• Input image resolution and format:
  • If the input image resolution is within the range of [10 x 6, 4096 x 4096], the input image format described in Restrictions on Image Formats, Width and Height Alignment, and Buffers is supported.
  • When the width or height of the input image is within the range of (4096, 8192], the supported formats are as follows:
    The following enumerated values of hi_pixel_format are supported:

    HI_PIXEL_FORMAT_YUV_400 = 0,               // YUV400 8bit
    HI_PIXEL_FORMAT_YUV_SEMIPLANAR_420 = 1,    // YUV420SP NV12 8bit   
    HI_PIXEL_FORMAT_YVU_SEMIPLANAR_420 = 2,    // YUV420SP NV21 8bit 
    HI_PIXEL_FORMAT_YUV_SEMIPLANAR_422 = 3,    // YUV422SP 8bit
    HI_PIXEL_FORMAT_YVU_SEMIPLANAR_422 = 4,    // YVU422SP 8bit
    HI_PIXEL_FORMAT_YUV_SEMIPLANAR_444 = 5,    // YUV444SP 8bit
    HI_PIXEL_FORMAT_YVU_SEMIPLANAR_444 = 6,    // YVU444SP 8bit
    HI_PIXEL_FORMAT_YUYV_PACKED_422 = 7,       // YUV422Packed YUYV 8bit
    HI_PIXEL_FORMAT_UYVY_PACKED_422 = 8,       // YUV422Packed UYVY 8bit
    HI_PIXEL_FORMAT_YVYU_PACKED_422 = 9,       // YUV422Packed YVYU 8bit
    HI_PIXEL_FORMAT_VYUY_PACKED_422 = 10,      // YUV422Packed VYUY 8bit

  • For details about the restrictions on the width and height alignment and buffer size of each image format, see Restrictions on Image Formats, Width and Height Alignment, and Buffers.
• For details about the restrictions on the output image resolution, image format, width and height alignment, and buffer size, see Restrictions.
• Processing a single 1080p image requires a recommended setting of 3 ms timeout, and two 1080p images require a recommended setting of 6 ms timeout. This rule applies to more images. In terms of resolution, a 4K image is equivalent to four 1080p images, and therefore processing a single 3840 x 2160 image requires a recommended setting of 12 ms timeout.
