A method and an apparatus of color-space conversion are provided herein. When adjustment of saturation and/or hue is performed on a RGB color signal, pixel luminance will be influenced to some extent. In the conversion method of the present invention, luminance compensation will be performed after global or local adjustment to keep the pixel luminance from being influenced by the color-space conversion. The luminance compensation method is to adjust a compensation value according to a ratio of an adjusted pixel luminance to an original pixel luminance.

The present invention provides a method of noise reduction applied in digital video signal processing according to the following steps. A video signal is received initially; after the adaptive spatial filtering, a basic signal is generated. The basic signal is then divided into a number of N bandwidth divisions of spatial domain signals. Each spatial domain signal is undergone a corresponding adaptive temporal filtering and a plurality of corresponding temporal filtered signals is generated. Each temporal filtered signal is undergone individual noise estimation, and a corresponding feedback signal is generated in order to control the corresponding adaptive temporal filtering. In the end, all temporal filtered signals are summed up to a processed video signal; where N is a natural number.

A slicer level calculator including a signal detector, a moving average calculator, a sync-tip voltage sample circuit, a blanking voltage sample circuit, a slicer level calculator, and a rear-end processor is disclosed. The signal detector determines whether an input video signal satisfies a low signal to noise ratio (SNR) criterion. If so, the first signal detector further enables a low SNR control signal. The moving average calculator obtains a moving average voltage level of the input video signal. The sync-tip voltage sample circuit, the blanking voltage sample circuit and the slicer level calculator obtain a sync-tip voltage level, a blanking voltage level, and a slicer voltage level, respectively. The rear-end processor selectively executes low-pass filtering operation on the slicer voltage level in response to the low SNR control signal.

A state detector of a video device and a state detection method thereof are provided. The state detector includes a first chroma detector, a second chroma detector, and a controller. The first chroma detector and the second chroma detector operate in a first state among a plurality of states. When the second chroma detector is not capable of processing an input signal normally, the controller controls the second chroma detector to switch between the states until the second chroma detector operates in a second state to process the input signal normally, and the first chroma detector is set to operating in the second state. As a result, the quality of a displayed image is improved.
