Illuminated Target Display with Automatic Virtual Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques require users to manually adjust light source devices to achieve desired illuminating conditions, which can be burdensome.
Innovation Solution
An information processing apparatus that allows users to set desired illuminating conditions through simple operations by adjusting the ratio of environmental and virtual light sources based on the percentage of the target object in the displayed image, using a receiving circuit and display control circuit to generate and display images accordingly.

Engineering Contradiction Analysis
1Illumination intensity
If users manually adjust light source devices to achieve desired illuminating conditions, then the illuminating condition can be precisely controlled, but the operation becomes burdensome and complex
Solution Approach 1:
The system automatically adjusts the virtual light source position and orientation based on the displayed area of the target object, eliminating the need for manual user adjustment. The illuminating condition is set autonomously according to the display control circuit's detection of whether a first area or second area is being displayed.
Solution Approach 2:
The system changes the parameters of the virtual light source (position and orientation) based on the display area parameter. When switching between displaying a first area or second area of the target object, the light source parameters are automatically adjusted to provide appropriate illumination without requiring manual intervention.
2Illumination intensity
If users manually move the light source device, then the desired illuminating condition can be achieved, but the operation complexity and time consumption increase
Solution Approach 1:
The system pre-establishes the relationship between display area and light source position. The virtual light source is automatically positioned and oriented based on the current display state, so the illuminating condition is ready in advance according to the displayed area, eliminating adjustment time.
Solution Approach 2:
The display control circuit automatically controls the virtual light source parameters based on the displayed area of the target object. The system serves itself by autonomously adjusting illumination without requiring user time and effort for manual light source positioning.

AI summary
An information processing apparatus receives an instruction to display a first area of a target object on a screen or an instruction to display a second area, of the target object, smaller than the first area on the screen and displays an image of the target object illuminated with light under an illuminating condition according to an instruction that the receiving circuit receives on the screen.
