(5) embodiment
With reference to the accompanying drawings, the embodiment to the picture adjusting method of using display unit of the present invention is described in detail.
That Fig. 1 indicates is the suitable display unit of picture adjusting method of the present invention and the connection status figure of optical disc apparatus.Above-mentioned display unit, for example television set 100 is made of parts such as display unit 10, microcomputer 11, input signal processing unit 12, tuner 13, digital interface arrangement 14, analog interfaces 15.
In addition, above-mentioned optical disc apparatus, for example 200 of DVD player are made of parts such as light picker 21, VDP (VideoDisc Play) system 22, microcomputer 23, memory 24, digital interface arrangement 25 and Analog Interface Units 26; Can be suitable for digital video interface digital interfaces such as (DVI) in the above-mentioned digital interface arrangement 25, then can be suitable for analog interfaces such as A/V port in the above-mentioned Analog Interface Unit 26.
When the user sets the picture adjustment modes of display unit 10 by button operation, above-mentioned television set microcomputer 11 by with the interface of the microcomputer 23 of DVD player 200, will receive digital startup (DE) signal.
Then, be standard with above-mentioned digital enabling signal (DE), the starting point and the terminal point of display frame are adjusted; If the starting point of display frame and terminal point can't normally be adjusted, just require to transmit simulation vertical synchronizing signal (H_sync) by the interface that is connected with the microcomputer 23 of DVD player 200, that shown in Figure 3 is digital enabling signal (DE) and simulation vertical synchronizing signal (H_sync) figure.
Follow, the vertical synchronizing signal (H_sync) that provides with above-mentioned DVD player is a standard, and the starting point and the terminal point of display frame are adjusted again again; Below this is described in detail.
What Fig. 2 indicated is the workflow diagram of using display unit picture adjusting method of the present invention, below Fig. 2 is elaborated.
S10, as in front with reference to Fig. 1 told about, when setting the picture adjustment modes of display unit 10 according to user's requirement, the microcomputer 11 of television set 100 will receive the digital enabling signal that DVD player provide by digital interface arrangement 14; If in the time of can't receiving above-mentioned digital enabling signal, will require to receive digital (DE) signal that starts by the interface that is connected with the microcomputer 23 of DVD player 200.
S11, through above-mentioned a series of processes, it is standard that the number that the microcomputer 11 of television set 100 just provides with DVD player 200 starts (DE) signal, sets the picture starting point (Start Point) and the terminal point (End Point) of above-mentioned display unit 10 especially.
Whether S12 judges the user by the vernier shifting bond(s) input instruction on the remote controller, if do not have, continues to judge in this flow process.
S13, if when the user operates by the vernier shifting bond(s) on the remote controller, above-mentioned microcomputer 11 will carry out variable adjustment to picture starting point and terminal point according to the instruction input of vernier shifting bond(s).
S14 then, is a standard with digital enabling signal (DE), confirms whether the adjustment of display frame starting point and terminal point is normally finished.
S15, above-mentioned affirmation result, when the picture adjustment can't normal termination, above-mentioned microcomputer 11 required control signal according to the transmission that user's requirements generate simulation vertical synchronization (H_sync) signal automatically, and outputs to the microcomputer 23 of above-mentioned DVD player 200.
S16, microcomputer 11 receives the vertical synchronizing signal that DVD player 200 provides by Analog Interface Unit 15.
S17, microcomputer 11 are standard with the vertical synchronizing signal just, set the picture starting point and the terminal point of display unit 10 especially, and flow process is got back to S12.
S18, when the user operated by the vernier shifting bond(s) on the remote controller, as shown in Figure 4, above-mentioned microcomputer 11 will carry out variable adjustment (as described in above-mentioned flow process S13) to picture starting point and terminal point according to the instruction input of vernier shifting bond(s); Then, be standard with vertical synchronizing signal or digital enabling signal, normally adjust the starting point and the terminal point of display frame; At this moment, be when normally finishing if in flow process S14, confirm the adjustment of display frame starting point and terminal point, when keeping picture and adjusting state, also can picture show that DVD player 200 plays the video image of output, flow process finishes.Through said process, display unit such as suitable television set of the present invention are standard with digital enabling signal or the vertical synchronizing signal that optical disc apparatus such as DVD player provide, and normally finish the adjustment of display frame; In addition the present invention can also be suitable for television set outside other display unit, various display unit such as computer display for example.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
