以下是将 mipiraw10 的图像格式转换为 raw10 的图像格式的 C 代码:
```c
#include <stdio.h>
#include <stdlib.h>
void mipiraw10_to_raw10(unsigned char *mipi_buf, unsigned char *raw_buf, int width, int height);
int main() {
FILE *mipi_file, *raw_file;
int width = 640, height = 480;
unsigned char *mipi_buf = (unsigned char *) malloc(width * height * 5 / 4);
unsigned char *raw_buf = (unsigned char *) malloc(width * height * 10 / 8);
mipi_file = fopen("mipi.raw", "rb");
fread(mipi_buf, 1, width * height * 5 / 4, mipi_file);
fclose(mipi_file);
mipiraw10_to_raw10(mipi_buf, raw_buf, width, height);
raw_file = fopen("raw.raw", "wb");
fwrite(raw_buf, 1, width * height * 10 / 8, raw_file);
fclose(raw_file);
free(mipi_buf);
free(raw_buf);
return 0;
}
void mipiraw10_to_raw10(unsigned char *mipi_buf, unsigned char *raw_buf, int width, int height) {
int i, j;
int mipi_row_size = (width * 5 + 7) / 8;
int raw_row_size = (width * 10 + 7) / 8;
for (i = 0; i < height; i++) {
for (j = 0; j < width; j++) {
int byte_idx = (i * mipi_row_size) + (j * 5 / 8);
int bit_idx = (j * 5) % 8;
int mipi_val = ((mipi_buf[byte_idx] >> bit_idx) & 0x1F) << 5;
raw_buf[i * raw_row_size + j * 5 / 4] = mipi_val & 0xFF;
raw_buf[i * raw_row_size + j * 5 / 4 + 1] |= mipi_val >> 8;
}
}
}
```
这个代码示例读取名为 `mipi.raw` 的 mipiraw10 格式图像文件,将其转换为 raw10 格式并将结果存储到名为 `raw.raw` 的文件中。代码内部使用了 `mipiraw10_to_raw10` 函数来进行转换。
