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);
