Description
Technical field
The present invention relates to flat panel TV reproduction ratio adjustment technology field, in particular to a kind of flat panel TV carries out weight automatically
The method of aobvious rate adjustment.
Background technique
Reproduction ratio be TV images test an important indicator, refer mainly to television screen reproduction image programs with
The ratio between the image of signal source transmission image programs.Television manufacturer requires the tv product to each project before TV volume production
Reproduction ratio adjustment is carried out, shows equipment Industry standard regulation to reach China's DTV.
Currently, the image reproduction rate method of adjustment that generallys use of flat panel TV is to manually adjust, this adjustment mode because
It is manually adjusted while needing people to visually observe adjustment effect, integrated regulation rhythm is more slow, inefficient.
Summary of the invention
It is insufficient in above-mentioned background technique the purpose of the present invention is overcoming, a kind of automatic carry out reproduction ratio of flat panel TV is provided
The method of adjustment, to save time and human cost, improves the reproduction of image to realize the reproduction ratio adjust automatically of flat panel TV
Rate adjusts the efficiency of work and can be used for flow line production.
In order to reach above-mentioned technical effect, the present invention takes following technical scheme:
A kind of method of the automatic carry out reproduction ratio adjustment of flat panel TV, specifically includes the following steps:
A. control flat panel TV is switched to corresponding information source, and reads preset data file and determine that flat panel TV requirement is shown again
Rate；
B. according to information source and reproduction ratio require to generate corresponding specific reproduction ratio adjustment signal and by the specific reproduction ratio
Adjustment signal is exported to flat panel TV and is shown；
C. reproduction ratio setting is automatically adjusted until plate according to the color bits digital level sampling to display image border
TV reaches corresponding reproduction ratio standard requirements；
D. resulting reproduction ratio setting data will be adjusted to automatically write panel TV software system and export corresponding heavy aobvious
Rate data file.
Further, the step B specifically includes the following steps:
B1. the white field of full width of corresponding resolution, the white field lower-upper length of full width are generated according to the resolution requirement of information source
For the long H of corresponding resolution ratio, left and right height is the high V of corresponding resolution ratio；
B2. one lower-upper length of reproduction ratio β and generation required according to the reproduction ratio of information source is H1, and left and right height is
The black field of V1, wherein H1=β × H, V1=β × V；
B3. the black field in the step B2 is covered on the basis of absolute center on the white field that step B1 is obtained, i.e.,
Obtain specific reproduction ratio adjustment signal；
B4. the specific reproduction ratio adjustment signal is exported to flat panel TV and is shown.
Further, when carrying out value to H1, V1 in the step B2, if can not be rounded according to calculation formula H1, V1,
Then take adds 1 mode to carry out data rounding processing in the part after erasing decimal point and the units value before decimal point.
Further, the step C specifically:
C1. the center of the edge up and down pixel of the image-region shown to flat panel TV carries out color bits digital level
Sampling, if a length of H0 of image display area, a height of V0, then the coordinate of four sampled points be respectively (H0/2,0), (0, V0/2),
(H0/2, V0), (H0, V0/2)；
C2. the value for checking the color bits digital level of four sampled points, judges whether its value is 0, to color bits digital level
Reproduction ratio register of the value not for the 0 corresponding edge of sampled point carries out increase adjustment, and return step C1 carries out the sampled point
Color bits digital level sampling again；
Wherein, due to the continuous adjustment with reproduction ratio, the reproduction ratio particular image signal of generation is on flat panel TV
Display performance is exactly that black region constantly increases, and the color bits digital level sampled value of black is 0, therefore color bits is taken in this method
The value of digital level is 0 as discrimination standard；
C3. the value of the color bits digital level of the sampled point sampled again is checked, if its value is not still 0, is weighed
Multiple step C2, until the value sampling of the color bits digital level of last four sampled points is 0；
C4. it completes the reproduction ratio register value that output adjustment obtains after adjusting and data is set as reproduction ratio.
Compared with prior art, the present invention have it is below the utility model has the advantages that
In the method for the automatic carry out reproduction ratio adjustment of flat panel TV of the invention, by switching flat panel TV to accordingly
Information source determines flat panel TV requirement reproduction ratio further according to information source；Switching corresponding signal is required to fill according to information source and reproduction ratio
Set the corresponding desired specific dedicated processes signal of output (comprising possible standard or resolution requirement)；Believe according in respective image
Special setting adjustment reproduction ratio in number is arranged and is automatically write to be exported with data, the final reproduction ratio for realizing flat panel TV
Adjust automatically greatly improve the efficiency of image reproduction rate adjustment work simultaneously to realize the purpose that substitution manually adjusts
It can be used for flow line production.
