Abstract: A video encoder, a video decoder and a video system are provided. The video encoder performs a video encoding operation on a first video frame stream to generate an encoded stream to the video decoder, wherein the encoded stream contains deblocking filtering information. The video decoder performs a video decoding operation on the encoded stream to generate a second video frame stream. The video decoder determines whether to forcibly perform a deblocking filtering operation on a current block of a current frame of the second video frame stream according to the deblocking filtering information.

Abstract: An image processing method and an image processing apparatus that utilize scrolling text information and moving edge-pairs of an edge map to determine text regions in interpolated frame is introduced herein. Text blocks are detected according to the moving edges-pair of the edge map. Next, a first moving vector histogram and a second moving vector histogram are built according to the detected text blocks. An existence of scrolling text and motion vector of the scrolling text in the frames are determined according to the first and second moving vector histograms. A scrolling text region in at least one of the first frame and the second frame is determined in block line unit, and positions of each scrolling text pixels in an interpolated are determined according to the motion vector of the scrolling text and the scrolling text region in the at least one of the first frame and the second frame.

Abstract: The disclosure provides a method and an image processing device for video bit-rate control. The method includes the following steps. A designated distortion value and a maximum bit-rate value are received. A Lagrange multiplier and a quantization parameter (QP) of a current frame among a sequence of video frames are estimated according to the designated distortion value and the maximum bit-rate value. The current frame is encoded according to the estimated Lagrange multiplier and the estimated QP.

Abstract: A video encoding apparatus and a video encoding method are provided. The video encoding apparatus comprises an encoding circuit and a region of interest (ROI) determination circuit. The encoding circuit performs a video encoding operation on an original video frame to generate an encoded video frame. The encoding information is generated by the video encoding operation during an encoding process. The ROI determination circuit reuses the encoding information generated by the video encoding operation to identify one or more ROI objects according to the initial ROI and generates one or more dynamic ROIs for tracking the one or more ROI objects within a current video frame for any one of a plurality of sequential video frames following the original video frame.
