摘要： A filter for a video stream is provided. The filter generates a filtered picture according to a current picture and its previous picture. A motion difference calculator accumulates differences between current picture values and previous picture values within a neighborhood of each pixel to provide a corresponding motion difference. A histogram counter performs histogram counting according to motion differences of the pixels. A filter value calculator provides a filter value for each pixel according to operations of the motion difference calculator and the histogram counter. A blender blends the current picture value and the previous picture value of each pixel according to weightings correlated to the filter value, and provides a filtered picture value for each pixel of the filtered picture.

摘要： An image-capturing device and method for removing strangers from an image are described. First, a first image is input. Then, a control module determines if an unwanted object processing step is needed, and obtains a result. If the result is no, the first image is directly sent to an output module. If the result is yes, an image-identifying module begins to identify the target-image and the unwanted object in the first image, and then, an unwanted object processing module starts the step to process unwanted images. The unwanted object processing step can remove the unwanted object from an image and fill the left lacuna region. Afterwards, a second image is produced and sent to the output module.

摘要： A deblocking apparatus is provided. The deblocking apparatus includes a filter, a blocking detection module and a blending unit. The filter receives a target pixel of a pixel matrix to generate a filtered target pixel. The blocking detection module generates a deblocking intensity factor according to the pixel matrix. The blending unit receives the target pixel and the filtered target pixel, and dynamically blends the target pixel and the filtered target pixel to output an output pixel according to the deblocking intensity factor.
