|20150271409||IMAGE QUALITY ADJUSTMENT APPARATUS, CORRECTION DATA GENERATION METHOD, AND IMAGE QUALITY ADJUSTMENT TECHNIQUE USING THE APPARATUS AND METHOD - An image quality adjustment apparatus obtains correction data for correcting display unevenness of a display panel by capturing an image of the display panel using a camera, and includes a moire frequency control unit that performs a control to position the display panel and the camera at a predetermined relative angle with respect to each other, an unevenness measurement unit that measures the display unevenness of the display panel based on the image captured by the camera, and a correction data generation unit that generates the correction data based on the unevenness measured by the unevenness measurement unit. Arranging the panel and the camera at the predetermined relative angle shifts a spatial frequency component of a moire pattern occurring in the image captured by the camera out of a region where a spatial frequency component of the display unevenness is present, and removes an influence of the moire pattern.||09-24-2015|

|20140118558||IMAGE QUALITY ADJUSTMENT APPARATUS, IMAGE QUALITY ADJUSTMENT CIRCUIT, AND DISPLAY PANEL - Provided is an image quality adjustment apparatus that can measure display unevenness for each pixel with higher accuracy than in the conventional art. An image quality adjustment system includes an image quality adjustment apparatus that generates correction data corresponding to a display panel, a test pattern generation device that causes the display panel to display a test pattern image, and a ROM writer. The image quality adjustment apparatus measures unevenness based on images of a display state of the display panel that are captured using cameras, and generates correction data for correcting the display unevenness that occurs due to manufacturing variations of the display panel. A feature of the present invention is that the image quality adjustment apparatus includes a plurality of cameras, and an image of a single display panel is captured using the plurality of cameras to obtain unevenness data of the display panel.||05-01-2014|
|20130155042||IMAGE CORRECTION DATA GENERATING SYSTEM, IMAGE CORRECTION DATA GENERATING METHOD, AND IMAGE CORRECTION DATA GENERATING PROGRAM FOR DISPLAY PANEL USING UNPOLISHED GLASS - An image correction data generating system for a display panel that uses unpolished glass is equipped with a signal generator, an imager, and a controller. The signal generator supplies the display panel with a signal for causing that display panel to output an image. The imager captures an output image. The imager is able to resolve an area smaller than the individual pixel sizes of a plurality of pixels. The controller is equipped with an instructing unit, an image acquirer, a high-pass filter, and a correction data generator. The instructing unit outputs instructions for supplying a signal value shared across the entire surface of the display panel to the signal generator. The image acquirer acquires output image data from the imager. The high-pass filter computes high-pass data by applying high-pass filtering to the output image data. The correction data generator outputs an image correction table corresponding to the high-pass data.||06-20-2013|
