    摘要: An image-encoding method and apparatus is provided for using a table statistically reflecting a selection frequency of a quantization parameter. The method includes the steps of preparing a table representing a relationship among a target bit quantity, a quantization parameter and a selection frequency as a table for statistically reflecting a frequency of selecting a quantization parameter according to a target bit quantity. The method further includes the steps of searching for a maximum selection frequency among the selection frequencies corresponding to an input target bit quantity by referring to the table, and selecting a quantization parameter corresponding to the input target bit quantity and the searched maximum selection frequency as an optimized quantization parameter to thereby prevent inadequate image-encoding due to large amounts of computations and provide a target bit rate and uniform image quality.

    摘要: A method and apparatus for processing a user interface in an image processor. In the method, at least one Region of Interest (ROI) is set on an image displayed on a screen. Location information of a renewed ROI and an image processing result based on to a location of the corresponding ROI are outputted whenever the location of the at least one ROI is renewed. An image of the at least one ROI is stored according to the image processing result. In the apparatus, a control unit extracts ROI information when the ROI is set on an image displayed on a screen, and displays location information of a renewed ROI whenever the location information of the ROI is renewed. An image signal processing unit converts the location information of the ROI extracted from the control unit into graphical data and performs image signal processing on the image of the ROI.
