20080212306 | AMBIENT LIGHT SYSTEM AND METHOD THEREOF - An ambient light system applied in a TV including a display panel, a loudspeaker and a plurality of ambient light sources includes an audio level detector, a pattern generator, and an ambient light controller. The audio level detector detects the level of an input audio signal to obtain a detected level. The pattern generator generates an ambient light pattern based on the detected level by reference to a selected operation mode. The ambient light controller controls the intensity of one or more ambient light sources based on the ambient light pattern. | 09-04-2008 |
20080218467 | BACKLIGHT CONTROLLER AND SCALING FACTOR USING FULL RANGE SEARCH AND LOCAL RANGE SEARCH METHOD - A backlight controller generating a scaling factor for scaling the intensity of a backlight illuminating a LCD (LCD) is provided. The backlight controller includes a histogram generator and a scaling factor selector. The histogram generator generates a histogram in response to an input frame image of the LCD. The scaling factor selector includes a luminance distortion estimator and a loop controller. The luminance distortion estimator estimates a luminance distortion for each candidate scaling factor with reference to the histogram. The loop controller selects a scaling factor among the corresponding to a maximum acceptable distortion among the estimated luminance distortions, so as to scale the intensity of the backlight. | 09-11-2008 |
20080278623 | ADAPATIVE DE-INTERLACER AND METHOD THEREOF - An adaptive de-interlacer can convert an interlaced video signal into a progressive video signal, and comprises a motion detector, an intra-field interpolator, an inter-field interpolator, a motion aliasing artifact detector and a blending unit. The motion detector generates an alpha value for each interpolated pixel in a current field of the interlaced video signal based on successive fields of the interlaced video signal. The intra-field interpolator outputs an intra-field interpolated pixel based on the current field, and the inter-field interpolator also outputs an inter-field interpolated pixel based on the successive fields. Afterward, the motion aliasing artifact detector detects whether the interpolated pixel is located in a motion aliasing area. The blending unit receives and mixes the intra-filed interpolated pixel and inter-filed interpolated pixel based on the alpha value from the motion detector and the detection result from the motion aliasing artifact detector so as to determine the interpolated pixel. | 11-13-2008 |
20080317374 | Method of modifying brightness of color pixels - An apparatus includes an extractor, a first subtractor, a second subtractor, a third subtractor, an offset generator and an adder. The extractor receives the color pixel and to provides a first, a second, and a third image value, wherein the first, the second, and the third image values are associated with the brightness of the color pixel. The first subtractor calculates a first offset between the first image value and a first expected image value. The second subtractor calculates a first difference between the first and the second image values. The third subtractor calculates a second difference between the first and the third image values. The offset generator defines a linear relation based on the first offset and the first image value, and generates a second and a third offset. The adder receives the second offset, the third offset, the second image value and the third image value to generate a second and a third expected image value. | 12-25-2008 |
20090041374 | System and Method for Edge Direction Detection for Spatial Deinterlace - The system for edge direction detection for spatial deinterlace comprises an ignored region detector and an edge direction detection unit. The ignored region detector is configured to receive a first type field of a video frame and to define a search region based on the first type field. The edge direction detection unit is configured to select an edge direction within the search region. The edge direction is associated with an interpolated pixel located on one of a plurality of second type lines of a second type field, where the search region is smaller than the first type field. | 02-12-2009 |
20090046202 | DE-INTERLACE METHOD AND APPARATUS - A de-interlace method is performed by the following process. First, edge directions of pixels surrounding a target pixel to be interpolated in an interpolating line are received, and a search range selected from the edge directions of the surrounding pixels is determined by checking a consistency of the edge directions of the surrounding pixels. Sequentially, an edge direction of the target pixel is determined based on the search range, and a pixel value of the target pixel is generated based on the edge direction of the target pixel for interpolation. | 02-19-2009 |

20090274367 | IMAGE COMPRESSION AND DECOMPRESION METHOD CAPABLE OF ENCODING AND DECODING PIXEL DATA BASED ON A COLOR CONVERSION METHOD - An image compression and decompression method encodes and decodes pixel data based on a color conversion method. Based on the relationships of corresponding color components of two adjacent pixels, the corresponding color components are encoded either by a white and black modification, a down-sampling or an edge modification. Based on the relationships of encoded color components of the two adjacent pixels, the corresponding encoded color components are decoded either by an inverse white and black modification, an up-sampling or an inverse edge modification. | 11-05-2009 |
