Innovation Solution
An image display apparatus with a communication unit, image synthesizing unit, projection unit, functional mode management unit, image capture device, designated screen image recognition unit, and signal control unit, which allows for multi-segmented screen image projection and hand movement recognition to manage active and non-active image data transmission based on operator input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communication function is employed to communicate with multiple PCs simultaneously, then the need for multiple input terminals is eliminated, but the data size received increases and communication processing load increases
Solution Approach 1:
The patent implements dynamic communication status management where the image display apparatus can switch between active and non-active communication states for each connected PC. The functional mode management unit controls whether to receive or ignore interrupt requests from each PC based on current operation mode, allowing the system to adaptively manage communication load rather than continuously processing all incoming data.
Solution Approach 2:
The patent segments the communication management by dividing connected PCs into different groups based on their communication status (active or non-active). The functional mode management unit independently controls communication reception for each PC, allowing selective processing of interrupt requests and image data from specific PCs while ignoring others, thereby reducing overall processing load.
2Adaptability or versatility
If interrupt requests are received from all connected PCs in normal projection mode, then communication flexibility is maintained, but communication processing load increases
Solution Approach 1:
The system dynamically adjusts its communication behavior based on the operational mode. In normal projection mode, the functional mode management unit receives interrupt requests from all connected PCs maintaining full communication flexibility. In multi-segmented screen operation mode, it selectively ignores interrupt requests from PCs not designated for active status, thereby improving processing efficiency while maintaining adaptability when needed.
3Ease of operation
If multi-segmented screen operation mode is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The image capture device automatically captures images of the projected screen and the operator's hand movements without requiring manual intervention. The designated screen image recognition unit automatically recognizes which screen image the operator intends to activate based on captured hand movement images, eliminating the need for complex manual mode switching operations while maintaining simple user interaction.
Solution Approach 2:
The patent replaces manual mechanical mode switching with automated image recognition and processing. Instead of requiring operators to manually configure multi-segmented screen modes through complex settings, the system uses the image capture device and designated screen image recognition unit to automatically detect operator intent through hand movement recognition and switch modes accordingly.

AI summary
An image display apparatus includes a communication unit to communicate with information processing apparatuses; an image synthesizing unit to synthesize a multi-segmented screen image composed of screen images of the information processing apparatuses; a projection unit to project the multi-segmented screen image onto a screen; a functional mode management unit to control switching between a normal projection mode and a multi-segmented screen operation mode; an image capture device to capture the multi-segmented screen image and a hand movement of an operator when switched to the multi-segmented screen operation mode; a designated screen image recognition unit to detect a hand movement of the operator based on the image captured by the image capture device, and to recognize a screen image designated as an active-target image; and a signal control unit to transmit a request of image data transmission to an information processing apparatus corresponding to the designated active-target image.
