Abstract: PURPOSE:To exactly attain the electron beam focus adjustment of a CRT, and to easily attain an automation. CONSTITUTION:A prescribed pattern P constituted of plural lines L1-L4 is displayed on the screen of a CRT 1, photographed by a line width measuring means 3, and the line width W1-W4 of each line is calculated. Then, each line width Wi(i-1-4) is multiplied by a coefficient alphai(i=1-4) different according to the shape of the electron beam, that is, complete round or ellipse, and the total sum SLW=SIGMAalpha iWi is calculated by a line width total sum calculating means 4. Then, the focus circuit of the CRT 1 is adjusted so that the line width total sum SLW can be the minimum by a focus adjusting circuit control means 5. Thus, a voltage added to the focus electrode of the CRT 1 is adjusted, and the just focus state of the electron beam can be obtained. Therefore, the focus adjustment of the electron beam can be exactly attained, and the automation can easily be attained.

Abstract: PURPOSE:To remove crosstalk components generated due to a system characteristic of a color video camera or the like without deteriorating the level of an original color signal. CONSTITUTION:For example, at the time of photographing an object in a red color, original color signals Ra, Ga, and Ba supplied from a color video camera 3 are supplied to a maximum level signal detecting means 11, and the original color signal Ra in the maximum level is detected. Then, a switching signal is supplied from the maximum level signal detecting means 11 to switching means 13R, l3G, and 13B. Thus, the original color Ra in the maximum level is outputted from the switching means 13R, and specific signals Gb and Bb transmitted from specific signal transmitting means 12G and 12B are outputted from residual switching means 13G and 13B. The specific signals Gb and Bb are set to '0', and then the crosstalk components Ga and Ba expect the original signal Ra can be removed.

Abstract: PROBLEM TO BE SOLVED: To easily detect a specified color picture-converting picture data of a picture to be processed so that the specified color becomes a coordinate axis in a color difference space. SOLUTION: When an operator selects an HSI mode in a picture processor 4, it detects the judgment center of the specified color corresponding to a hue, lightness and saturation, and sets a threshold for specified color detection with the respective judgment centers as the center. When the operator selects either a first or second color difference mode, the picture processor 4 executes an arithmetic processing and transforms the coordinate of an object color so that a straight line connecting the coordinate of the objective color and an original point in the color difference space becomes the horizontal coordinate axis (x) of the two-dimensional orthogonal coordinate space. A rectangular area is set in the color difference space which is coordinate-transformed so that the straight line connecting the coordinate of the objective color in the color difference space to the original point becomes the horizontal coordinate axis (x) of the two-dimensional orthogonal coordinate space, and picture elements distributed in the area are detected and the specified color is detected.

Abstract: PURPOSE:To precisely control the temperature of a display device by carrying the display device as an subject to be inspected at a preheating part in a measuring part after its temperature is controlled, and measures a displayed image while the temperature is controlled. CONSTITUTION:The liquid crystal display (LCD) panel 101 is held at set temperature on a measuring stage part 5 and in a measuring part room, IC circuits 17 and 26 inspect the electric characteristics. If a defective is found, it is carried by a handler part 8 to a defective tray part 13 and the optical characteristics are inspected. Then a video signal obtained by the photography of a CCD camera 3 is sent to an image processing board 24 and an image processing CPU 23 decides whether or not there is a defect and its extent. The handler part 8 carries a new LCD panel 1101 onto a preheating stage part 34 from a supply tray part 10 and next inspection is started. Then other LCD panels 101 are held at the set temperature at the time of the measurement and precisely measured.

Abstract: PURPOSE:To suppress the overlapping of a label and to make possible the measurement of a CRT or an LCD for which the accuracy of a luminance level is required by using the two-dimensional coordinate of an image memory as the label at the time of executing labelings in parallel. CONSTITUTION:An image memory 3 is accessed by a vertical direction coordinate (v) and a horizontal direction coordinate (h). In this case, when the object of a labeling exists and a picture element under consideration (coordinate address v, h) represents it, the label for the object of the labeling is generated by a function L (v, h). In a system where image processings are possible to be performed in processing circuits which are separated with each other in parallel, the generation of a unique lebel is made possible when the labeling is performed.

Abstract: PURPOSE:To detect defective pictures not only by points but also by lines or planes by storing photographed video images as the pixel data of a display device in a frame memory provided in a picture processing means. CONSTITUTION:RGB signals outputted from a CCD camera 11 for photographing a liquid crystal panel 10a are digital converted at the A/D converter 12a of a picture processor 12 and stored in the frame memory of a picture processing part 12b as the pixel data. Then, the levels of respective memory cells in an address area in which the pixel data are stored are two-dimensionally compared and calculated and when the level data of the memory cell to be a center are a maximum value, it is recognized that a picture element is present at the position. Thus, by obtaining the level data and the addresses of the respective picture elements as frame memory address data inside the picture processing part 12b, at the time of displaying, for instance, total black, total white or gray as the intermediate color, etc., the defective picture elements can be detected not only by the points but also by the lines or the planes.
