Description

A kind of method for making visual chart using color range legal system
Technical field：Present invention relates particularly to a kind of method for making visual chart using color range legal system.
Background technology：The vision testing method of world wide letter is designed according to the principle at visual angle at present：By extraneous 2 points The light sent, the angle formed through intraocular node.Under normal circumstances, human eye can tell the minimum range institute shape of point-to-point transmission Into visual angle be minimal visual angle, i.e. one point of visual angle.Visual chart is exactly to be designed in units of one point of visual angle.Referring to national standard GB 11533—1989。
By eye observation exterior object, it was observed that readability, the folder formed except foreign objects as node within the eye Outside angle, the readability positive correlation also with the image received by eyes, and readability is then to perceive image face by eyes The aberration size of color is distinguished.
The content of the invention：
Goal of the invention：It is an object of the invention to provide a kind of side that the visual chart to give a test of one's eyesight is made using aberration Method, and the method for making of aberration sight tester.
Technical scheme：
A kind of method for making visual chart using color range legal system, it is characterised in that：
In the method, if：
Bc (i) is the background color value of the i-th row sighting target on visual chart, i.e., paper or display face around the i-th row sighting target Colour；
Ec (i) is the color value of the i-th row sighting target on visual chart；
BcIr is the proportionality coefficient of visual chart often row Bc (i) changes；
Cd (i) is the value of chromatism of the i-th row sighting target on visual chart；
If Bc (i)=RGB (Bcr, Bcg, Bcb), Ec (i)=RGB (Ecr, Ecg, Ecb), then have following equation：
