Gaze-Controlled Imaging on Electronic Devices for Focus and Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with line-of-sight input functionality face issues with improper focusing and brightness control when the user's gaze deviates from the intended object, leading to unintended switching of focusing targets and brightness adjustments.
Innovation Solution
An electronic device equipped with a line-of-sight input unit, acquisition unit, display control unit, first and second operation units, and a control unit that processes multiple operations based on the line-of-sight position to ensure proper focusing and brightness control, even when the user's gaze shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If brightness control by line-of-sight input is added to an electronic device that constantly performs focusing control by line-of-sight input, then the user can control both brightness and focusing using line-of-sight input, but the focusing control may not be performed properly and the focusing target may be switched contrary to the user's intention
Solution Approach 1:
The patent segments the control functions by introducing distinct operation units: a first operation unit for selecting imaging control settings (focusing) and a second operation unit for executing image processing (brightness adjustment). This segmentation ensures that line-of-sight input for brightness control does not interfere with focusing control, as each function has its own dedicated input pathway.
Solution Approach 2:
The patent introduces an intermediary mechanism (the first operation unit) between the line-of-sight input and the imaging control settings. This intermediary ensures that focusing targets are set before brightness control operations, preventing unintended switching of focusing targets during brightness adjustment.
2Ease of operation
If the user looks at an object different from the focusing target to control brightness, then the brightness can be controlled as intended, but the focusing target switches contrary to the user's intention
Solution Approach 1:
The patent applies preliminary action by requiring the user to set the focusing target first (through the first operation unit) before performing brightness control (through the second operation unit). This sequence ensures that the focusing target is established in advance, preventing unintended switching during brightness adjustment operations.
3Adaptability or versatility
If multiple controls are performed by line-of-sight input, then the device becomes more versatile, but the operability may deteriorate due to conflicting operations
Solution Approach 1:
The patent segments control operations into distinct phases with dedicated operation units. The first operation unit handles imaging control settings (focusing target selection), while the second operation unit handles image processing (brightness control). This segmentation prevents conflicting operations by ensuring each control function has its own dedicated input pathway and execution sequence.

AI summary
An electronic device includes: a line-of-sight input unit configured to receive a line-of-sight input by a line of sight of a user who looks at a display; an acquisition unit configured to acquire an image that is captured by predetermined imaging control; a display control unit configured to display the acquired image on the display; a first operation unit configured to receive a first operation input by the user; a second operation unit configured to receive a second operation input by the user; and a control unit configured to, in a state where the image is displayed, perform setting of the predetermined imaging control on a basis of a line-of-sight position when the first operation input is performed, and perform image processing on the displayed image on a basis of the line-of-sight position when the second operation input is performed.
