Fig. 1 is display correction structure drawing of device provided by the embodiment of the utility model, as shown in Figure 1, the utility model
Embodiment provides a kind of display correction device, comprising: display module, sensor module and correction module.Display module is used
It is shown in receiving business picture signal and business picture signal being sent to display screen, and receives what correction module was sent
Image signal correction is simultaneously sent to display screen in the form of picture-in-picture and shown by image signal correction；Sensor module is for acquiring school
The chrominance information and luminance information of positive image signal generation image；Correction module receives sensing for sending image signal correction
The chrominance information and luminance information of device module acquisition, and correction is generated according to image signal correction and chrominance information and luminance information
Data.
Picture-in-picture (picture in picture, abbreviation PIP), principle are to use simple two-way signal channel, all the way signal
As small picture signal source, small picture is superimposed on big picture and shows as big picture signal source by another way.
Business picture signal is the picture signal that display is shown in a normal mode of operation, and business picture signal is logical at this time
Cross the display that display module input panel carries out operating mode.
When carrying out display timing, correction module triggers the output of image signal correction, and image signal correction passes through display
The processing of module is shown on a display screen simultaneously with business picture signal.Display module is by image signal correction and business image
Signal generates superimposed image, is exported with picture-in-picture mode and is shown to display screen.At this point, the display of image signal correction is not
It will affect the display of normal business picture signal.
Sensor module acquisition correction picture signal corresponds to the brightness of display screen information and chrominance information of display portion, will adopt
Collect obtained above- mentioned information and is sent to sensor module.Correction module is corresponding to read the luminance information and coloration letter that sensor is sent
Breath, that is, obtain true brightness information and chrominance information of the image signal correction after display screen is shown.
All brightness values of tri- color of RGB are successively measured, for example, the display brightness value range of 8bit is 0-255, i.e. RGB
(0,0,0)-RGB(255,255,255).Correction module combines the image signal correction issued and each luminance information of three colors received
With each chrominance information, correction data is produced.
Display screen is shown according to correction data, to realize the correction of display.Such as it is raw according to correction data
Correction at color characteristic file, when for display display.
Display correction device provided by the embodiment of the utility model sends image signal correction by correction module, connects
The chrominance information and luminance information for receiving sensor module acquisition, generate correction data.It can conveniently realize display
Correction, can carry out display to automatically correct operation, without external computer and measuring device, without manually being configured,
Correction course is more easy.
Content based on the above embodiment, as a kind of alternative embodiment, which further includes trigger module, trigger module
For sending the trigger signal for implementing display correction to correction module.By trigger module, can with the correction of trigger scope,
For example, physical button can be set over the display or combined by physical button, when pressing above-mentioned key, trigger module triggering
Correction module implements the correction of display, to complete the correction of primary display.
Meanwhile by the setting of trigger module, it can be achieved that the customized calibration function of display, including setting timing execute
Correction, display automatically correct after powering on.
Content based on the above embodiment, as a kind of alternative embodiment, which further includes memory module, memory module
For storing each correction data in school.Each correction data is stored by memory module, it on the one hand can be according to storage
Correction data when configuration file is lost fast quick-recovery, on the other hand the correction data of storage can be used as later maintenance and state
Tracking.
Content based on the above embodiment, as a kind of alternative embodiment, correction module includes the ARM with operating system
Mainboard, ARM mainboard export comparison result for correction data to be compared with normal data.
The avatar of normal data includes the RGB curve of standard, and ARM mainboard generates correction RGB song according to correction data
The curve is compared by line with the RGB curve of standard, judges whether current curves state has met curve standard requirements.If
Meet, then can be reserved for corresponding correction data and judges report；If not satisfied, can be corrected again by correction module.
For example, medical display needs to meet the standard of DICOM 14, this standard specifies 0~4000cd/m2 brightness
All brightness separations (JND) that human eye can be differentiated in range, the corresponding gray scale levels in each brightness separation.Ideally want
Ask each grey menu of display brightness will with to correspond to the brightness of grayscale on 14 standard curve of DICOM consistent such as right
In 0-255 grades of grey menus, display R, G, the B parameter under every level-one grey menu are corrected, the Gamma of display is made
Curve mutually approaches the DICOM curve of standard.
In addition, can be managed to display correction by ARM mainboard, be corrected the effect assessment of curve, generation is commented
It observes and predicts and accuses and save report of accessment and test in local log, be convenient for later maintenance and status tracking.
