Image Display Apparatus Self-Detecting Spotlight Region

Solution Overview

Problem

Existing image display apparatuses require a separate program and communication interface IC to highlight a sub-screen region, increasing costs and power consumption.

Innovation Solution

An image display apparatus that self-analyzes image data to detect and highlight a predetermined region by converting RGB image data to YUV format, analyzing for moving images, adjusting brightness, and converting back to RGB for display, eliminating the need for external coordinate data and separate ICs.

1Ease of operation

If a separate communication interface IC and coordinate data input method are used to highlight a sub-screen region, then the spotlight function can be implemented, but fabrication costs and device complexity increase

Engineering Contradiction:

Improvespotlight functionVSAvoidseparate IC and coordinate data input

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the spotlight function with the existing image processing circuitry. The image processing unit that normally processes display images is enhanced to also perform region detection and brightness adjustment for spotlighting, eliminating the need for separate ICs and coordinate data input interfaces.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display device performs self-detection of the region to be highlighted by analyzing image data received from the external device. The system automatically identifies the sub-screen region and adjusts its brightness without requiring external coordinate data or separate control ICs, making the system self-sufficient.

Inventive Principle:

Principle #25Self-service
