Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for adjusting illumination light components in multi-device imaging setups require time-consuming and labor-intensive manual adjustments, making it difficult to achieve precise control over irradiation areas, especially in studios with multiple types of illuminating devices.
Innovation Solution
An imaging support device with an imaging element, illumination control unit, image acquisition unit, individual irradiation area detection unit, irradiation area image generation unit, and operation input receiving unit that captures images of the object under different illumination components, detects irradiation areas, generates an irradiation area image with division marks, and allows for light adjustments through a touch panel or gesture detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of illumination light components is performed, then the amounts of illumination light can be controlled, but the adjustment process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent creates a virtual copy of the imaging range by projecting illumination area lights that represent the irradiation areas of individual illuminating devices. This virtual model allows operators to visualize and adjust irradiation areas without physically moving or adjusting each illuminating device, significantly reducing adjustment time while maintaining precision.
Solution Approach 2:
The patent introduces an intermediary system consisting of the illumination area lights and control unit that mediates between the operator and the actual illuminating devices. Instead of directly adjusting physical illuminating devices, operators interact with the virtual illumination area representation, which then translates adjustments to the actual devices, simplifying the control process.
2Illumination intensity
If multiple illuminating devices are used to provide comprehensive illumination, then the imaging quality improves, but the complexity of checking and adjusting each irradiation area increases
Solution Approach 1:
The patent segments the overall illumination system into individual controllable units by displaying separate illumination area lights for each illuminating device. This segmentation allows operators to manage and adjust each device's irradiation area independently through the visual representation, making the complex multi-device system more manageable.
Solution Approach 2:
The patent adds a visual dimension to the control interface by projecting illumination area lights that spatially represent the irradiation areas. This dimensional visualization transforms the abstract concept of irradiation coverage into tangible visual elements that operators can easily interpret and manipulate, reducing the perceived complexity.
3Ease of manufacture
If virtual brightness adjustment is performed after imaging, then the captured images can be modified, but the delicate expression of shading and texture is lost compared to actual light adjustment
Solution Approach 1:
The patent enables preliminary adjustment of illumination parameters before actual imaging occurs. By allowing operators to visualize and adjust irradiation areas using the illumination area lights prior to capture, the system ensures optimal lighting conditions are established in advance, preserving the delicate expression of shading and texture in the original capture rather than relying on post-processing.

AI summary
An illumination control unit selectively turns on strobe devices and a strobe light emitting unit. An image acquisition unit captures an image of an object through an imaging element and acquires individual illumination images. An individual irradiation area detection unit detects individual irradiation areas which are areas irradiated with each illumination light component in the imaging range of the imaging element on the basis of the individual illumination images. An irradiation area image generation unit generates an irradiation area image obtained by inserting division marks indicating each individual irradiation area into the image of the object. An irradiation area image output unit displays the irradiation area image on a rear display unit. The user observes the irradiation area image and can simply recognize each individual irradiation area.
