To achieve these goals, the display mode selection guide method among the present invention is made up of following several stages: the frequency of synchronizing signal in phase I, the detected image signal; Whether second stage, inspection have a plurality of corresponding to the picture signal form of above-mentioned detection frequency; Phase III, at picture signal form when being a plurality of corresponding to above-mentioned detection frequency, in display mode, selecting one, and guide corresponding to above-mentioned a plurality of picture signal forms; The quadravalence section, carrying out the user according to above-mentioned guiding when selecting, will handle and export above-mentioned picture signal with selected display mode.
At this, the selection of above-mentioned display mode guiding will be finished by OSD.
Display mode selection guide device among the present invention is made up of following structure: the frequency of synchronizing signal in the detected image signal, and export synchronous detecting and the picture signal format identification device of using corresponding to the preservation picture signal format information of above-mentioned detection frequency; Above-mentioned picture signal is handled, and the image processor that is shown by display unit; For showing OSD, and osd data is offered the OSD portion that above-mentioned image processor is used by above-mentioned display unit; Provide and the user between the user interface used of interface; When being a plurality of by above-mentioned synchronous detecting and the detected picture signal format information of picture signal format identification device, control above-mentioned OSD portion, select one to be shown as in display mode corresponding to above-mentioned a plurality of picture signal forms, and play the OSD of guide function, and behind above-mentioned guiding EO, when importing selection information, control above-mentioned image processor, to handle and to export the controller that above-mentioned picture signal is used by above-mentioned selected display mode by above-mentioned user interface.
Above-mentioned synchronous detecting and picture signal format identification device obtain the picture signal format information by the desktop of corresponding one or more picture signal forms in the frequency of synchronizing signal in picture signal.
As mentioned above, by the technology of the present invention, identical in the frequency of vertical synchronizing signal and horizontal-drive signal, and in the different picture signal of its level of significance or vertical area input its for the moment, give the user with its guiding,, export the image that shows optimum display mode with by user's operation.
In view of the above, the technology of the present invention can be operated by the user, shows that with optimum state those image display devices can't accurately detect the picture signal of form, thereby fully satisfies user's multiple demand.

Embodiment
With reference to Fig. 1 the structure of the image display device that can adopt the technology of the present invention is elaborated below.
The controller 100 of above-mentioned image display device will be controlled above-mentioned image display device on the whole, and with the form that the display mode in the preferred embodiments of the present invention is guided and the user selectes, display image signals.
Above-mentioned memory 102 will be preserved the handling procedure of various information and above-mentioned controller 100.
Above-mentioned user interface 104 adopts wired or wireless user interface, and it offers above-mentioned controller 100 with the various command or the information of user's input.
Above-mentioned synchronous detecting and display mode identifier 106 will receive picture signal by paths such as D-sub, and from above-mentioned picture signal, extract horizontal-drive signal and vertical synchronizing signal, then the horizontal-drive signal of said extracted and the frequency of vertical synchronizing signal are detected, to detect the form of respective image signal.At this, the horizontal-drive signal of each form of above-mentioned picture signal and the frequency of vertical synchronizing signal will be handled by mapping in advance.That is can be one or more, by the picture signal form of handling with the frequency map of each horizontal-drive signal and vertical synchronizing signal.
Above-mentioned synchronous detecting and display mode identifier 106 offer controller 100 with above-mentioned detected picture signal format information, and the detected vertical horizontal-drive signal that reaches is offered image processor 108.
Above-mentioned image processor 108 will convert the signal by display unit 112 output usefulness from the picture signal of outside input to, and provide it to above-mentioned display unit 112.In addition, above-mentioned image processor 108 also carries out Frequency mixing processing with osd signal and picture signal that above-mentioned OSD portion 110 provides, and provides it to display unit 112.
Above-mentioned display unit 112 will be exported the image that the picture signal that provides corresponding to above-mentioned image processor 112 is provided.
Below with reference to Fig. 2 to being elaborated applicable to the display mode selection guide method in the preferred embodiment of the present invention of above-mentioned image display device.
Above-mentioned controller 100 will be checked the information whether above-mentioned synchronous detecting and picture signal format identification device 106 provide corresponding to an above picture signal form.That is, check whether frequency that above-mentioned synchronous detecting and picture signal format identification device 106 detect is (stage 200) more than one to the picture signal form of horizontal-drive signal and vertical synchronizing signal.
Being mapped to above-mentioned horizontal-drive signal and vertical synchronizing signal frequency image signal format is one when above, the display mode that above-mentioned controller 100 will correspond respectively to a detected above form is guided to the user, and the guiding user selects one (stage 202) in above-mentioned display mode.At this, above-mentioned guided procedure will be finished by OSD, select required OSD structure as shown in Figure 3 for guiding above-mentioned display mode and user in the above-mentioned controller 100.
That is to say, identical in the frequency that detects corresponding to horizontal-drive signal and vertical synchronizing signal, and during the picture signal of different 4:3 pattern in its effective field and widescreen pattern, as shown in Figure 3, above-mentioned controller 100 will be guided 4:3 pattern and widescreen pattern, and guide the user to select one simultaneously in above-mentioned two display modes.
As mentioned above, when the user selectes one of them display mode by guiding, above-mentioned controller 100 will be controlled image processor 108, to handle and output image signal according to selected display mode.
In view of the above, can't accurately detect the picture signal of form to those image display devices, also can operate by the user, output shows the image of optimum state.
