Abstract: A display apparatus and method for processing an image in a display apparatus are provided. The display apparatus includes a display unit, a receiving unit which receives a frame image including a first image and a second image and sync information of the frame image, a determination unit which determines whether the frame image is consistent with a reference pattern using the sync information, and an image processing unit which, if the frame image is inconsistent with the reference pattern, adjusts the frame image based on a level of inconsistency, and a controlling unit which controls the display unit to display the adjusted frame image.

Abstract: The present invention discloses a color uniformity correction system for correcting color uniformity problems that exist within today's display devices. The color uniformity correction system includes a capture unit for detecting a video signal applied to a display unit and generate corresponding first color values; a storage for storing the color calibration values of a plurality of pixel locations on the display unit; a converter unit for adding the color calibration values to the first color values to generate a plurality of second color values of the video signal and a driver unit for receiving and sending the second color values to the display unit.

Abstract: A display apparatus including a display to display a picture; a signal processor to format a video signal to be output to the display; and a controller to output a control signal to the signal processor on the basis of a picture display state controlled through a control screen; wherein the picture display state is set by a user through the control screen, which is displayed concurrently with a plurality of reference screens displaying different values of the picture display state.

Abstract: An image projecting apparatus enables the formation of a projected image faithful to original image information by reducing degradation in the projected image due to decrease in imaging performance of a projection optical system. Image information is processed by an image processing device, which includes a first and a second image processor. A light modulating device modulates a flux of light emitted by an illumination optical system based on the processed image information. The modulated flux of light is projected on a screen by a projection optical system. If the image information processed by the first image processor in a pixel region is not within a representable modulation range of the light modulating device, the image information is processed by the second image processor.

Abstract: The present invention ensures the visibility of a character or a drawing displayed on a screen. The illuminance of one or more partial areas forming a display unit is measured, and a video display position is set to an area except for the partial area where the illuminance is a reference value or more.

Abstract: An onscreen display (OSD) system for a display device includes an OSD module including a microprocessor and a memory. The memory stores instructions about adjustment of a display characteristic and the microprocessor reads the instructions and generates an OSD menu including the instructions. An operation method for the system is also provided.

Abstract: A video test pattern generator and method include a control sequencer configured to control one or more address counters to generate a video test pattern. A first memory is configured to store pixel values for transitions between portions of the video test pattern and configured to store a repeated pixel value. A second memory is configured to store pattern information to determine placement of the pixel values for the transitions and the repeated pixel values. A repeat counter is configured to control a number of the repeated pixel values produced before a next transition.
