摘要： An adaptive digital video signal processing apparatus and method for Y/C separation. In the video signal processing apparatus, an adaptive 2D BPF carries out Y/C separation through comb filtering and bandpass filtering selected according to local characteristics of an image (e.g., based on the direction in which an edge in the image extends in vertical and horizontal directions. The adaptive 2D BPF performs 2D bandpass filtering in general case. The 2D BPF adaptively executes a series of selections of the various filtering operations in a continuous manner.

摘要： For spatial resolution conversion of an image signal, a magnitude of a motion vector is compared to a threshold value. Single channel interpolation is performed if the magnitude of the motion vector is greater than a threshold value, and multi-channel interpolation is performed otherwise. In addition, single channel interpolation is performed for spatial resolution conversion of any frame that does not refer to another frame.

摘要： Provided is a method of removing noise from digital moving picture data reducing the number of frames used in a temporal filtering operation and able to detect motion between frames easily. The method comprises a method of spatial filtering, a method of temporal filtering, and a method of performing the spatial filtering and the temporal filtering sequentially. The spatial filtering method applies a spatial filtering in a YCbCr color space, preserving a contour/edge in the image in the spatial domain, and generating a weight that is adaptive to the noise for discriminating the contour/edge in the temporal filtering operation. The temporal filtering method applies temporal filtering based on motion detection and scene change detection, compensating for global motion, the motion detection considering the brightness difference and color difference of the pixels compared between frames in the temporal filtering operation, and a weight that is adaptive to the noise for detecting the motion in the temporal filtering operation. The spatial filtering method is preferably performed first, and the temporal filtering method is performed with the result of the spatial filtering.
