Abstract
The invention discloses an output system and a method to transfer an image plane displayed on a handhold electric device to a computer. Application software is installed on the handhold electric device containing a first display. There is a second display on the computer that is large than first display. The image plane transferring output system consists of a transferring mechanism, simulation software and a transferring output module. The transferring mechanism is charged to transfer data between the handhold electric device and computer. The simulation software is installed on a computer to listen to whether a data is needed to transfer to. When application software receives a instruction that commands to change the image plane displayed on the first display, the transferring output module transfers said instruction to computer through the transferring mechanism. After simulation software receives and executes said instruction; the image plane displayed on second display is the same image displayed on first display at executing the instruction on the handhold device.
Description
Technical field
The invention relates to a kind of portable electric device and display frame thereof and transfer out System and method for, especially in regard to a kind of screen output picture that makes computer apparatus, System and method for is transferred out in the display frame identical with the screen output picture of portable electric device.
Background technology
Because the progress of Information technology, related so that compact and powerful portable electric device arises at the historic moment. It can provide the specific functions such as general utility functions such as comprising memorandum, address list, notepad, computer, clock, game or instant messages reception, and price is more and more cheaper, so be subject to widely the acceptance of normal operation and like.
Portable electric device is because it is of many uses, often because of explanation or the needs of bulletin, must in the middle of exhibition or meeting, show its content, but cause the restriction of screen size because of the compact characteristic of portable electric device, limited to the popularity of showing, thereby the effect that has detracted and showed, and because computer apparatus general transfers the relatively large displays such as screen for computer apparatus. Just become easily solution of an economy.
With existing way, by the built-in program of the portable electric device memory with screen, be output in again on the screen after being sent to computer apparatus by the RS232 connecting line, take general portable electric device as example, its picture size is 240 to multiply by 160 pixels, so the picture of a white and black displays just needs the memory size of 4800bytes, transfer rate 9600bps with RS232 calculates, transmit a picture and need 4 seconds consuming time, so can't upgrade fast in the computer apparatus end, cause the screen picture that desultory phenomenon is arranged, can't immediately show the shown picture of display of portable electric device.
As mentioned above, how to accelerate to transfer the renewal of frame out, so that the user can enjoy better visual effect, and then raising is showed or the quality of bulletin, is problem current and to be solved in fact.
Content of the present invention
For the problems referred to above, purpose of the present invention is for providing a kind of portable electric device and the display frame system of transferring out thereof and transferring out the method for display frame from it, it can upgrade the screen output picture of computer apparatus fast, make computer apparatus screen output picture, identical with the screen output picture of portable electric device.
For achieving the above object, the invention provides a kind of display frame system of transferring out, comprise a transmission mechanism, a simulation softward and transfers out module.
