Imaging Apparatus Sensor Shift Composition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses using sighting devices for aligning the imaging optical axis often result in monotonous compositions, as the object is typically centered within the imaging range, limiting composition flexibility and creativity in photography.
Innovation Solution
The imaging apparatus incorporates a touch panel and sensor shift mechanism, allowing the user to designate a specific position for the object within the image, enabling the imaging optical axis to be aligned with that position, and optionally performing trimming to adjust the composition without changing the focal distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the object is centered within the imaging range using a sighting device, then the alignment with the imaging optical axis is achieved, but the composition becomes monotonous and composition flexibility is limited
Solution Approach 1:
The patent applies the Dynamics principle by making the imaging range movable relative to the imaging optical axis through sensor shift or trimming operations. The imaging range can be dynamically repositioned to different locations within the image sensor area, allowing the object to be framed at various positions rather than always centered on the optical axis. This dynamic adjustment resolves the contradiction by maintaining precise alignment capability while enabling diverse composition options.
2Adaptability or versatility
If the imaging range is trimmed to reposition the object, then composition variety is improved, but the object size in the image changes
Solution Approach 1:
The patent applies the Parameter changes principle by adjusting the imaging range parameters (position and size) through trimming operations. When the imaging range is trimmed to reposition the object within the frame, the parameters of the imaging area are modified, which consequently changes the apparent size of the object in the captured image. This parameter adjustment enables composition variety while accepting the trade-off in object size.
3Adaptability or versatility
If the focal distance is changed to adjust composition, then the imaging range changes, but this is more complex than simple trimming
Solution Approach 1:
The patent applies the Taking out principle by extracting the composition adjustment function from the focal distance mechanism and implementing it through independent trimming operations. Instead of relying on focal distance changes to adjust the imaging range, the system separates the composition control (through trimming the imaging area) from the focus control (through focal distance adjustment). This extraction simplifies the overall system by providing a more direct and less complex method for composition adjustment.

AI summary
According to the present invention, an imaging apparatus includes: an imaging unit which acquires image data by an imaging lens forming an image of an object on an imaging surface on which imaging pixels are arrayed; a designated position acquiring unit which acquires a designated position on the image data; a sighting device which allows a user to visually recognize an optical axial direction of the imaging lens; and a controller which, on the image data, adjusts a position of an object on an imaging optical axis of the imaging lens, based on the designated position.
