Panoramic Camera Brightness Compensation via Dynamic Exposure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic cameras with multiple lenses often produce videos with inconsistent brightness due to differences in lighting conditions, leading to reduced viewing experience for users.
Innovation Solution
An image processing method that continuously acquires and analyzes frames from a camera, applying brightness compensation based on a threshold range to ensure consistent image brightness, adjusting exposure settings as needed to match the shooting environment.

If multiple cameras are used for panoramic shooting, then the field of view and coverage are improved, but brightness inconsistency and color differences occur due to varying lighting conditions and camera characteristics
Solution Approach 1:
The patent applies parameter changes by adjusting exposure time, gain, and brightness compensation parameters for each camera based on measured brightness values. The system dynamically modifies these parameters to ensure consistent brightness across all cameras in the panoramic setup, resolving the brightness inconsistency issue while maintaining the extended field of view.
Solution Approach 2:
The patent implements feedback mechanisms by continuously measuring the brightness output of each camera and using this information to adjust exposure and compensation parameters. This closed-loop control ensures that brightness inconsistencies are detected and corrected in real-time, maintaining uniform illumination across the panoramic view.

If brightness compensation is applied to improve viewing experience, then image brightness is improved, but processing time and computational complexity increase
Solution Approach 1:
The patent applies preliminary action by measuring the brightness characteristics of each camera before panoramic shooting begins and pre-calculating the necessary compensation parameters. This allows the system to apply brightness compensation without adding significant processing time during actual shooting, as the correction parameters are prepared in advance.
Solution Approach 2:
The system optimizes processing efficiency by making parameter changes to exposure time and gain settings before image capture, rather than performing complex post-processing adjustments. This preventive approach to brightness management reduces computational burden and processing time while achieving the desired brightness improvement.

AI summary
Disclosed are an image processing method, an image processing apparatus, an electronic device, and a storage medium. The method includes: when a camera continuously outputs original images, a first frame image output by the camera is acquired; it is determined whether to perform a brightness compensation on the camera according to a brightness value of the first frame image and a brightness threshold range; and it is repeatedly continued to acquire an image to be measured output by the camera after a preset time interval and determined whether to perform the brightness compensation on the camera according to a brightness value of the image to be measured and the brightness threshold range, until the camera stops outputting the original images.
