RT1050 Use PXP Convert image by YUV422 to RGB565

shawn_chai — Mon, 18 Mar 2019 15:39:38 GMT

I use pxp convert image by YUV422 to RGB565, YUV422 from camera ,so we set psBufferConfig.pixelFormat the value has

kPXP_PsPixelFormatRGB888 = 0x4, /*!< 32-bit pixels without alpha (unpacked 24-bit format) */
kPXP_PsPixelFormatRGB555 = 0xC, /*!< 16-bit pixels without alpha. */
kPXP_PsPixelFormatRGB444 = 0xD, /*!< 16-bit pixels without alpha. */
kPXP_PsPixelFormatRGB565 = 0xE, /*!< 16-bit pixels without alpha. */
kPXP_PsPixelFormatYUV1P444 = 0x10, /*!< 32-bit pixels (1-plane XYUV unpacked). */
kPXP_PsPixelFormatUYVY1P422 = 0x12, /*!< 16-bit pixels (1-plane U0,Y0,V0,Y1 interleaved bytes) */
kPXP_PsPixelFormatVYUY1P422 = 0x13, /*!< 16-bit pixels (1-plane V0,Y0,U0,Y1 interleaved bytes) */
kPXP_PsPixelFormatY8 = 0x14, /*!< 8-bit monochrome pixels (1-plane Y luma output) */
kPXP_PsPixelFormatY4 = 0x15, /*!< 4-bit monochrome pixels (1-plane Y luma, 4 bit truncation) */
kPXP_PsPixelFormatYUV2P422 = 0x18, /*!< 16-bit pixels (2-plane UV interleaved bytes) */
kPXP_PsPixelFormatYUV2P420 = 0x19, /*!< 16-bit pixels (2-plane UV) */
kPXP_PsPixelFormatYVU2P422 = 0x1A, /*!< 16-bit pixels (2-plane VU interleaved bytes) */
kPXP_PsPixelFormatYVU2P420 = 0x1B, /*!< 16-bit pixels (2-plane VU) */
kPXP_PsPixelFormatYVU422 = 0x1E, /*!< 16-bit pixels (3-plane) */
kPXP_PsPixelFormatYVU420 = 0x1F, /*!< 16-bit pixels (3-plane) */

the camera parameter only have YCbCr 422.

So I should choose which one.

Hi,

Please help to provide the camera datasheet.

Then we can select the correct ps buffer format.

Have a great day,
Mike

Hi,

Thank you for the info.

Please select below format value:

kPXP_PsPixelFormatUYVY1P422 = 0x12, /*!< 16-bit pixels (1-plane U0,Y0,V0,Y1 interleaved bytes) */

Wish it helps.

Have a great day,
Mike
