Accordingly, in the display device including the light sources arranged advantageously with respect to the manufacturing cost, the lives of the light sources can be extended by reducing the power consumption. | 12-13-2012 |
20130088613 | IMAGE PROCESSING APPARATUS AND IMAGE PICKUP APPARATUS - A determining unit determines which one of a plurality of divided areas in color distribution a value of an input image single falls within. The plurality of divided areas are defined for each of R, G, and B color components, and the determining unit determines, for each color component, which one of the plurality of divided areas the value of the input image signal falls within. An image correcting unit reads correction coefficients corresponding to the determined divided area for each color component from a correction coefficient storing unit in which correction coefficients are registered for each of the color components and each of the divided areas. The image correcting unit calculates each of R, G, and B output values of an output image signal using the correction coefficients of the individual color components read from the correction coefficient storing unit. | 04-11-2013 |
20130141611 | IMAGING DEVICE AND IMAGE PROCESSING DEVICE - A memory unit stores as conversion information which is derived based on a correction coefficient which provides, in a predetermined allowable range from a minimum value, a sum of a norm of a difference between a color difference of a correction target color and a target color which is a target of correction of the correction target color and a correction color obtained by correcting the correction target color using the correction coefficient, and a norm of the correction coefficient to which a predetermined weight coefficient is applied. A color correcting unit converts a color of each pixel of an image captured by an image capturing unit based on the conversion information. | 06-06-2013 |
20130142449 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus includes a reducing unit that reduces an input image chronologically input as moving images and accumulates a reduced image of the input image as a first reduced image in a predetermined memory. The image processing apparatus further includes a generating unit that generates, as a second reduced image, one reduced image from multiple first reduced images accumulated in the memory. The image processing apparatus further includes a smoothing unit that smooths level values of a pixel included in the second reduced image and pixels surrounding the pixel with respect to each of multiple ranges set according to the width of level values of pixels. The image processing apparatus further includes a synthesizing unit that synthesizes multiple range-by-range results of the smoothing on the basis of the input images. The image processing apparatus further includes an output unit that outputs a synthesized image as an output image. | 06-06-2013 |
20130155254 | IMAGING APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD - An imaging unit has sensitivity to visible light and infrared light and captures an image. When the distribution of the color of each pixel in the image captured by the imaging unit is calculated, a deriving unit derives a predetermined feature amount indicating the range of the color distribution. An estimating unit estimates a lighting environment during imaging based on the feature amount derived by the deriving unit. | 06-20-2013 |
20130155275 | IMAGE CAPTURING APPARATUS, IMAGE CAPTURING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM STORING IMAGE CAPTURING PROGRAM - An image capturing apparatus includes: an image capturing device in which a plurality of pixels having sensitivity to visible light and illuminating light in a certain wavelength range are arranged and that captures a moving image having a plurality of frames; a radiation device that radiates the illuminating light onto an image capturing region of the image capturing device; and a processor that executes a procedure, the procedure comprising: selecting, from among a plurality of frames captured by the image capturing device, a frame captured during an OFF period of the radiation device, and outputting the selected frame as a frame representing a visible image of the image capturing region. | 06-20-2013 |
20130194432 | IMAGING APPARATUS AND METHOD OF IMPROVING IMAGE QUALITY OF IMAGED IMAGE - An apparatus includes: an infrared light source configured to emit an infrared light within a specific wavelength band; an imaging element configured to output a color signal which corresponds to an incident light; an optical filter configured to be always inserted into an optical path to the imaging element and attenuate an infrared light with a wavelength outside the specific wavelength band; and a color corrector configured to correct the color signal output from the imaging element and approximate spectral sensitivity characteristics of each color of the imaging element in the specific wavelength band of a wavelength band of an infrared light to human cone characteristics. | 08-01-2013 |
20130241950 | IMAGE DISPLAY APPARATUS, DISPLAY CONTROL APPARATUS, AND DISPLAY CONTROL METHOD - An illuminance change detector obtains detected illuminance values from a plurality of illuminance detectors, and determines whether the illuminance value detected by each illuminance detector changed from an illuminance range to another illuminance range. When the illuminance value detected by at least one of the plurality of illuminance detectors changed from the illuminance range to the other illuminance range, an image quality control unit sets different timing to change an image quality adjustment value for a display image from an image quality adjustment value corresponding to the illuminance range to an image quality adjustment value corresponding to the other illuminance range, depending on how many of the illuminance values detected by the illuminance detectors changed from the illuminance range to the other illuminance range. | 09-19-2013 |
20130258428 | IMAGE CORRECTION DEVICE AND METHOD, AND IMAGE READING APPARATUS - An image correction device includes a processor that executes a procedure. The procedure includes: correcting an image of a read object based on images stored in a storage section of a self-illuminated reference chart image of a reference chart of size corresponding to a mounting region where the read object is mounted that has been read in advance in a state illuminated by only a self-illumination light, a uniform light standard color chart image of a standard color chart that has been read in advance in a state illuminated by only uniform light from a predetermined uniform light source, and a uniform light reference chart image of the reference chart that has been read in advance in a state illuminated by only the uniform light, and based on the image of the read object and a peripheral light standard color chart image read by a reading section. | 10-03-2013 |
20130307797 | TABLET TERMINAL AND RECORDING MEDIUM - A tablet terminal receives a triggering indication to enable a detection result of eye gaze, and sets a target area in which the presence of a target object is assumed on a screen of a touch panel using a detection position of eye gaze. The tablet terminal further displays a partial image displayed in the target area out of an image displayed on the screen in an aiming area in which a touch operation to the target area is received in place of the target area, and records a correspondence relation between coordinates of the aiming area and coordinates of the target area. When a touch operation is received within the aiming area, the tablet terminal converts the coordinates of the aiming area in which the touch operation is received into the coordinates projected to the target area using the correspondence relation recorded, and then outputs the converted coordinates. | 11-21-2013 |
