Description of the invention (1) The present invention relates to a video camera that can detect the viewing angle-dependent defects of the inspection target panel such as an LCD panel; and a camera equipped with the camera LCD device ft quality inspection device for optical devices such as computers. As for the defects of the LCD (Liquid Crystal Display) panel, white dots, black dot defects and line defects observed from the front of the LCD panel 110 can be detected by a conventional LCD panel quality inspection device. However, among the LCD panel defects, there are still viewing angle-dependent defects as shown in Figure 14, and the defects are only found when viewed from an inclined plane. Therefore, as shown in Figure 13 (a) _, if the LCD panel is observed from the oblique angle of a conventional video camera *, as shown in Figure 13 (b), only part of it will be in focus; It becomes a skewed day image, so it cannot be measured and checked. Therefore, for defects in viewing angle dependence, visual inspection has been carried out all the time. As mentioned above, basically a normal lens or camera is viewed from the front. If it is viewed from an oblique surface, one part will focus and the other part will not be able to focus. In addition, when the image taken from the oblique surface is compared with the image taken from the front, the image will be skewed when the image is taken. The first object of the present invention is to provide an image quality inspection of a liquid crystal display panel. The device, which is integrated in the entire LCD panel 110, focuses and ingests the LCD image seen from the inclined surface, and obtains the full LCD pixel position as the pixel address of the CCD (Charge Coupled Device) in the self-skewed screen, and Incorporate the LCD image faithfully, and judge the defect of viewing angle dependence. In order to achieve the above purpose * In the present invention, there is a first CCD camera capable of measuring the brightness and darkness of the LCD from the front, and a built-in CCDS domain meter, and a first dimension CCD camera measuring the brightness and darkness of the LCD from the inclined plane, and a built-in 2 (^ 卩 Photograph paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) 1 ^ ----;-U— 装 -------- 打 ----- f-line (please read the precautions on the back before filling in this page) 298628 at _ B7 V. Description of the invention (2) Color machine. Among them, the second CCD color camera is to measure the brightness of the LCD from the inclined plane, while Μ is usually If you focus on one part *, the other parts will not be able to focus. Therefore, when viewing from an inclined plane, a tilt-through dysprosium or built-in transmissibility is built in to enable full focus on the LCD panel. In addition, because the second CCD camera is viewing the LCD image from an oblique surface, a skewed image may be generated on the CCD pixel. In order to convert the anamorphic image on the skewed CCD pixel into a normal LCD image * The LCD panel ft quality inspection device is equipped with an LCD driver that displays the calibration coil sample or test pattern on the LCD panel to be inspected; The CCD pixel performs the A / D conversion of the measured brightness and darkness of the measured image; a CCD address setting mechanism of an LCD pixel, which is a day image measurement unit, which performs the detected brightness of the M CCD pixel A / D change, and use the calibration data of the calibration sample and the real number of M to specify the position of the LCD pixel and the corresponding CCD pixel, and the real value of the sampling address of the full pixel of the LCD is obtained from the address of the above-mentioned bright point ; In addition, there is a pre-sampling processing mechanism, which uses the above sampling address to make a linear tween, and it becomes a portrait of the number of pixels of the LCD panel. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please first Read the precautions on the back and then fill out this page) In addition, there is also a defect judgment mechanism for specifying defects based on the brightness and darkness of LCD pixels obtained from the image of the M LCD panel; and a control unit that controls the full ram rolling distance * and A display unit that displays the LCD image and controls the operating status. The liquid crystal display panel day quality inspection device constructed as described above takes the LCD day image focused from the oblique plane into the LCD panel and takes in focus from the oblique surface CCD pixels The full LCD pixel location of the address enables faithful ingestion of LCD images to determine viewing angle dependent defects. The second objective of the present invention is to provide a paper standard that can detect viewing angle dependent defects. The Chinese National Standard (CNS) is applicable.

Description of invention (3) Camera and an image quality inspection device for an LCD panel using the camera, in which the camera is compatible with The LCD panel fully ingests the LCD daylight image seen from the oblique surface, and basically does not produce skew *, enabling the LCD to be faithfully captured as a faithful ingestor. In order to achieve the above-mentioned object, in the present invention, there is provided a color camera composed of an imaging element and a lens > wherein the imaging element is movable relative to the lens mirror surface * in parallel in all directions. With respect to the surface of the LCD panel to be inspected, the moving mechanism of a color camera that can move in the vertical direction and in parallel in all directions in parallel with the upper imaging element and the lens is movable. In addition, there is also an A / D conversion unit that converts the portrait data built from the camera into digital data; and a CPU control unit, which is used to control the above-mentioned imaging elements, camera and camera movement , And calculate and process the ft image that has been converted into digital data, and check the defects of the day image. In addition, there is a set of front and slopes of the LCD panel to be inspected, and the imaging element and the! F mirror are cameras parallel to the LCD panel to be inspected; a set of cameras will be produced by each camera The A / D conversion part of the portrait data of the digital data is converted into digital data; a multiplexer is used to infuse and output the above A / D conversion units; and a digital data is converted into digital data. Just like doing arithmetic calculations and checking the CPU for like defects. In addition, a group is provided on the front and slope of the liquid crystal display panel to be inspected, and the imaging element and the lens are parallel to the object panel to be inspected; a day image data from each camera Ml is selected by Μ, and the The output data selector; 1.
