Solution Overview

Problem

Existing display control methods require complex operations to switch between modes like move, vivid, and game modes, leading to inconvenience and longer time consumption.

Innovation Solution

A display system that uses a camera to capture hand images, determines the number of fingers through feature points, and adjusts display settings and external device controls based on finger counts to simplify mode switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional display control methods are used to switch between modes, then display mode switching is achieved, but operation complexity increases and time consumption increases

Engineering Contradiction:

Improvedisplay mode switching operationVSAvoidtime consumption for mode switching

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical or manual control methods with an optical recognition system. The camera captures hand images, and the processor analyzes finger configurations to automatically determine display modes, substituting manual mode selection with automated optical recognition and image processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service operation where the display automatically adjusts its mode based on recognized hand gestures. The processor autonomously interprets finger configurations and switches display modes without requiring user intervention or complex control inputs, making the system serve itself in response to simple gestures.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If multiple display modes are supported, then display versatility improves, but operation complexity increases

Engineering Contradiction:

Improvedisplay mode varietyVSAvoidcontrol operation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal control mechanism where a single hand gesture recognition system handles multiple display modes. Different finger configurations (such as different numbers of extended fingers or specific hand shapes) correspond to different display modes, allowing one system to perform multiple functions of mode selection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses parameter changes in hand gesture recognition to control display modes. By detecting variations in finger configuration parameters (number of fingers extended, which fingers are bent, hand orientation), the system translates these physical parameters into corresponding display mode parameters, enabling versatile control through simple parameter variations.

Inventive Principle:

Principle #35Parameter changes

AI summary

A display includes a processor, a display module, a camera and a storage device. The display module is coupled to the processor. The camera is coupled to the processor, and configured to capture an image of a hand to generate a hand image. The storage device is coupled to the processor, and stores one or a plurality of program codes. When the processor reads and executes the code(s), at least following steps are performed: determining a number of finger(s) appeared in the hand image according to multiple feature points of the hand image; and determining, according to a value of the number of finger(s), to perform at least one of two operations in following: performing a preset operation to the display and generating a control signal, in which the control signal is configured for controlling an external device.
