20100020117 | COLOR ADJUSTMENT SYSTEM FOR DISPLAY DEVICE AND PRINTED MATERIAL - A color adjustment system for a display device includes a computer device, and a display device for displaying an image. The display device selectably displays a plurality of color temperature color presets. The computer device makes a white point adjustment to the display device, based on a color temperature color preset selected from among the plurality of color temperature color presets by a selecting operation from the computer device. | 01-28-2010 |
20100188418 | COLOR CALIBRATION SYSTEM - A color calibration system in accordance with a preferred embodiment of the present invention comprises a display device provided with a color sensor for detecting a color temperature and illuminance of ambient light, a microcomputer, and a colorimeter for performing colorimetry on a display screen of the display device from the outside. The microcomputer calculates a target value by using a preset calculation equation and a detection result on the ambient light detected by the color sensor. Then, the microcomputer automatically performs color calibration of the display device so that a colorimetry result obtained by the colorimeter may agree with the target value. | 07-29-2010 |
20100201716 | DISPLAY DEVICE AND DISPLAY SYSTEM - A display device according to the present invention includes a display which is provided on a front surface of the display device and is a display surface on which images are displayed, an illuminance sensor which is provided on a rear surface of the display device and is a first measuring unit measuring illuminance on the rear surface, and a control unit which is a first control unit controlling brightness of the images displayed on the display. | 08-12-2010 |
20100201884 | DISPLAY UNIT - A receiver receives differential analog video signals from a long distance transmission line and converts them into unbalanced analog video signals to output to an analog video signal line that is internal wiring. A frequency response characteristics corrector inside the receiver corrects the frequency response characteristics attenuated mainly by the long distance transmission line, and a delay corrector corrects differences of propagation delay. A transmitter receives the unbalanced analog video signals form the analog video signal line and converts them into balanced differential analog video signals to transmit to a long distance transmission line as differential analog video signals. A video output circuit outputs the unbalanced analog video signals or unbalanced digital video signals to a video signal line as unbalanced video signals. | 08-12-2010 |
20110254819 | IMAGE DISPLAY APPARATUS - An image display apparatus is for correcting an input image signal and displaying an image on a display unit based on the corrected image signal, and includes: an illuminance detector for sequentially detecting illuminance values around the apparatus; an illuminance analyzer for sequentially outputting image settings for correction of the image signal depending on the detected illuminance values; a setting selector for outputting an image setting which has been output from the analyzer a number of times greater than a number of times any other image setting has been output, or an image setting determined by the statistic of the image settings output from the analyzer; and a setting application unit for changing the image setting used to correct the image signal to be equal to the image setting output from the selector, when a predetermined change occurs in the input image signal or when a predetermined time has come. | 10-20-2011 |

20090073278 | IMAGE PROCESSING DEVICE AND DIGITAL CAMERA - A visual processing section | 03-19-2009 |
20090147108 | CCD signal processing device and image sensing device - A CCD solid-state image sensor alternately outputs, pixel by pixel, N (where N is an integer of 2 or more) lines of image signal and a line of smear signal for correcting the N lines of image signal by switching an output line from one to another. an AD conversion section performs an AD conversion on the output signal from the CCD solid-state image sensor. A smear data separation section separates smear data from the sensor output data output from the AD conversion section and converts the separated smear data to corrective smear data corresponding to each image data. A subtraction circuit performs a smear correction by subtracting, from each image data, the corrective smear data corresponding to the image data. Smear correction is appropriately performed even if a high-brightness object moves. | 06-11-2009 |
20100045831 | Imaging Apparatus and Image Processing Program - There is provided an imaging apparatus capable of creating RAW data subsequent to predetermined processing including distortion correction and reduction/enlargement processing of an image. The imaging apparatus includes an imaging device operable to create image data in a first color arrangement pattern (for example, Bayer array) by converting an optical signal to an electrical signal; a color arrangement conversion unit operable to convert a color arrangement pattern of the image data from the first color arrangement pattern to a second color arrangement pattern; an image processing unit operable to perform predetermined processing (enlargement, distortion correction and the like) on the image data converted by the color arrangement conversion unit; and a color arrangement reverse-conversion unit operable to convert reversely the color arrangement pattern of the image data processed by the image processing unit from the second color arrangement pattern back to the first color arrangement pattern. | 02-25-2010 |
20110181759 | IMAGING APPARATUS AND CORRECTION METHOD OF IMAGE DATA - An imaging apparatus is provided for reducing noise which is derived from random noise contained in a correction signal used for correcting an image data and is newly generated on correction of the image data. The imaging apparatus drives vertical transfer registers with no signal charge from photoelectric transducers read out to the vertical transfer registers to obtain and store a correction signal into a field memory. The apparatus subtracts the correction signal from the image data by a subtractor. | 07-28-2011 |
