STM32F4,DCMI_OV9655_SelectOutputFormat

Posted on April 21, 2017 at 00:02

I am using the ov9655 camera for image processing with the STM32F4 microprocessor.  I want to convert the camera format from RGB to YUV(grayscala) . How can ı do it ?

/* OV9655 Camera size setup */

#if defined (QQVGA_SIZE)

DCMI_OV9655_QQVGASizeSetup();

#elif defined (QVGA_SIZE)

DCMI_OV9655_QVGASizeSetup();

#endif

/* Set the RGB565 mode */

DCMI_SingleRandomWrite(OV9655_DEVICE_WRITE_ADDRESS, OV9655_COM7, 0x63);

DCMI_SingleRandomWrite(OV9655_DEVICE_WRITE_ADDRESS, OV9655_COM15, 0xd0);

/* Invert the HRef signal*/

DCMI_SingleRandomWrite(OV9655_DEVICE_WRITE_ADDRESS, OV9655_COM10, 0x08);

/* OV9655 Camera DCMI setup */

OV9655_DCMI_Configuration();

return (0x00);
