Embodiment
A preferred embodiment according to the present invention is a kind of image adjusting apparatus.In this embodiment, image adjusting apparatus is to be arranged between image input media and the image display, receives the input image and produces image output to image display in order to the self imaging input media.
In fact, the kind of image input media and image display does not have specific restriction, and for example, the image input media can be computer, recreation device main frame, DVD player, VCD player or other similar electronic installations; As for image display then can be LCD, plasma display or other similar display device.
Please with reference to Fig. 1, Fig. 1 is the functional block diagram that illustrates the image adjusting apparatus of this embodiment.As shown in Figure 1, image adjusting apparatus 1 is electrically connected between image input media 2 and the image display 3, and image adjusting apparatus 1 will receive the input image by self imaging input media 2, and produces image output to image display 3.For example, image adjusting apparatus 1 can be an element programmable gate array (Field Programmable Gate Array, FPGA), but not as limit.In addition, image display 3 also is electrically connected to video signal source 4, video signal source 4 in order to provide video signal (for example advertisement video signal, but not as the limit) to image display 3.
Wherein, the signal transmission interface between image adjusting apparatus 1 and the image input media 2 can be that HDMI/DVI interface, demonstration connectivity port (DisplayPort) interface, D-Sub interface or AV synthesize/the S-Video interface, but not as limit.Can be the HDMI/DVI interface, show connectivity port interface or D-Sub interface as for the signal transmission interface between image adjusting apparatus 1 and the image display 3, but also not as limit.
In this embodiment, image adjusting apparatus 1 comprises the first resolution detection module 10, the second resolution detection module 11, auto zoom coefficient generation module 12, auto zoom module 13 and image rotary module 14.Wherein, the first resolution detection module 10 electrically connects image input media 2 and auto zoom coefficient generation module 12; The second resolution detection module 11 electrically connects auto zoom coefficient generation module 12 and image display 3; Auto zoom coefficient generation module 12 electrically connects the first resolution detection module 10, the second resolution detection module 11 and auto zoom module 13; Auto zoom module 13 electrically connects image input media 2, auto zoom coefficient generation module 12 and image rotary module 14; Image rotary module 14 electrically connects image display 3, auto zoom module 13 and is arranged at the outer buttons transcoder controller 15 outside the image adjusting apparatus 1.
It should be noted that; Because the image rotary module 14 in the image adjusting apparatus 1 of this embodiment is to be electrically connected between image display 3 and the auto zoom module 13; Represent the input image among this embodiment to carry out after the auto zoom earlier, be rotated via image rotary module 14 again and become the image output that exports image display 3 to through auto zoom module 13.Next, the function that each module that is comprised with regard to image adjusting apparatus 1 is respectively possessed is carried out detailed introduction.
The first resolution detection module 10 is in order to first signal of the input image that detects image input media 2 and imported.In practical application, the kind and the form of the input image that image input media 2 is imported do not have specific restriction, for example BMP form, JPG form or other image formats.Please with reference to Fig. 2 A, Fig. 2 A illustrates the detailed functions calcspar of the first resolution detection module 10 among Fig. 1.
Shown in Fig. 2 A, the first resolution detection module 10 comprises storage element 100 and the detecting unit 102 that is electrically connected to each other.Wherein, storage element 100 records horizontal resolution and vertical resolution corresponding to varying level synchronizing signal and vertical synchronizing signal in order to store the display stopwatch in the display stopwatch.When the first resolution detection module 10 receives first signal of input image; Detecting unit 102 will detect horizontal-drive signal and the vertical synchronizing signal in first signal, and seeks out the corresponding first horizontal resolution and the first vertical resolution from storage element 100 stored display stopwatchs.For example, the first horizontal resolution of detecting unit 102 detected input images and the first vertical resolution can be 2400X1600 pixels, but not as limit.
In practical application, what storage element 100 was stored can be the common discrete display stopwatch of video signal frequency electronic standard association (VESA), shown in Fig. 2 B.Can know by Fig. 2 B; If the frequency of horizontal-drive signal of input image is 43.3 kilo-mega cycles per seconds, and the frequency of the vertical synchronizing signal of input image is 85 hertz, and then can obtain the first horizontal resolution is 640 pixels; The first vertical resolution is 480 pixels, but not as limit.
