Camera Module Area Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules struggle to adjust image brightness effectively, as they typically adjust the entire image's brightness rather than allowing users to control brightness in specific areas, making it inconvenient to achieve desired brightness levels in particular regions.
Innovation Solution
A camera module with a controller that outputs shutter speed control signals to adjust the brightness of selected areas, allowing users to set reference brightness for specific areas or the entire image, and automatically adjust exposure based on differences between the selected areas' brightness and the reference brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera module adjusts brightness based on the entire image, then the overall brightness is controlled, but the brightness of specific particular areas cannot be adjusted independently
Solution Approach 1:
The display unit is divided into multiple divided areas, and the controller selects specific particular areas from these divided areas to calculate average brightness. This segmentation allows independent brightness control of selected areas rather than treating the entire image uniformly, resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The patent applies local quality by enabling brightness adjustment for specific particular areas while maintaining different brightness levels in other areas. The controller calculates average brightness only for selected particular areas and uses this to adjust shutter speed, creating localized brightness control that improves both user convenience and flexibility.
2Ease of operation
If the camera module allows manual brightness adjustment, then user control is improved, but the complexity of the control system increases
Solution Approach 1:
The controller automatically calculates the average brightness of selected particular areas and autonomously adjusts the shutter speed without requiring complex manual input from the user. The system serves itself by processing brightness data and generating appropriate control signals, simplifying the user interface while maintaining sophisticated control capabilities.
Solution Approach 2:
The controller continuously monitors the brightness of selected particular areas and uses this feedback to adjust shutter speed dynamically. This feedback mechanism allows the system to adapt to different lighting conditions and user selections automatically, improving ease of operation while keeping the control logic streamlined through automated response.

AI summary
The present invention relates to a camera module and a method for driving the camera module, the module including: a photographing unit controlling a shutter speed to photograph an image in response to an inputted control signal; a display unit displaying the image; and a controller outputting a first shutter speed control signal to the photographing unit to allow an average brightness of two or more particular areas to become a set reference brightness, in a case the two or more particular areas in a plurality of divided areas in the display unit are selected.
