Handheld Device Imaging Sensor Diagonal Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with image capturing capabilities struggle to capture images from a natural angle when the image display surface is in either landscape or portrait orientation, leading to unnatural image perspectives due to the fixed positioning of the imaging sensor relative to the image display surface.
Innovation Solution
The electronic device features a flat box-shaped housing with a rectangular image display surface and an imaging sensor positioned on a corner extending from a diagonal line, allowing the sensor to be tilted towards a reference point on a perpendicular line intersecting the image display surface at its center, enabling image capture from above regardless of the orientation, and includes a handle for stable handling.

Engineering Contradiction Analysis
1Ease of operation
If the imaging sensor is fixed at a standard position on the housing, then the device structure is simple, but the image capturing angle becomes unnatural when the display surface is in portrait orientation
Solution Approach 1:
The imaging sensor is positioned on a diagonal line extending from the image display surface corner, and its optical axis is tilted toward the center of the display surface. This diagonal positioning and angular tilt create a capturing angle that naturally follows the user's face when holding the device in portrait mode, transforming the conventional orthogonal sensor placement into a diagonal configuration that adapts to the display orientation.
2Ease of operation
If the imaging sensor is positioned to capture from above, then natural image perspective is achieved, but the sensor may obstruct the image display surface
Solution Approach 1:
The imaging sensor is positioned at a corner of the housing, specifically on a line extending from the diagonal of the image display surface. This corner placement localizes the sensor to a specific region that does not interfere with the main display area, while the tilted optical axis directs the capturing angle from above to achieve natural perspective without obstructing the display surface.
3Ease of operation
If the imaging sensor optical axis is perpendicular to the housing surface, then the sensor alignment is simple, but the captured image perspective becomes unnatural when viewing the display
Solution Approach 1:
The optical axis of the imaging sensor is tilted at a specific angle toward the center of the image display surface, rather than being perpendicular to the housing surface. This angular parameter change transforms the optical configuration to capture the user's face from above, producing a natural perspective that matches the user's viewpoint when viewing the display, while the tilt angle is optimized to balance perspective quality with structural simplicity.

AI summary
Included is a flat box shaped housing 1 having, on a main surface 1a thereof, a rectangular image display surface 2. Two images whose vertical directions are different from each other by 90 degrees are displayed on the image display surface 2. An imaging sensor 5 is disposed at a portion surrounding the image display surface 2, at a part away from center lines of the image display surface 2 in the height direction and the width direction. An optical axis of the imaging sensor 5 is tilted toward a reference point located on a perpendicular line that perpendicularly intersects the image display surface 2 at the center of the image display surface 2. With the above described configuration, an image captured from a fine angle is obtained.
