the plurality of divided minute regions. Then, the amount of change in luminance to a specific frequency is mapped corresponding to the image for generating mapping data, and an occupation region that is occupied by data exceeding a specific threshold is extracted from the mapping data. After that, the total of the amount of change in luminance in the occupation region is obtained, and additionally the total obtained for each specific frequency is added as flicker determination values Tx 1 to Tx 24 . The flicker determination values Tx 1 to Tx 24 are compared with a preset judgement reference value T, thus performing the accept/reject decisions of a flicker. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To make quantitatively evaluatable the sensual picture quality of spot, etc., and to stabilize and improve the picture quality of an examination picture, preferably, of an LCD panel by fetching an image on the LCD panel in the state of turning on the examination picture on the LCD panel, processing and evaluating the fetched image. SOLUTION: First of all, a picture for examination is displayed on the LCD panel (step 1). Next, this displayed image on the LCD panel is fetched as the digital data image of 512×512 pixels, for example, and the fetched image is digitized to the value of 256 gradations, for example (step 2). Next, the digitized image is differentiated and the contour part of the spot is made actual (step 3). Next, a picture quality index L is found while utilizing the area for each gradation value (step 4). Afterwards, the found picture quality index L is compared with a predetermined quality standard L0 (step 5). When L is almost equal with L0, it can be known the examined LCD panel is the same quality level as the quality standard (step 6).

Abstract: PROBLEM TO BE SOLVED: To smoothen the operation of a torque hinge mechanism, to stably fix the mechanism at a desirable angle, and to hold the lubricant for a long time by providing at least two ring-like friction plates to be commonly inserted on a shaft and for pushing to each other with a non-passing recessed part in a friction surface thereof. SOLUTION: Two ring-like friction plates 40, 42 to be commonly inserted on a shaft and for pushing to each other are provided, and the lower side friction plate 40 is formed with a non-passing recessed part 46. In case of standing still, the lubricant 48 is held by the recessed part 46 between the friction plates 40, 42, and the friction plates 40, 42 are made to contact with each other at other parts except for the recessed part 46. When the friction plate 40 is rotated in a rotating direction 52 and the friction plate 42 is rotated in a rotating direction 54, pressure of the lubricant 48 is gradually raised by the inclination 44, and a remarkably high pressure oil film is formed between the friction surfaces 56, 58. This oil film generated by the wedge effect is instantaneously spread over the surface of friction surfaces 56, 58, and the initial torque value is lowered. The lubricant 48 is quickly supplied so as to smoothen the operation, and the mechanism can be stably fixed at a desirable angle, and the lubricant 48 can be stably held for a long time.
