Initial value is less than the current value of x coordinate, and the initial value of y-coordinate is greater than the current value of y-coordinate, the first grayscale by reducing blue
Value is to increase the coordinate value of y-coordinate so that being equal or close to initial value, it is assumed that available according to the second corresponding relationship
Following relationship: the offset that blue grayscale value reduces a step-length (grayscale value 1) then y-coordinate is Δ y1, then can be according to Δ
The initial offset of y1 and y-coordinate determine the size for the grayscale value that blue should reduce, i.e., blue corresponding color compensation
Value.
Offset due to will lead to x coordinate while adjustment blue increases, then may further be corresponding according to blue
The initial offset of color compensation value and the x coordinate determines the final offset of the x coordinate, and then according to above-mentioned original
Reason determines red corresponding color compensation value, and adjusting red grayscale value only influences the offset of x coordinate.Assume according to the
The available following relationship of three corresponding relationships: the offset that red grayscale value reduces a step-length (grayscale value 1) then x coordinate is
Δ x1 then can determine the size for the grayscale value that red should reduce according to the final offset of Δ x1 and x coordinate, i.e., red
The corresponding color compensation value of color.

The grayscale value for reducing blue is first passed through to increase the coordinate value of x coordinate so that being equal or close to initial value, it is assumed that according to
The available following relationship of 4th corresponding relationship: blue grayscale value reduces the offset of a step-length (grayscale value 1) then x coordinate
For Δ x2, then the size for the grayscale value that blue should reduce can be determined, i.e., according to the initial offset of Δ x2 and x coordinate
The corresponding color compensation value of blue.
Offset due to will lead to y-coordinate while adjustment blue increases, then may further be corresponding according to blue
The initial offset of color compensation value and the y-coordinate determines the final offset of the y-coordinate, and then according to above-mentioned original
Reason determines the corresponding color compensation value of green, and the grayscale value for adjusting green only influences the offset of y-coordinate.Assume according to the
The available following relationship of five corresponding relationships: the offset that green grayscale value reduces a step-length (grayscale value 1) then y-coordinate is
Δ y2 then can determine the size for the grayscale value that green should reduce according to the final offset of Δ y2 and y-coordinate, i.e., green

Target initial offset and third corresponding relationship determine red corresponding color compensation value；According to the initial inclined of the y-coordinate
Shifting amount and the 5th corresponding relationship determine the corresponding color compensation value of green.
Specifically, if the initial offset of x coordinate is greater than 0, the initial offset of the y-coordinate is greater than 0, i.e. x coordinate
Initial value is less than the current value of x coordinate, and the current value that the initial value of y-coordinate is less than y-coordinate is determined then according to above-mentioned principle
Red corresponding color compensation value, adjusting red grayscale value only influences the offset of x coordinate.Assume according to third corresponding relationship
Available following relationship: the offset that red grayscale value reduces a step-length (grayscale value 1) then x coordinate is Δ x1, then may be used
To determine the size for the grayscale value that red should reduce, i.e., red corresponding color according to the final offset of Δ x1 and x coordinate
Color offset.According to above-mentioned principle, the corresponding color compensation value of green is determined, the grayscale value for adjusting green only influences y-coordinate

Amount and the second corresponding relationship determine the corresponding color compensation value of blue；
According to the corresponding color compensation value of the blue and the initial offset of the x coordinate, the x coordinate is determined
Final offset；
If the final offset of the x coordinate is greater than 0, closed according to the final offset and third of the x coordinate are corresponding

According to the corresponding new color compensation value of the blue, the new offset of the y-coordinate is determined；
According to the new offset and the 5th corresponding relationship of the y-coordinate, the corresponding color compensation value of green is determined.
Specifically, the initial offset of the y-coordinate is less than 0, i.e. x coordinate if the initial offset of x coordinate is less than 0

Offset due to will lead to x coordinate while adjustment blue increases, then may further be corresponding according to blue
The initial offset of color compensation value and the x coordinate determines the final offset of the x coordinate, initial due to x coordinate
Whether offset then further judges the final offset of the x coordinate still less than 0 less than 0.
If the final offset of x coordinate is greater than 0, directly adjustment is red, and according to above-mentioned principle, it is red right to determine
The color compensation value answered, adjusting red grayscale value only influences the offset of x coordinate.Assume to be obtained according to third corresponding relationship
To following relationship: the offset that red grayscale value reduces a step-length (grayscale value 1) then x coordinate is Δ x1, then can basis
