摘要： A method and a circuit for resolving the out-of-phase problem between a color burst signal and a sub-carrier signal of a television system. A delay means is used which leads to the synchronization of the color burst signal and the sub-carrier signal such that a subsequent color demodulator can demodulate correct color signals. Therefore, the locking of the two signals will be fastened without any excessively large circuit hardware.

摘要： 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.

摘要： 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.

摘要： A color correction method of an RGB signal includes the following steps. First, an original RGB-coordinate point in an RGB color space is defined according to the RGB signal, and a reference plane is obtained according to the original RGB-coordinate point. The original RGB-coordinate point locates on the reference plane, all points on the reference plane have the same value with the original RGB-coordinate point, and the reference lane is orthogonal to a value axis. Next, an intersection point of the value axis and the reference plane is defined as an origin of the reference plane. Afterwards, the hue, saturation and value of the RGB signal are independently and continuously adjusted respectively by rotating the original RGB-coordinate point around the value axis, moving the original RGB-coordinate point towards to or away from the origin and shifting the original RGB-coordinate point along the value axis to obtain a new RGB-coordinate point.
