Display Unit Segmentation for Auxiliary Illumination in Dark Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing devices struggle to facilitate image checking in dark environments, as the display unit acts as auxiliary light during photography but displays dark images before photographing, making it difficult for users to adjust settings effectively.
Innovation Solution
Incorporating an illumination sensor to detect ambient light levels, allowing the display unit to function as auxiliary light only when necessary, with separate regions for image display and illumination, ensuring brighter image information is visible for composition adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display unit is used as auxiliary light during photographing in dark environments, then the imaging quality is improved, but the image checking capability before photographing deteriorates
Solution Approach 1:
The display unit is divided into two functional regions: a first region that displays the captured image for composition checking, and a second region that emits light as auxiliary illumination. This segmentation allows the display to simultaneously provide both image display and lighting functions, resolving the contradiction between imaging quality and image checking capability.
Solution Approach 2:
Different regions of the display unit are assigned different luminance characteristics. The second region emits higher luminance to provide auxiliary light for the subject, while the first region maintains sufficient luminance to allow users to check the captured image composition. This local differentiation of quality enables both functions to coexist effectively.
2Illumination intensity
If the display unit emits high luminance to function as auxiliary light, then the illumination capability is improved, but the power consumption increases
Solution Approach 1:
The display unit is segmented into regions with different luminance requirements. Only the second region emits high luminance for auxiliary lighting, while the first region consumes less power for image display. This partial activation reduces overall power consumption compared to illuminating the entire display at high brightness.
Solution Approach 2:
The luminance parameter of the display unit is dynamically adjusted based on spatial location and operational mode. The second region operates at high luminance when needed for lighting, while the first region operates at lower luminance for viewing, optimizing the balance between illumination intensity and power consumption.

AI summary
In an information processing device configured to include an imaging unit, a display unit, and an illumination sensor, to capture image information by the imaging unit, and to perform processing on the captured image information, the display unit and the imaging unit are disposed on the same surface, the capture processing is performed in a normal mode when a detected value of the illumination sensor is a predetermined value or more, and the capture processing is performed in a dark-place mode when the detected value of the illumination sensor is a predetermined value or less.
