| 20080199102 | Block noise detector and detection method, and block noise reducer and reduction method - A block noise detector has a spatial difference calculator that calculates differences between values of adjacent pixels. A spatial difference comparator detects edges by comparing the calculated differences. Eight counters count edges detected at different groups of positions spaced eight pixels apart in each horizontal line. The maximum count and the group of positions at which it occurs are detected at the end of each horizontal line to detect block noise and the positions of the block boundaries. The block noise detector is small in size because it only has to count edges in one line at a time, and detects edges accurately by comparing the difference at a given position separately with differences to the left and differences to the right. | 08-21-2008 |
| 20080246715 | Image displaying apparatus and image displaying method - In an image displaying apparatus, first and second detecting units detect quantities of light propagating through a light path at two different locations. A variation calculating unit calculates the variation in the light quantity in the light path based on the quantities of light detected by each of the first and second detecting units. A controlling unit controls the quantity of light propagated to the screen if the variation in the light quantity exceeds a predetermined value. | 10-09-2008 |
| 20080284763 | Image display apparatus and method, and image generating apparatus and method - An image signal representing consecutive video frames is resampled, using different sampling phases so that different subsets of pixels are taken from each frame in a consecutive set of frames. The resulting set of resampled frames is combined into a single frame and transferred to an image display unit that divides the single frame into subframes and displays the subframes sequentially with different pixel shifts. Each pixel in each subframe is displayed at its correct spatial and temporal position. Although the resampling process greatly reduces the pixel data transfer rate, the image display unit can reproduce still images without loss of definition and moving images without motion blur. | 11-20-2008 |
| 20090003724 | Block noise reducer - A block noise reducer detects block boundaries in all components of an input video signal and smoothes the different components selectively on the basis of the detected block boundaries and their periodic locations. By removing block noise on the basis of block boundaries detected in color difference signals, the block noise reducer removes block noise from scenes with gradual changes in color but little or no change in luminance. | 01-01-2009 |
| 20090085896 | Image Encoding Device, Image Processing Device, Image Display Device, Image Encoding Method, and Image Processing Method - An image encoding device includes a dynamic range generator for outputting dynamic range data Dd | 04-02-2009 |
| 20090309895 | Image display apparatus, image processing apparatus, and image display method - The object of the present invention is to provide an image display apparatus, an image processing apparatus, and an image display method that are able to display images without motion blur without increasing the transmitted amount of image signal. An image display apparatus of the invention comprises an image reception unit that receives an image signal; a gray-level correction unit that corrects image signals each corresponding to sub-frames consisting of a plurality of pixel groups split from the received mage signal, using respective grayscale characteristics different from sub-frame to sub-frame; and an image display unit that displays the frame image by successively displaying the sub-frame images each having been gray-level-corrected. | 12-17-2009 |
| 20100033555 | IMAGE DISPLAY APPARATUS AND METHOD - An image display apparatus for displaying a 3D video signal using a liquid crystal device such as an HTPS or LCOS device comprises a frame rate converter ( | 02-11-2010 |
| 20100045195 | CONSTANT CURRENT SWITCHING POWER SUPPLY APPARATUS, METHOD OF DRIVING IT, LIGHT SOURCE DRIVING APPARATUS, METHOD OF DRIVING IT, AND IMAGE DISPLAY APPARATUS - In a constant current switching power supply, the current flowing through the load, is feedback-controlled based on the deviation of the detection value (Id) from the target value (Ir), multiplied by a proportional gain (PG), the value of the gain is set to a predetermined value immediately after the load switching element ( | 02-25-2010 |
| 20100045784 | IMAGE DISPLAY APPARATUS AND IMAGE DISPLAY METHOD - An image display apparatus including a display unit having a display panel; an illuminator; a number-of-lines converter for changing each of number of lines in one frame of an image-for-left-eye signal and number of lines in one frame of an image-for-right-eye signal to a reduced number of lines; a timing generator for generating a display timing signal and an illuminating timing signal; a display controller; and an illuminator driver for causing the illuminator to apply light to the display panel at timing synchronized with the display timing signal every one frame; wherein the display unit duplicates an image signal of each line of the image-for-left-eye signal of the reduced number of lines and the image-for-right-eye signal of the reduced number of lines to produce the same plural image signals for plural lines and simultaneously writes the produced signals for plural lines in the display panel to display an image. | 02-25-2010 |
