20090016633 | IMAGE PROCESSOR, DISPLAY DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM - By sequentially scanning pixel lines of an image signal that has been received as input linear interpolation application regions, which are regions in which gray-level changes are to be smoothed, are detected for each line of the input signal, and the detected linear interpolation application regions are then subjected to an gray-level extension process. The regions that have been subjected to the gray-level extension process are further subjected to a process of limiting, to within prescribed values, gray-level changes in a second direction that differs from the direction in which the linear interpolation application region detection process was carried out. | 01-15-2009 |
20090040246 | IMAGE PROCESSING DEVICE, DISPLAY DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM - An image processing device includes a detector for detecting a linear-interpolation-applicable area and an expansion corrector for performing a gradation expanding process on the linear-interpolation-applicable area detected by the detector.

20090129685 | IMAGE PROCESSING APPARATUS, IMAGE TRANSMITTING APPARATUS AND METHOD AND PROGRAM OF THE SAME AND DISPLAY DEVICE - In an image processing/transmitting apparatus and method, graininess is suppressed while remarkably the appearance in the image area with a smooth gradation and the flat image area, the number of bit planes is reduced and then increased. The second image processing module includes a bit adding module executing bit adding based on the two-dimensional dither matrix for compressed data read from memory and obtaining decompressed data, an LPF processing threshold value generator obtaining a threshold value from decompressed data, and an LPF processing module attaining a difference between decompressed data of a pixel and decompressed data of a peripheral pixel, which sets a result of weighted mean processing for decompressed data of the pertinent and peripheral pixels to the output image data if the difference is within the threshold, and which sets the decompressed data of an arbitrary pixel to the output image data if the difference value>threshold. | 05-21-2009 |
20090244086 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, PROGRAM THEREOF, DISPLAY DEVICE, AND IMAGE DISPLAY SYSTEM - An image processing apparatus, an image processing method, and a program thereof, and a display device are provided, in which reproduction of a secret image from one dispersed image is difficult. A secret image and a reverse image included in at least two types of images are in a relationship of forming image data of an image not correlated with the secret image when luminance values of image data respectively are added pixel by pixel. Included are: a memory | 10-01-2009 |
20090262127 | IMAGE PROCESSING APPARATUS, DISPLAY APPARATUS, AND IMAGE DISPLAYING SYSTEM - An image processing apparatus, a display apparatus and an image displaying system wherein both secure and public images can be efficiently displayed with high quality without lowering the contrast of the public images. There are included a memory ( | 10-22-2009 |
20100013957 | IMAGE PROCESSING APPARATUS, METHOD AND PROGRAM, AND DISPLAY APPARATUS - The invention provides: a code generation and data assignment circuit that sets the order in which a confidential image and a reversed image are displayed, based on an orthogonal code; and a shutter glass control signal generation circuit that controls so that during a period when an image signal of an image including at least part or all of the confidential image is outputted, the shutter glasses disposed between the succeeding display apparatus and the user's eyes are set in a light transmission state and during a period when another image is displayed, the shutter glasses are set in a light shielding state. The image signal of the confidential image and the image signal of the reversed image are in a relationship such that when the brightness values of the images are added together for each pixel, the resultant image has no correlation with the first output image. | 01-21-2010 |
20100020237 | DISPLAY CONTROLLER AND DISPLAY APPARATUS - The present invention provides a display controller and a display apparatus capable of carrying out image display in a high-speed screen switching mode without changing a data rate of a digital transmission path while a signal itself sent through a display transmission path is kept within a standard (60 Hz). A display controller | 01-28-2010 |
20100085373 | IMAGE PROCESSING APPARATUS, METHOD, PROGRAM AND DISPLAY - This invention is to provide an image processing apparatus, an image processing method, a program, and a display in which both of a secret image and a public image can be efficiently displayed with high picture quality without reducing contrast of the public image. One of output images is a secret image which displays an input secret image as one of input images in a partial area of a screen, all the output images including the secret image have a relationship to become, when a luminance value of each pixel thereof is totaled, an input public image as one of the input images; and during a period in which at least the secret image is being outputted, shutter glasses disposed between a display to which the image signals are inputted and user's eyes are set to a light transmission state. | 04-08-2010 |
20100097409 | DISPLAY DEVICE AND DISPLAY METHOD - A display device is provided with a display section; a drive section driving the display section; and a light shutter control section controlling a light shutter. The display section is configured to display first and second images on the display section during a specific period. The drive section is configured to allow perceiving an image only from a direction in a specific viewing angle range at least during the specific period. The light shutter control section controls the light shutter so that the light shutter is placed into a transmitting state allowing transmitting light during a period during which the first image is displayed in the specific period and placed into a shielding state shielding light during a remaining period in the specific period. The first and second images are generated so that an image generated by adding brightnesses of respective pixels of the first and second images has no correlation to the first image. | 04-22-2010 |
20100182500 | IMAGE DISPLAY DEVICE, IMAGE DISPLAY METHOD AND IMAGE DISPLAY PROGRAM - An image display device is provided with an image memory for storing a first image as a target secret image; a synthesizing section for time-multiplexing the stored first image and a second image obtained by reversely converting the luminance of the first image; and an image display section for displaying the time-multiplexed image. An optical shutter which transmits light at the time of displaying the first image is arranged to the synthesizing section. The image display device is also provided with a display characteristic detecting section which fetches information regarding to the display characteristics of the image display section, and an image converting section which converts the first image into the second image, based on the fetched display characteristics of the image display section. Thus, the image display device effectively shields image display from a third party, even when the display characteristics of the the image display section are changed. | 07-22-2010 |
