Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In camera systems with multiple individual-eye lenses, adjusting focus and other settings can cause changes in the region of the individual-eye image, making it difficult to perform appropriate processing.
Innovation Solution
An interchangeable lens system with a movable unit that allows individual-eye lenses and light sources to move integrally along the optical axis, ensuring that emission positions do not overlap, facilitating appropriate processing by maintaining consistent image regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If focus and other settings are adjusted by feeding out individual-eye lenses in the optical axis direction, then focus adjustment capability is improved, but the region of the individual-eye image on the captured image changes, making it difficult to perform appropriate processing
Solution Approach 1:
The patent makes the light sources movable along the optical axis integrally with the individual-eye lenses. When the lenses are fed out for focus adjustment, the light sources move simultaneously, maintaining their relative positions and ensuring that the irradiation light regions remain consistent with the individual-eye image regions throughout the adjustment process
Solution Approach 2:
The patent integrates the light sources with the movable unit that contains the individual-eye lenses. Both components are configured to move together as a single assembly, ensuring coordinated movement and maintaining the spatial relationship between the imaging lights and irradiation lights during focus adjustment
2Adaptability or versatility
If multiple individual-eye lenses are arranged in the optical axis direction to capture multi-viewpoint images, then multi-viewpoint imaging capability is improved, but the emission positions of imaging lights may overlap, causing processing difficulties
Solution Approach 1:
The patent arranges the light sources at specific positions that do not overlap with the emission positions of the imaging lights from the individual-eye lenses. Each light source is positioned in a dedicated region, ensuring that the irradiation light for autofocus does not interfere with the imaging light paths of the multi-eye lenses

Function Achieved in This Case
Enables accurate processing and adjustment of focus and other settings without disrupting the individual-eye image regions, improving the overall performance and convenience of the camera system.
Implementation Method 1
one or a plurality of light sources configured to be movable along the optical axis integrally with the movable unit and the plurality of individual-eye lenses, and arranged such that an emission position of an irradiation light emitted to an image sensor provided in a camera body does not overlap with the emission position of the imaging light of each of the plurality of individual-eye lenses

AI summary
The present technology relates to an interchangeable lens, an information processing apparatus, an information processing method, and a program for enabling appropriate processing. A multi-eye interchangeable lens includes a lens barrel, a movable unit, a plurality of individual-eye lenses, and a light source. The movable unit is configured to be movable along an optical axis with respect to the lens barrel. The plurality of individual-eye lenses is configured to be integrally movable with the movable unit and is arranged such that emission positions of imaging lights emitted via the individual-eye lenses do not overlap with one another. One or a plurality of the light sources is configured to be movable along the optical axis integrally with the movable unit and the plurality of individual-eye lenses, and is arranged such that an emission position of an irradiation light emitted to an image sensor provided in a camera body does not overlap with the emission position of the imaging light of each of the plurality of individual-eye lenses. The present technology can be applied to, for example, an interchangeable lens from which a plurality of individual-eye lenses is fed out, a camera system, or the like.
