20080252583 | LIQUID-CRYSTAL DISPLAY APPARATUS, CONTROL METHOD THEREOF, AND COMPUTER PROGRAM - A liquid-crystal display apparatus comprising, a liquid-crystal display device driven by an AC voltage, an image divider configured to temporally divide input image data into N (N≧2) for each frame, a correction unit configured to correct a driving voltage for driving the liquid-crystal display device based on a difference between adjacent divided image data obtained by the N division, a polarity inverter configured to invert a polarity to make drive polarities of adjacent divided image data different, out of the divided image data obtained by the N division including the divided image data for which driving voltage is corrected by the correction unit, a driver configured to drive the liquid-crystal display device using the polarity-inverted divided image data, and an inversion order alteration unit which alters an inversion order for the drive polarities. | 10-16-2008 |
20090295827 | DISPLAY CONTROL APPARATUS AND METHOD OF DETERMINING DRIVING PARAMETER FOR OVERDRIVE - In order to allow a user to more easily set a correction amount in overdrive (OD) driving of a liquid crystal display device, a display control apparatus which determines a driving parameter for overdrive of the liquid crystal display device includes a first display unit which repeatedly scrolls a preset reference pattern image in one direction, a second display unit which statically displays a plurality of sample images identical to the reference pattern image and having pseudo-afterimage regions whose end portions in a scroll direction are different from each other, a selection acceptance unit which accepts selection of one sample image of the plurality of sample images, and a determination unit which determines the driving parameter for overdrive based on the difference between the pixel value of the pseudo-afterimage region of a selected sample image and the pixel value of the reference pattern image. | 12-03-2009 |
20090309890 | DISPLAY DEVICE, CONTROL METHOD THEREOF, PROGRAM AND RECORDING MEDIUM - A display device that receives an input of video signal data including a plurality of pieces of frame data, corrects frame data representing a frame to be displayed based on frame data of a frame adjacent to the frame to be displayed, and outputs the resulting data as data to be displayed on a liquid crystal panel. The device comprises a memory unit adapted to store input frame data. The device determines a correction address used to determine a frame correction amount by comparing the stored frame data and frame data that is currently input; determines correction data that represents a correction amount of the frame data based on the stored frame data and the correction address; and corrects the frame data by adding and/or subtracting the correction amount represented by the correction data to or from the stored frame data. | 12-17-2009 |
20090310018 | DISPLAY APPARATUS AND DRIVING METHOD THEREOF - A display apparatus and a driving method thereof capable of assuring reliability in frame inversion driving and improving cinema video image quality are provided. To accomplish this, a display apparatus of the embodiment replaces at least one of a plurality of frame images obtained by doubling the frame rate, with a different image before display. Specifically, the display apparatus replaces at least one of the double-speed converted plural frame images with a high-frequency emphasized image and at least one with a low-frequency component image, and displays the frame images. Furthermore, the display apparatus replaces an image at the border between cinema images with a different image before displaying. | 12-17-2009 |
20100303374 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM - According to one aspect of the invention, an image processing apparatus comprises: a unit configured to obtain an input image and a subsequent image; a unit configured to obtain N replicated images from the input image; a generating unit configured to generate a low-frequency enhanced image; a subtraction unit configured to generate a high-frequency enhanced image; a synthesizing unit configured to generate a high-frequency output image; and an output unit configured to select and output one of the low-frequency enhanced image and the high-frequency output image. The generating unit comprises a unit configured to obtain a motion vector of an object, and a filter unit configured to apply the filter to pixels around a specified pixel position Q in the replicated image, to obtain a pixel value at a pixel position P in the low-frequency enhanced image. | 12-02-2010 |
20120207399 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - A low frequency component image L[i] and high frequency component-emphasized image SH[i] are generated from an image A[i]. Lossy compression processing is performed for the low frequency component image L[i] to generate a compressed image C[i] and store it in a memory. A compressed image C[i−1] is decoded to generate a decoded image L′[i−1]. The compressed image C[i] is decoded to generate a decoded image L′[i]. A difference image E[i] between the decoded image L′[i] and the low frequency component image L[i] is generated. The low frequency component image L[i], decoded image L′[i−1], and difference image E[i] are composited at a predetermined ratio to generate a composite image SL[i]. The high frequency component-emphasized image SH[i] and composite image SL[i] are output as subframe images of the i-th frame. | 08-16-2012 |
