A probe 10 receives an echo signal, and the echo signal is stored in memory 18. Operation desk 28a has at least one readout-range setting device 34 for setting an echo signal readout-sensitivity range of the echo signal stored in memory 18. Echo signals in the sensitivity range preset by readout-range setting device 34 is read out from memory 18 from among the echo signals in the sensitivity range stored in memory 18. The echo signal read out of memory 18 is converted into data corresponding to the display dynamic range of monitor 24a by a digital gain regulation circuit 31. The converted data is inputted into image construction unit 22 to create image data. The image data is displayed on the screen of monitor 24a.

This invention relates to a line control circuit of an organic EL display screen, which applies a first grade buffer storage structure, that means to increase buffer storages and selectors and uses a synchronous way on the basis of a traditional line data serial transmission circuit on a screen to effectively reduce the loss of brightness in scanning and increase the frame frequency. Under the gray of 256 stage, when the scan circuit applies ''128-1-64-4-16-8-32-2''weight value series, the brightness loss reduces 40% and the transmission rate increases 20%.

Disclosed is a method for displaying an ultra-high-definition OSD menu, comprising the following steps: when starting an ultra-high-definition application, allocating a processing memory from a video memory of a graphics processing unit; conducting model rendering on a graphic of the ultra-high-definition application by the graphics processing unit in the allocated processing memory to acquire an ultra-high-definition application image layer; and blending and overlapping the ultra-high-definition application image layer with a preset application image layer to acquire a menu image layer, and displaying the menu image layer via an OSD menu.

The present invention provides a distributed 3D multi-channel rendering method, system and platform. The method includes the steps of: the control terminal sends a rendering instruction to each rendering channel according to a preset rendering index list; Render the corresponding sub-scene image; after the rendering of each rendering channel is completed, the control terminal sends a display instruction to each of the rendering channels; each of the rendering channels displays the corresponding sub-scene image when receiving the display instruction. The present invention can improve the resource utilization rate of the rendering channel, can effectively improve the display frame rate of the three-dimensional visualization application of the mosaic wall, better embodies the characteristics of computer parallel collaborative work, and can be quickly integrated with the existing mosaic wall system, and has high scalability. It is convenient to promote the 3D visualization application of video wall.

The invention discloses a method and system for displaying ultra-high-resolution images. After receiving ultra-high-resolution images, instead of directly performing CPU decoding, the Direct3d display technology is used to store image data as texture data. The rasterization stage of the rendering pipeline obtains the color value of each pixel, and completes the decoding process of the entire texture data according to the guidance of the encoding algorithm. The decoding process makes full use of the advantages of GPU's strong floating-point computing ability, which greatly improves the decoding rate and can significantly increase the display frame rate, making ultra-high-resolution images under high-definition display media, which greatly satisfies people's search for massive image data urgent need.

By conducting image matting, an advertisement video B in an on-site video is replaced with an inserted video C which requires to be displayed, and a rebroadcasting video which includes an on-site competition video and the inserted video C is obtained. The video rebroadcasting system also includes a video display control system (200) which rebroadcasts the rebroadcasting video to different countries and regions through the video rebroadcasting control system (300). According to the invention, the method and the system can present a default advertising video A via the on-site advertisement video display as demanded by competition holders and sponsors so as to meet demands of advertisement inter-cut of local competition sponsors, and can also rebroadcast rebroadcasting videos which include on-site competition videos and the inserted video C to other countries or regions so as to meet requirements of advertisement inter-cut of other countries or regions.

The invention discloses a method for driving a DMD (digital micromirror device) to display a high-dynamic image in an ultrahigh-frame frequency manner. The method includes the following steps that: based on requirements of a DMD to display a high-dynamic image in an ultrahigh-frame frequency manner, an image of which the pixel dynamic range is 2<N> is split into 1 to N levels of bitmaps; based on the shortest time required by DMD hardware to load the bitmaps, respective modulation display time of the 1 to N levels of bitmaps is calculated, and 1 to M levels of bitmaps which require reversion operation are determined, and the modulation display time of M bitmaps which are obtained through reversion operation is respectively set as the shortest time required by the DMD to load the bitmaps; the 1 to N levels of bitmaps and the M bitmaps which are obtained through reversion operation are sequentially loaded to the DMD and are displayed according to the set modulation time, and therefore, ultrahigh-frame frequency display of the high-dynamic image can be realized. With the method of the invention adopted, limitation on a pulse width modulation method, of time required by the DMD to load the bitmaps can be eliminated. When the method is applied to 8-bit-gray-above high-dynamic image DMD display, the display frame frequency can be significantly improved.
