Image Display Apparatus Pattern-Based External Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems require complex network setups and special control systems for external devices to change settings, making it inconvenient for users to operate devices remotely or from a distance without a familiar remote controller.
Innovation Solution
An image display apparatus and system that includes an image reception unit, display unit, setting changing unit, image determination unit, and control unit, which allows external devices to generate and superimpose a prescribed pattern onto image data, enabling setting changes without a special command control system by detecting predefined patterns within the image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a command control system is constructed using RS-232C or Ethernet to enable external devices to change settings, then the external device can directly control the image display apparatus, but the system becomes very complicated especially when multiple external devices with different connection methods are connected
Solution Approach 1:
The patent replaces the mechanical/electrical command control system (RS-232C, Ethernet) with an optical control system. External devices capture images containing control commands using imaging functions, and the image display apparatus detects these commands by analyzing the captured images. This substitution eliminates the need for complex network infrastructure and special control systems, allowing any device with imaging capability to control the display apparatus through simple image transmission.
2Ease of operation
If direct operation of the image display apparatus or use of a remote controller is used to change images, then the operation can be performed immediately, but it is not convenient for users of external devices installed in a place apart from the image display apparatus
Solution Approach 1:
The patent makes the image display apparatus universally controllable by any external device with imaging capability. The apparatus detects control commands from images captured by various external devices (smartphones, tablets, cameras, etc.) without requiring device-specific control systems. This multi-functional approach allows remote operation from any location while maintaining ease of use, as the control method remains consistent regardless of the external device type.
3Extent of automation
If a special system for command control is constructed to enable external devices to change settings, then the external device can directly perform operations, but it requires constructing a network in advance and creates a complicated system especially when multiple connection methods are used
Solution Approach 1:
The patent enables the image display apparatus to autonomously detect and execute control commands from images without requiring a pre-configured control system. The apparatus automatically analyzes received images to identify control commands, determines the appropriate settings changes, and executes them autonomously. This self-service capability eliminates the need for complex network construction and system configuration, allowing automatic setting changes through simple image transmission.

AI summary
An image display apparatus includes an image reception unit that receives image data from an external device, a display unit that displays an image related to the image data, a setting changing unit that changes, in accordance with an instruction determined in advance, a setting determined in advance, an image determination unit that determines whether or not a prescribed pattern determined in advance is included in the image related to the image data, a storage unit that holds the instruction in association with the prescribed pattern in advance, and a control unit that, when the image determination unit determines that the prescribed pattern is included in the image related to the image data, causes the setting changing unit to change the setting in accordance with the instruction associated with the prescribed pattern.
