Embodiment
The present invention provides a kind of detection method, storage device and the detection means of TV images uniformity, to make this hair
Bright object, technical solution and advantage are clearer, clear and definite, and the embodiment that develops simultaneously referring to the drawings is to of the invention further detailed
Explanation.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Below in conjunction with the accompanying drawings, by the description to embodiment, the content of the invention is described further.
The invention provides a kind of detection method, storage device and the detection means of TV images uniformity.Such as Fig. 1 institutes
Show, the detection method of the TV images uniformity comprises the following steps：
S100, when television set shows test image, obtain the vision signal of the test image.
Specifically, used image when the test image is detects TV images uniformity, because television set shows
When showing different images, color and bright secretly degree etc. that different images is presented differ, to improve the accuracy rate of detection, often
When one television set is detected image consistency, it is required for showing the test image, all television sets is shown same
Color during individual image, it is bright it is dark etc. detected, so as to judge the image consistency of all television sets.
After the television set receives the control instruction for showing the test image, the test image is shown on screen,
Obtain the vision signal that the television set is sent by the display test image simultaneously.Described in being shown when the television set high definition
During test image, the vision signal is LVDS（Low-Voltage Differential Signaling low-voltage differentials）Form
Vision signal；When the television set is super shows the test image clearly, the vision signal is the video of VByOne forms
Signal.
When described when television set shows test image, also include before obtaining the vision signal of the test image：
Selection refer to television set, the first vision signal that acquisition is described to be exported when showing the test image with reference to television set；
First vision signal is converted into rgb format；
First vision signal of rgb format after conversion is stored as reference video signal.
Specifically, when carrying out image consistency detection to multiple television sets, a display is chosen from multiple television sets
Color and bright dark degree etc. all reach the television set of default display standard as refer to television set during test image, thus by its
Its television set judges that the test image that other television sets are shown refers to television set with described compared with the reference television set
Whether the test image of display is consistent.
When it is described show the test image with reference to television set when, it with reference to television set is the display test chart to obtain described
As and the first vision signal for exporting, when it is described show the test image with reference to television set high definition when, first video is believed
Number be LVDS forms vision signal；When the reference television set is super shows the test image clearly, the first video letter
Number be VByOne forms vision signal.No matter first vision signal is the video of LVDS forms or VByOne forms letter
Number, it is required for being converted to first vision signal vision signal of rgb format.
When receiving the second control instruction, have been converted into rgb format first vision signal it is stored with
As reference video signal, i.e., described reference video signal is the vision signal of rgb format.Second control instruction can be
Sent with the first switch with reference to television set wired connection, or with the remote control with reference to television set wireless connection
Device is sent, i.e., the second control instruction described in when user presses the first switch is sent, and the reference video signal is stored
Get up, or when user presses the corresponding button on remote control, second control instruction is sent, the reference video signal quilt
Store.
S200, the similarity according to the vision signal and the reference video signal prestored calculating between the two.
The similarity according to the vision signal and the reference video signal prestored calculating between the two is specific
Including：
Its rgb video signal after being converted to rgb format is obtained according to the vision signal；
Obtain the reference video signal prestored；
The similarity between the rgb video signal and the reference video signal is calculated according to the computational methods pre-set.
Specifically, obtain after the television set shows the vision signal that the test image is exported, by LVDS lattice
Formula or the vision signal of VByOne forms are converted to the vision signal of rgb format；Then the ginseng prestored is obtained
Vision signal is examined, is rgb format because the vision signal of rgb format is identical with the signal format of the reference video signal,
So directly it can be believed according to the computational methods pre-set to calculate the vision signal of rgb format and the reference video
Similarity between number.
The computational methods are that histogram matching or the image similarity of matrix decomposition method or distinguished point based calculate.Compared with
Good embodiment, the similarity make to be expressed as a percentage, and the computational methods are histogram matching, and histogram reflection is
The probability distribution of image pixel gray level value.
S300, when the similarity is more than or equal to preset value, the vision signal and the reference video signal one
Cause.
Preferably, the preset value is 95%, and when the similarity is more than or equal to the preset value, the video letter
It is number consistent with the reference video signal, i.e., described television set with it is described show the test image with reference to television set when one
Cause property is qualified, and the detection of image consistency can be carried out to next television set.
When the similarity is less than the preset value, i.e., described similarity is less than 95%, the image of the television set is consistent
Property it is unqualified, now need user to adjust its screen parameter either manually or by the master control borad of the television set, until the similarity
It is qualified；Or corresponding relation between similarity and screen parameter is pre-set, when the image consistency of the television set does not conform to
During lattice, according to the corresponding relation between the similarity and screen parameter, the screen parameter of the television set is adjusted automatically
Section, so that the television set shows that the test signal exported during the test image shows the test with described with reference to television set
The vision signal exported during image is consistent, improves the display quality of television set array.
Preferred embodiment, when receiving the first control instruction, export and show the similarity；Another is preferably real
Apply example, similarity given a mark, pre-set the corresponding relation between similarity and score value, as full marks be 10 points, as 80% ＜
During similarity ＜ 90%, score value corresponding to the similarity is 7 points, as 90% ＜ similarity ＜ 95%, score value corresponding to the similarity
For 8 points, when similarity=95%, score value corresponding to the similarity is 9 points；When similarity is more than 95%, corresponding to the similarity
Score value is that full marks 10 divide；When receiving the first control instruction, the similarity and its corresponding score value are together exported simultaneously
Display.
The present invention also provides a kind of storage device, wherein, the storage device is stored with computer program, the computer
Program is able to carry out to realize the detection method of as above TV images uniformity described in any one.
