STM32H743: image sensor trigger mode causes main loop to run slowly.

PY_H

The image sensor inputs a 24 MHz clock and outputs a 40 MHz clock, and the captured image size is 1280×1024×2. When the trigger mode of the image sensor is enabled, the main loop execution speed slows down by approximately 1.6 seconds; when the trigger mode is disabled, the system operates normally.
 
Furthermore, I intend to transmit the images collected by DCMI via USB, but these two modules cannot be enabled simultaneously. Additionally, when the DCMI is operating, serial port interrupts will cause abnormal operation of the DCMI.
 
How should I resolve this issue? Below is the configuration code and main loop code of my STM32H743:

Welcome to the forum.

You need to supply some more details - see: How to write your question to maximize your chances to find a solution.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
