The first image data includes image data or video data. The first data format data _ pattern is a data format of image data or video data. For example, the data format of the image data includes YUV4208bit, YUV42210bit, RAW12, and the like. Optionally, second image data may also be received, and a second data format of the received second image data may be determined. Here, the first image data is taken as an example.
In this embodiment, for example, the image data with the transmission data format YUV42210bit is taken as an example, the image data transmitted by DVP is received, and the first data format data _ pattern of the received image data is determined to be YUV42210 bit.
S120: and determining a target storage register set according to the first data format, and storing the first image data to the target storage register set.
The target register set comprises at least one storage register. In this embodiment, the storage space occupied by the target storage register group determined according to the first data format is smaller than the cache space determined according to the first data format.
For example, the buffer space determined according to the first data format YUV42210bit is 1920 × 1080 × 10 × 2bit, but in this embodiment, according to the first data format YUV42210bit, a target storage register group including 40 8-bit storage registers may be determined.
