Solution Overview
Problem
Existing position detection systems, such as those using infrared light sources and image pickup devices, do not effectively utilize the distance between the input device and imaging targets for input operations, leading to interference with precise operation inputs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the image pickup device and imaging targets is used for adjustment only, then the position detection system can function, but the operation precision is interfered with and flexibility is limited
Solution Approach 1:
The patent applies dynamics by making the display image size change dynamically based on the distance between the input device and imaging targets. The system continuously updates the display image size as the distance changes, transforming a static display into a dynamic one that responds to user movement, thereby enabling flexible operations like grabbing and rotating images intuitively
Solution Approach 2:
The patent changes the display image size parameter based on the distance parameter. By establishing a relationship between distance (obtained from target image data) and display image size, the system enables versatile operations such as enlargement, reduction, grabbing, and rotating of display images, transforming the distance parameter from a mere adjustment value into a control parameter for multiple operations
2Ease of operation
If the distance between input device and imaging targets changes, then operational flexibility increases, but precise operation inputs are interfered with
Solution Approach 1:
The patent implements feedback by continuously obtaining target image data that reflects the current distance between the input device and imaging targets, and using this feedback to adjust the display image size accordingly. This closed-loop feedback mechanism ensures that the display image size always corresponds to the actual distance, maintaining operation precision while enabling flexibility
Solution Approach 2:
The patent replaces traditional mechanical operation mechanisms (buttons, joysticks) with a vision-based distance detection system. By using the image pickup device to capture target images and calculate distance, the system substitutes mechanical input methods with optical measurement, thereby improving both flexibility and precision simultaneously

AI summary
Predetermined image processing is performed in accordance with an input operation performed by an input device having image pickup means for taking an image of one or a plurality of imaging targets. Target image data, which is obtained from one target image of the one imaging target or a plurality of target images of the plurality of imaging targets in the image taken by the image pickup means and which indicates a distance between the plurality of target images or a size of the one target image, is sequentially obtained. A display image is enlarged and reduced in accordance with a change in the target image data. Then, the display image processed in such a manner is displayed on a display device.
