20100020240 | IMAGE SIGNAL PROCESSING APPARATUS, IMAGE SIGNAL PROCESSING METHOD AND VIDEO DISPLAY APPARATUS - The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion. | 01-28-2010 |
20100074536 | IMAGE SIGNAL PROCESSING APPARATUS AND IMAGE SIGNAL PROCESSING METHOD - To perform an image processing for high resolution more suitably on even an image signal having images with different resolutions mixed therein. An image signal processing method of the present invention includes the steps of: performing a spatial low pass filter processing on a first image signal that is an input image; generating a second image signal by performing an image processing for high resolution on an image after the low pass filter processing; comparing corresponding regions in the first image signal and the second image signal; and selecting either of the first image signal and the second image signal with respect to the region based on this comparison result. | 03-25-2010 |

20110243227 | MOVING PICTURE DECODING METHOD AND DEVICE, AND MOVING PICTURE ENCODING METHOD AND DEVICE - The objective is to reduce the amount of code in the encoding/decoding process for a moving picture. In an intra prediction process, the degree of ease of estimating the prediction direction or the block mode for a block to be decoded is determined based on the prediction direction data or the block mode for multiple adjacent blocks which have been decoded previously and which are adjacent to the block to be decoded; the prediction direction data or the block mode for the block to be decoded is decoded based on the result of said determination; and intra prediction is performed based on the decoded prediction direction data or the block mode to generate decoded image data. | 10-06-2011 |
20120236183 | IMAGE TRANSFER SYSTEM, IMAGE TRANSFER METHOD, IMAGE RECEPTION APPARATUS, IMAGE TRANSMISSION APPARATUS, AND IMAGE PICKUP APPARATUS - In order to transfer an image encoded at a high compression rate and suitably increase the resolution of the transferred image, it is provided an image transfer system, comprising: an image transmission unit that transmits an image; and an image reception unit that receives the image transmitted from the image transmission unit. The image transmission unit scales down the image, and transmits the scaled-down image to the image reception unit. The image reception unit calculates an angle between a line displayed in the image transmitted from the image transmission unit and a horizontal direction of the image in correspondence with pixels included in the image, scales up the image transmitted from the image transmission unit, and removes an aliasing component of the scaled-up image based on the calculated angle. | 09-20-2012 |
20120301012 | IMAGE SIGNAL PROCESSING DEVICE AND IMAGE SIGNAL PROCESSING METHOD - When super-resolution processing is applied to an entire screen image at the same intensity, a blur contained in an input image is uniformly reduced over the entire screen image. Therefore, the screen image may be seen differently from when it is naturally seen. As one of methods for addressing the problem, there is such a method that: when a first image for a left eye and a second image for a right eye are inputted, each of parameters concerning image-quality correction is determined based on a magnitude of a positional deviation between associated pixels in the first image and second image respectively; and the parameters are used to perform image-quality correction processing for adjusting a sense of depth of an image. | 11-29-2012 |
20130208113 | Image Monitoring Apparatus, Image Monitoring System, and Image Monitoring System Configuration Method - An image monitoring technology for accurately collecting information about a monitoring target is provided. An image monitoring apparatus according to the present invention tracks the monitoring target on the basis of images sent from an overhead camera and images sent from gazing cameras, and switches gazing targets for the gazing cameras on the basis of the position and event information of the monitoring target, and tracking information about the monitoring target. | 08-15-2013 |

20090041452 | Camera Cover - It is an object of the present invention to mount a focusing mechanism of a camera device on a vehicle without bringing the mechanism in contact with a worker's hands in an in-focus state of a lens system in the camera device having an eyelid part for preventing stray light covering part of a lens, and to improve the beauty and increase mounting flexibility. In a camera cover according to the present invention, a cylinder body ( | 02-12-2009 |
20100140059 | OPERATING DEVICE AND OPERATING SYSTEM - A mode switching switch and a dial switch are coaxially provided. A spring member is fixed to a linkage unit of the dial switch. The linkage unit is inserted through a click number change member, which has a cylinder unit and a shaft. The shaft is inserted into a guide groove formed on a cylinder unit of the mode switching switch. By the rotation of the mode switching switch, the click number change member is moved in the axial direction. On the inner circumferential surface of the cylinder unit of the click number change member, two click surfaces on which the different numbers of concaves or convexes are formed in the circumferential direction are aligned in the axial direction. By the movement in the axial direction of the click number change member, any one of the click surfaces is engaged with the spring member. | 06-10-2010 |
20100141610 | MANIPULATOR - A selecting operation and a setting operation for setup items shown on a display are performed with using a selection change switch that can in steps rotate to three positions indicated by marks and a dial switch that is stacked on the selection change switch. The display shows three setup items at three locations. In a case that the selection change switch is rotated and a tip portion of the selection change switch indicates a position, it is thought that the selection operation is performed to select a setup item shown at a location corresponding to the indicated position. Then, the setting operation for the selected setup item is performed by rotating the dial switch. When the selection change switch has pivoted toward near side or far side, a window to be shown at the foreground is changed on the display. | 06-10-2010 |
