For example, first image brightness matrix data a is calculated according to the partition capability data of the chip, where the first image brightness matrix data a reflects the image brightness data of the image information under the partition capability data of the chip. Then, the backlight partition data of the terminal device is obtained, the backlight partition data reflect the actual partition data of the terminal device, then the first image brightness matrix data A is converted based on the actual partition data to obtain image brightness conversion matrix data B, the image brightness conversion matrix data B is obtained based on the actual partition data of the terminal device and the first image brightness matrix data A, so that in the process of obtaining the image brightness conversion matrix data B, the powerful partition capacity of a chip is used, the accuracy of the obtained image brightness conversion matrix data B is higher, for this reason, the image brightness matrix data C can be determined based on the image brightness conversion matrix data B, and the image brightness matrix data C reflect the actual brightness data of the terminal device, so that the terminal device can perform the brightness control of the backlight partition based on the image brightness matrix data C.
Exemplary method
The backlight partition brightness control method in the embodiment can be applied to terminal equipment, and the terminal equipment can be intelligent terminal equipment such as televisions, computers and mobile phones. Specifically, as shown in fig. 1, the backlight partition luminance control method in the present embodiment includes the steps of:
step 100, obtaining partition capacity data corresponding to a chip, and processing image information according to the partition capacity data to obtain first image brightness matrix data corresponding to the partition capacity data.
The partition capability data obtained in this embodiment refers to the limit partition capability corresponding to the chip, and in general, the computing power of the chip can obtain thousands of partitions. After the partition capability data is obtained, the embodiment can process the image information by using the partition capability data, so as to obtain first image brightness matrix data corresponding to the partition capability. In this case, the first image luminance matrix data is luminance data obtained when image information is processed directly by using high computation power of the chip.
In one implementation, the method includes the following steps when obtaining the first image brightness matrix data:
step S101, obtaining partition capacity data of the chip, wherein the partition capacity data comprises first transverse partition data and first longitudinal partition data;
step S102, processing the image information based on the first transverse partition data and the first longitudinal partition data, and calculating to obtain first image brightness matrix data of the image information under the partition capacity data.
In particular, the partition capability data of this embodiment includes first horizontal partition data and first vertical partition data, denoted as aXb (note: X is not a multiplier for interval, and the multi-partition backlight is generally identified by the number of partitions in both horizontal and vertical directions). Where a is the first transverse partition data and b is the first longitudinal partition data. When the image information is processed by using the partition capability data, the first image brightness matrix data is obtained and expressed as
Wherein Lxy is the brightness of the x-th lateral and y-th longitudinal partition. Therefore, the brightness data of each backlight partition under the high calculation power of the chip can be obtained according to the first image brightness matrix data.
Step 200, acquiring backlight partition data, and performing data conversion processing on the first image brightness matrix data according to the backlight partition data to obtain image brightness conversion matrix data.
In this embodiment, the backlight partition data refers to partition data reflecting actual partition data of the terminal device, and in general, the partition capability of the chip is larger than the partition capability acceptable by the terminal device itself, so the backlight partition data in this embodiment is smaller than the partition capability data of the chip. After the first image brightness matrix data is obtained, the first image brightness matrix data is brightness data obtained by using high computing power of a chip and cannot be directly applied to the terminal equipment, and data conversion processing is performed on the first image brightness matrix data to obtain image brightness conversion matrix data, wherein the image brightness conversion matrix data is favorable for determining actual image brightness matrix data of the terminal equipment in subsequent steps.
In one implementation, the method in determining the image brightness conversion matrix data includes the following steps:
step S201, acquiring the backlight partition data to obtain transverse backlight partition data and longitudinal backlight partition data;
step S202, performing data conversion processing on the first image brightness matrix data according to the first horizontal partition data, the first vertical partition data, the horizontal backlight partition data and the vertical backlight partition data, so as to obtain the image brightness conversion matrix data.
In the implementation, since the partition capacity of the chip is larger than the partition capacity acceptable by the terminal device, the lateral backlight partition data and the vertical backlight partition data are obtained after the backlight partition data are obtained in the embodiment. Wherein the lateral backlight partition data is smaller than the first lateral partition data and the longitudinal backlight partition data is smaller than the first longitudinal partition data. In this embodiment, the backlight partition data of the terminal device is cXd, c is the horizontal axis backlight partition data, d is the vertical axis backlight partition data, and the image brightness matrix is
ZxyThe brightness of the x-th horizontal and y-th vertical partition. In order to convert the first image brightness matrix data into the terminal device image brightness matrix data, in this embodiment, after obtaining the backlight partition data, a first ratio between the horizontal backlight partition data and the first horizontal partition data, that is, a/c, and a second ratio between the vertical axis backlight partition data and the first vertical partition data, that is, b/d, are respectively obtained. Then substituting the first ratio and the second ratio into the first image brightness matrix data to obtain the image brightness conversion matrix data, which is expressed as +.>
The image brightness conversion matrix data is obtained based on the actual partition data of the terminal equipment and the first image brightness matrix data, so that the powerful partition capacity of the chip is used in the process of obtaining the image brightness conversion matrix data, and conditions are provided for obtaining more accurate image brightness matrix data in the subsequent steps.
In this embodiment, after the image brightness conversion matrix data is obtained, in step S300, according to the image brightness conversion matrix data, image brightness matrix data corresponding to the backlight partition data is obtained, and according to the image brightness matrix data, the brightness data of the backlight partition is controlled.
The image brightness matrix data can be determined according to the image brightness conversion matrix data, and the image brightness matrix data reflects the actual brightness data of the terminal equipment, so that the terminal equipment can control the brightness data of the backlight partition according to the image brightness matrix data. Because the image brightness conversion matrix data is obtained based on the actual partition data of the terminal equipment and the first image brightness matrix data, in the process of obtaining the image brightness conversion matrix data, the powerful partition capacity of a chip is used, the obtained image brightness conversion matrix data has higher precision, the more accurate image brightness matrix data can be determined based on the image brightness conversion matrix data, and the image brightness matrix data reflects the actual brightness data of the terminal equipment, so that the terminal equipment can perform the brightness control of backlight partition based on the image brightness matrix data.
In one implementation manner, the step S300 specifically includes the following steps:
step S301, a preset weight matrix is obtained, and the duty ratio of the first image brightness matrix data in the image brightness conversion matrix data is adjusted according to the weight matrix, so that the image brightness matrix data is obtained;
step S302, controlling the brightness data of the backlight subareas according to the image brightness matrix data.
In practical implementation, this embodiment sets a weight matrix expressed as
0≤n xy Not more than 1, equal to and%>
n xy For the coefficients for adjusting the duty ratio of the first image luminance matrix data in the image luminance conversion matrix data, settings may be adapted by the user, e.g. +.>
Therefore, the weight matrix in this embodiment is used to adjust the duty ratio of the first image brightness matrix data in the image brightness conversion matrix data, and when the specific application is performed, the weight matrix is substituted into the image brightness conversion matrix data, so that the image brightness matrix data can be obtained. For example, a->
The image brightness matrix data can be calculated>
Finally, the terminal device can control the brightness of the backlight partition based on the image brightness matrix data.
In summary, the present embodiment first obtains partition capability data corresponding to a chip, and processes image information according to the partition capability data to obtain first image brightness matrix data corresponding to the partition capability data; acquiring backlight partition data, and performing data conversion processing on the first image brightness matrix data according to the backlight partition data to obtain image brightness conversion matrix data; and obtaining image brightness matrix data corresponding to the backlight partition data according to the image brightness conversion matrix data, and controlling the brightness data of the backlight partition according to the image brightness matrix data.
