Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform luminance control is applied to all content based on viewing environment brightness, then the control system is simple and easy to implement, but optimal image output cannot be achieved for different programs and scenes
Solution Approach 1:
The patent segments the content into different programs and scenes, applying distinct luminance control algorithms to each. The luminance control is divided into program-unit control and scene-unit control, allowing different control strategies for different content types while maintaining system manageability through modular algorithm selection.
Solution Approach 2:
The system dynamically selects and switches between different luminance control algorithms based on the detected program type and scene characteristics. The control algorithm changes adaptively according to the content being displayed, transitioning between uniform control, program-specific control, and scene-specific control as needed.
2Manufacturing precision
If different signal conversion algorithms are applied in program units or scene units, then optimal image output for specific content is achieved, but the device complexity increases
Solution Approach 1:
The patent implements a universal luminance control system that can perform multiple functions: uniform luminance control for all content, program-specific luminance control, and scene-specific luminance control. This multi-functional approach allows the same hardware platform to handle diverse control requirements without requiring separate dedicated systems for each control mode.
Solution Approach 2:
The system automatically detects program types and scene characteristics using embedded sensors and algorithms, then self-selects the appropriate luminance control strategy without requiring manual configuration. The control system serves itself by autonomously adapting to different content types, reducing the burden on users and simplifying operation despite the underlying complexity.

AI summary
To provide an apparatus and method for executing signal conversion processing according to environmental light in a content unit, a scene unit, or a frame unit to generate an output image. Provided is an image display control apparatus including a data processing unit that controls image signals to be output to a display unit, the data processing unit being configured to execute a display control application supporting a content to be displayed on the display unit to generate output image signals. The data processing unit inputs sensor detection signals from a sensor that acquires environmental light information in a periphery of the display unit, and applies the sensor detection signals and generates output image signals by carrying out signal conversion processing in which different signal conversion algorithms are applied to original input image signals of the content in a content unit, a unit of scenes configuring a content, or a frame unit.
