Hello @Arun_1612 and welcome to the Community :),

I recommend you the DCMI_CaptureMode example as a reference code.

This example describes how to use the DCMI to interface with a camera module and continuously capture images to a Camera Frame Buffer located in external SDRAM. Each camera image is then copied to the LCD display frame buffer using the DMA2D in ARGB8888 format.

Also, the AN5020 Introduction to digital camera interface (DCMI) for STM32 MCUs can help you to use the DCMI.

This application note gives to the STM32 users some basic concepts, with easy-to-understand explanations of the features, architecture, and configuration of the DCMI. It is supported by an extensive set of detailed examples. These examples are shared in 8.3 DCMI examples based on STM32CubeMX section can help you to capture and display of RGB data.
