Description
Technical field
The present invention relates to the adjustment default value of a kind of image processing mechanism, and particularly to the method for adjustment of a kind of image processing and electronic installation thereof.
Background technology
Existing display device, such as display, TV, scialyscope etc., it is carry out, by wired transmission line (such as, the transmission line of VGA, DVI, HDMI specification), video signal and the audio signal that acknowledgement signal mechanism (such as, notebook computer or PC) sends out mostly. Recently the Wireless Display mode (wirelessdisplay) developed gradually is then that with communication (such as, Wi-Fi signal), video signal or audio signal are sent to display device, to avoid the distance limit using transmission line and to be connected complexity. Or, also utilize universal serial bus (USB) transmission line that popularity rate is higher, transmit video signal or audio signal to display device. But, the frequency range transmitted due to wireless signal limits the frequency range restriction being connected with USB, it is necessary to compress video signal to be sent or audio signal.
Figure 1A utilizes wired transmission line to transmit display data. As shown in Figure 1A, electronic installation 10 includes a central processing unit (CPU) and an image processor (GPU). Electronic installation 10 utilizes the transmission line of VGA/DVI/HDMI specification, image data is sent to display device 11 and exports, and display device 11 need not decode image data, can directly export video signal or audio signal. When film play by electronic installation 10, GPU(is generally utilized such as to be arranged at the GPU of display card) do image-decoding, again through the transmission line of VGA/DVI/HDMI specification, image data is sent to display device 11 and plays out. Current image playing program (videoplayer) can directly use GPU to do computing (such as, hardware-accelerated decoding function (hardwaredecode)), can pass through to reduce the load of CPU, to promote the overall efficiency playing film.
Figure 1B utilizes wireless transmission method or universal serial bus transmission line to transmit display data. Prior art can also utilize USB, be wirelessly transferred (such as, Wi-Fi) or Wireless Display (WirelessDisplay) technology transmits image data. The problem compatible in order to solve image playing program, generally all can close hardware-accelerated (such as, DirectDraw and Direct3D) that operating system is preset. Closing hardware-accelerated reason to be in that, some image playing program can do hardware-accelerated decoding by mandatory preferential use GPU. USB/WirelessDisplay then can capture the image data of image relief area (framebuffer) in operating system and be compressed coding (encode) process, after CPU compressed encoding, it is sent to after display device 11 does decoding process by USB/Wireless and plays back again.
Due to, operating system only open input/output end port (I/Oport) is to VGA/DVI/HDMI, but does not open to USB/WirelessDisplay, if now not hardware-accelerated closedown, just cannot capture image data from the image relief area of operating system. Therefore, the film part that display device 11 plays back will be black picture. Decode and follow-up reproduction (rendering) with GPU when playing film, but the not open USB/WirelessDisplay of operating system goes to accessing image relief area, thus results in black picture. But, unified closedown the hardware-accelerated of GPU can cause that again cpu load increases, and reduces the overall efficiency of image playing program, or causes that the speed of service of overall OS reduces. So, the side effect that picture easily pauses or picture has some setbacks can be produced. Therefore, how immediately to judge to close hardware-accelerated time point, but reduce the problem that has some setbacks play simultaneously, or open when playing film hardware-accelerated and utilize USB/ to be wirelessly transferred when transmitting image data simultaneously, reduce the situation of black picture really for problem important at present.
Summary of the invention
In sum, the present invention provides method of adjustment and the electronic installation thereof of a kind of image processing. Whether playing film according to current electronic installation, or according to can the image data of pick-up image relief area, judge to maintain or to close the function of hardware acceleration that image processor performs.

Detailed description of the invention
For the features described above of the present invention and advantage can be become apparent, special embodiment below, and coordinate institute's accompanying drawings to be described in detail below.
The present invention provides method of adjustment and the electronic installation thereof of a kind of image processing. Proposed method, mainly when transmitting display data to display device, accommodation default value, reduces the problem that display picture is black picture or picture has some setbacks. During by immediately detecting and judging that an electronic installation has broadcasting film, if this movie playback program can use " function of hardware acceleration " to cause to capture from the image relief area of operating system image data, " function of hardware acceleration " is closed. Only capture in the image relief area of operating system, the image data play simultaneously, and utilize CPU to do compressed encoding, be wirelessly transferred (Wirelessdisplay) again through USB/ and be sent to display device and carry out subsequent decoding and playing video data.
Specifically, the place that the present invention improves is in that: the setting of instant detection dynamically " function of hardware acceleration " of adjustment GPU, improve and carry out the transmission of USB/Wirelessdisplay and the overall efficiency of movie playback program simultaneously, and improve movie playback program homogeny problem (namely this there will be black picture when playing film). When electronic installation does not play film, just do not close the hardware-accelerated of GPU. When electronic installation has broadcasting to play film, then detect whether to capture the image data of the image relief area of operating system further.
When the CPU of electronic installation cannot capture the image data of image relief area of operating system, then close " function of hardware acceleration ", and change into and utilize the CPU decoding process that only image data compressed is done film, and by decoded image data compressed encoding, it is beneficial to the transmission of USB/Wirelessdisplay. When the CPU of electronic installation can capture the image data of image relief area of operating system, then do not close " function of hardware acceleration ", do the decoding of film first with GPU, CPU is to image data compressed encoding for recycling, carries out subsequent decoding and playing video being sent to display device.
The innovation concept of the present invention is in that, when utilizing USB/Wirelessdisplay to transmit display data to display device, " function of hardware acceleration " need not be used uniformly, and cause the usefulness of overall electronic installation to reduce, but by detecting whether to capture data from the image relief area of operating system, judge whether that closedown is hardware-accelerated. When closedown is hardware-accelerated and plays film simultaneously, the image data in the image relief area of operating system only can be captured. Thus, it is possible to decrease the CPU load when compressed encoding, also allow display end obtain the image frame (videoframe) of full frame when output simultaneously.
