| 20090055128 | BURN-IN TEST SYSTEM FOR PROJECTION DEVICE - A burn-in test system for a plurality of projection devices includes a plurality of light sensing modules, a data collecting module, a data receiving module, and a data processing module. Each of the light sensing modules is configured for receiving light from the respective projection device and converting the light into an electrical signal. The data collecting module is configured for converting the electrical signals from the light sensing modules into a plurality of digital signals and transmitting the digital signals. The data receiving module is configured for receiving the digital signals from the data collecting module. The data processing module is configured for processing the digital signals provided from the data receiving module to obtain age information of the projection devices. | 02-26-2009 |
| 20090141037 | SYSTEM AND METHOD FOR OPTIMIZING DISPLAY COLORS OF A DIGITAL LIGHT PROCESSING PROJECTOR - A system for optimizing display colors of a digital light processing projector includes a color analyzer, and a central processing module. The color analyzer is configured for detecting a first image produced by the projector to obtain actual brightness proportions of red, green, and blue light components associated with the first image, and obtaining a color coordinate of the first image at the actual brightness proportions. The central processing module is configured for adjusting the actual brightness proportions to pre-set brightness proportions to form a second image. The color analyzer detects the second image to obtain a color coordinate thereof. The central processing module adjusts the color coordinate of the second image to a pre-set standard color coordinate, and changes the first gamma curve of the projector to a second gamma curve according to the adjusted color coordinate of the second image. | 06-04-2009 |
| 20090179836 | GAMMA CORRECTION METHOD, GAMMA CORRECTION APPARATUS, AND DISPLAY DEVICE - An exemplary gamma correction method for use in a display device is disclosed. The display device includes a lamp, and a memory. The lamp is configured to generate light which is modulated into a visual image. The memory is configured for storing a plurality of gamma correction settings. The gamma correction method comprising: measuring service time of the lamp; receiving input displayable signals; and correcting the input displayable signals using a corresponding gamma correction setting, based on the measured service time of the lamp. | 07-16-2009 |
