The present invention provides an apparatus and a method for adaptively adjusting display parameters. With the apparatus and the method, an adaptive adjustment can be performed on the display parameters from the host for displaying image signals automatically according to the display attributes information of the display, so as to present the image on the display clearly.

By controlling gray scale of a display device in accordance with an average luminance of a display screen, sharp display is performed. In addition, it is an object to provide a display device with reduced deterioration of a light emitting element, by the control in accordance with the average luminance of a display screen so as to perform display appropriately. A display which includes a plurality of pixels each including a light emitting element, a switching TFT and a driving TFT, an average gray scale calculation circuit which calculates an average luminance of all pixels in a frame period, a sub-frame-number control circuit which controls the number of sub-frames in accordance with the calculated average luminance level, and a potential control circuit which controls a potential applied to both ends of a light emitting element in accordance with the calculated average luminance level are included.

An antenna pattern having a broad band characteristic as to frequencies and having a wide directivity, and an electromagnetic wave energy processing device having the antenna pattern, particularly a sheet-like antenna or electromagnetic wave shielding filter. A conductor wire forming the antenna pattern comprises an aggregated wire consisting of mesh or continuously polygonal micro-image element lines or parallel element lines. The element lines are 5-300 μm in line width and 5-1,000 μm in line pitch interval, or the most preferably 5-30 μm in line width and 5-150 μm in line pitch interval. The element lines are printed with printing ink or paste material mixed with conductive powder. In accordance with necessity, pressure treatment or polishing treatment and / or conductive plating with aid of eletroless plating or directly without aid of eletroless plating are performed on the printed surface.

The invention provides a method for defining a static high-definition image shooting area in dynamic image preview, and belongs to the field of image processing. The method solves the problems that inan existing image interception mode, an intercepted image is not clear, an original high-definition image cannot be obtained or the intercepted high-definition image is an overall picture, secondaryclipping is needed, and operation is complex. According to the technical scheme, the method comprises: obtaining an original dynamic image in real time and previewed and displayed on a display screen,and obtaining a display screen dynamic image; calculating a width ratio or a height ratio of the original dynamic image to the display screen dynamic image; intercepting an image area in the dynamicimage of the display screen, and recording the position information of the intercepted image area; and acquiring position information, width and height of an image region in the original dynamic imageregion corresponding to the captured image region according to the position information of the captured image region and the width ratio or height ratio of the original dynamic image to the dynamic image of the display screen, and storing and displaying the position information, width and height of the image region on the display screen.
