Signal extension display device, improved the demonstration resolution ratio and the color characteristic of image.
Description
Technical field
The utility model belongs to technical field of image processing, relates to a kind of signal extension display device.
Background technology
Along with the fast development of digitizing display technique and the widespread use of digital integrated circuit, ARM (AdvancedRISCMachines), as the IP supplier of embedded chip technology global maximum at present, leads industry embedded technology trend.Its IP had has become a kind of technical standard and development platform that numerous chip design company adopts.So become the developing focus of flush bonding processor based on the SOC of ARMCORE, therefore the control to embedded LCD screen is realized by ARM, if but utilized TFT screen to support display, its resolution would be on the low side, for observing and having limitation to the assurance of graphics details.
Utility model content
The problems such as in view of this, the utility model provides a kind of signal extension display device, solves picture signal display resolution low, display color characteristic difference.
The utility model is solved the problem by following technological means:
Signal extension display device of the present utility model, comprises signal processor and display panel, described signal processor, for carrying out convergent-divergent process to the picture signal of input according to default resolution; Described display panel, for showing the picture signal after convergent-divergent process.
Further, described signal processor comprises time schedule controller and image sealer; Described time schedule controller, for receiving picture signal; Described image sealer, for carrying out the process of resolution convergent-divergent to received image signal according to default resolution.
Further, described signal extension display device also comprises: the color correction device be connected with described signal processor and display panel; Described color correction device, for carrying out color correction process according to presetting resolution to the view data after convergent-divergent process; Described display panel, for the picture signal after display color correction process.
Further, described signal extension display device also comprises: the data-carrier store be connected with described color correction device and display panel; Described data-carrier store, for the view data after color correction process being stored in correct memory address, so that the correct display of view data on said display panel.
Signal extension display device of the present utility model by carrying out convergent-divergent process to original image signal according to default resolution, and carries out colour correction to the view data after convergent-divergent process, improves display resolution and the color character of image.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of signal extension display device of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail, should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
Consult Fig. 1, signal extension display device of the present utility model, comprises display panel 1, and the signal processor 2 be connected with described display panel 1.Wherein, signal processor 2, for carrying out convergent-divergent process to the picture signal of input according to default resolution; Described display panel 1, for showing the picture signal after convergent-divergent process.
Described signal processor 2 comprises time schedule controller 21 and image sealer 22, described time schedule controller 21 is for receiving picture signal, described image sealer 22, for carrying out the process of resolution convergent-divergent to received image signal according to default resolution, the process of described resolution convergent-divergent refers to first to be carried out picture element interpolation zoom in/out in the horizontal direction, and then carries out picture element interpolation zoom in/out in vertical direction.Such as: the picture signal of VGA (640*480) form is converted to XGA (1024*768) format signal, it is amplification original image being 5:8, according to above-mentioned resolution convergent-divergent, first point 8 grades of bilinear interpolations are adopted to send into differential horizontal device 5 of former horizontal direction pixels.The control of differential horizontal device is controlled together with enable signal by counter, every 5 clock intervals, differential horizontal device Enable Pin is placed in calculated difference state, 5 values entered are carried out a difference and becomes 8 new pixels, 5 clocks are waited to wait for that new value enters difference device and carries out interpolation afterwards again, until be 1 row, 1024 pixels 1 row, 640 pixel interpolation, complete a line Horizontal interpolation.Then the conversion of 5:8 is completed in the vertical direction, namely 5 column datas become the conversion of 8 column datas, Interpolation Process is, by vertical direction, 5 original column datas are adopted point 8 grades of bilinear interpolations, is transformed to 8 new column datas, until complete the amplification of whole 1 frame VGA format-pattern to 1 frame XGA image.Wherein, image sealer 22 realizes by FPGA, and FPGA comprises input timing controller, FIF01, FIF02, image sealer, output timing controller.For the resolution extension requirement that display panel is different, it can be made to possess different expanded functions, to realize original image signal to expand to different forms by writing different FPGA programs in FPGA.
Further, described signal extension display device also comprises: color correction device 3, for carrying out color correction process according to presetting resolution to the view data after convergent-divergent process, described color correction refers to the color value correcting described insertion pixel according to the color value inserting pixel surrounding pixel in resolution convergent-divergent processing procedure.Can the color value of pixel be inserted be set to the mean value of surrounding pixel color, also the color value inserting pixel can be set to surrounding pixel color and preset arbitrary color value in tonal range.Described display panel 1, for the picture signal after display color correction process.
Further, described signal extension display device also comprises: data-carrier store 4, for the view data after color correction process being stored in correct memory address, so that the correct display of view data on said display panel.When the data in data-carrier store 4 deposit certain data volume (as two two field pictures), image digital signal after the process of resolution convergent-divergent and color correction process is converted to display panel 1 data layout to display, and show the discernible image information of human eye.
Signal extension display device of the present utility model by carrying out convergent-divergent process to original image signal according to default resolution, and carries out colour correction to the view data after convergent-divergent process, improves display resolution and the color character of image.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
