Embodiment Construction

[0046] Please refer to the attached figure 1 As shown, the image information 1 of the computer graphics card is sent to the image processing circuit 4 through the DVI interface circuit 2 and the DVI receiving circuit 3, and then sent to the LCD liquid crystal display 6 through the drive circuit 5; another single-chip processor CPU8 accepts image adjustment The image adjustment signal sent by the device 7 is sent to the image processing circuit 4 after A / D conversion; another level conversion circuit 9 converts the control signal level of the image processing circuit 4 and the single-chip CPU8 into the level required by the LCD display .

[0047] The image signal generated by the graphics card is sent to the DVI receiver through the TMDS channel of the DVI interface. The DVI receiver converts serial-parallel to form a 10-bit digital signal for each pixel, and transmits it together with the clock signal, line and field synchronization control signals. The image processor, the i...

Abstract

The invention relates to a new color printer imager. Wherein, the image information of computer display card, via DVI interface circuit, DVI receiving circuit, to be transmitted into image processing circuit; and via driving circuit to be transmitted to the LCD liquid crystal display; another single chip CPU receives image adjusting signal sent by the image adjuster, and via A / D conversion to be fed to the image processing circuit; another electric level convert circuit will convert the control signal levels of image processing circuit and the single chip (CPU) into the level displayed by LCD; the image adjuster is a direct-current level adjuster in said circuit, which comprises brightness, contrast, channel 1 and channel 2 potentiometers, reference potentiometer, parity potentiometer, flash potentiometer and ghost potentiometer; the software in the single chip CPU inputs the adjust parameter of image adjuster into the image processing circuit to adjust.

Description

technical field [0001] The invention relates to an imaging device of a color printing machine, and relates to a quality processing technology for digital images and video images. Background technique [0002] Existing similar products generally use analog 12-bit output. When displaying liquid crystal, it is necessary to adjust the potentiometers such as brightness, contrast, vertical line, noise, and ghosting. After being used for a period of time, the attenuation of the potentiometer will have serious adverse consequences on the liquid crystal display, and it may even fail to display normally. Contents of the invention [0003] In order to improve the problems existing in the process of adjusting the image quality of the aforementioned color printing machine, the present invention provides a novel color printing machine imaging device; the device is: the image information of the computer graphics card is sent to the DVI interface circuit and DVI receiving circuit. The i...
