Accordingly, the directional terminology is used for purposes of illustration and understanding, and is in no way limiting. In the drawings, elements having similar structures are denoted by the same reference numerals.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for recognizing a reading mode of an electronic device according to the present application.
The method for identifying the reading mode of the electronic equipment comprises the following steps:

For example, the data in x pixels of the k-th row is A1(R1、G1、B1)、A2(R2、G2、B2)、……、Ax(Rx、Gx、Bx)。
In the embodiment, i, n, k and x are positive integers, and k is more than or equal to 1 and less than or equal to n.
S20, acquiring the RGB data proportioning number of each line of pixels and the line number m of the RGB data proportioning number not more than 2 according to the RGB data of the n lines of pixels.

s201, acquiring first sub-pixel data of pixels in a k line of the n lines of pixels;
in the step, the first sub-pixel in a certain row of pixels in the n rows of pixels is mainly used as a research object. The first subpixel may be at least one of red subpixel data, green subpixel data, or blue subpixel data.
For example, in step S10, the data of the red sub-pixel in the x pixels of the k-th row is a1(R1)、A2(R2)、……、Ax(Rx)。
S202, when the pixels in the kth row comprise at most one first sub-pixel data different from the rest first sub-pixel data in the kth row, the first sub-pixels of the pixels in the kth row meet the data proportion of a reading mode; otherwise, the target electronic equipment is in a non-reading mode, and the display brightness of the target electronic equipment is kept unchanged;
the method is mainly used for judging the matching type of the first sub-pixel data in the k-th row of pixels. For example, R is randomly selected1And R2When R1 is equal to R2, and R1, R2, R … …, and Rx are equal to each other, the red sub-pixels in the k-th row of pixels have only one data allocation, and the data allocation of the reading mode of the target electronic device is satisfied. When R1 is not equal to R2, whether the values of R3, R4, … …, Rx and R1 or R2 are equal is judged, if the values of R3, R4, … …, Rx and R1 or R2 are equal, the red sub-pixels in the kth row of pixels have only two data ratios, and the data ratio of the reading mode of the target electronic equipment is met. If more than one of R3, R4, … … and Rx is not equal to the value of R1 or R2, the data matching type of the red sub-pixels in the k-th row of pixels exceeds 2, the data matching of the reading mode of the target electronic equipment is not met, the target electronic equipment is in the non-reading mode, and the display brightness of the target electronic equipment is kept unchanged.

S1＝R1+G1+B1；
S2＝S2+G2+B2；
S3＝R3+G3+B3；
And obtaining whether S1, S2 and S3 are equal or the numerical value type number of S according to the sum. If S1, S2 and S3 are all equal, the number of S types is 1; if S1 ≠ S2 ≠ S3, then the number of species of S is 2; if S1 ≠ S2 ≠ S3, the number of classes of S is 3.

M2＝S2*G2*B2；
M3＝R3*G3*B3；
And obtaining whether the M1, the M2 and the M3 are equal or the number of the numerical value types of the M according to the sum. If M1, M2 and M3 are all equal, the number of M types is 1; if M1 ≠ M2 ≠ M3, then the number of M classes is 2; if M1 ≠ M2 ≠ M3, the number of M classes is 3.
S205, when the number of the types of any one of the pixels S, M in the k row exceeds 2, the target electronic equipment is in a non-reading mode, and the display brightness of the target electronic equipment is kept unchanged; otherwise, the data proportion of the k row of pixels meeting the reading mode is obtained;
s206, repeating the steps S201 to S205, and obtaining the RGB data proportioning type number of each line of pixels in the n lines of pixels and the line number m of which the RGB data proportioning type number is not more than 2.
That is, the RGB data matching type of the target line pixel in the ith frame is obtained according to step S20. To determine whether the ith frame is in a reading mode.
S30, when the ratio of m to n is larger than a first threshold, the target electronic equipment is in a reading mode, and the display brightness of the target electronic equipment is reduced; and when the ratio of m to n is smaller than a first threshold, the target electronic equipment is in a non-reading mode, and the display brightness of the target electronic equipment is kept unchanged.
In this embodiment, the first threshold is a set value, and may be obtained according to a specific experiment, which is not limited in this application.
S40, acquiring RGB data of any n lines of pixels in the (i + 1) th to (i + j) th frame pictures of the target electronic equipment, wherein j is larger than 1 and is a positive integer;
