Interchangeable Lens Accessory Aperture Control Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens interchangeable type camera systems lack an accessory with an aperture unit to adjust light amounts, limiting the functionality for storage and playback of focus positions.
Innovation Solution
An accessory is introduced that is detachably attached between an interchangeable lens and an image pickup apparatus, featuring an aperture unit, a communication unit, a memory for storing aperture diameter information, and a processor to control the aperture unit based on user instructions for storage and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an aperture unit is added to the accessory to adjust light amounts, then the functionality for moving and still image capturing is improved, but the device complexity increases
Solution Approach 1:
The accessory integrates an aperture unit that can be used for both moving image capturing and still image capturing, allowing a single device to perform multiple functions. The aperture unit adjusts light amounts for different imaging modes, eliminating the need for separate accessories for different capturing types.
2Ease of operation
If multiple storage modes and playback modes are implemented for aperture diameter information, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The accessory provides dynamic storage and playback modes for aperture diameter information. The first storage mode stores information at the timing when the second instruction information is acquired, while the second storage mode stores at a different timing. Similarly, the first playback mode controls the aperture unit at the timing when the third instruction information is acquired, while the second playback mode controls at a different timing. This dynamic approach allows flexible operation for different user needs.
3Ease of operation
If the accessory stores and plays back aperture diameter information with timing flexibility, then the ease of operation is improved, but the loss of time is reduced
Solution Approach 1:
The accessory allows the aperture diameter information to be stored in advance at different timings (first storage mode stores at the timing when the second instruction information is acquired, second storage mode stores at a different timing). This preliminary storage enables quick playback when needed, reducing the time loss during actual operation.

AI summary
An accessory detachably attached between an interchangeable lens and an image pickup apparatus includes a processor configured to acquire first, second, and third instruction information. In response to the second instruction information, the processor has at least one of a first storage mode for storing diameter information in a memory at a first timing when the second instruction information is acquired, and a second storage mode for storing the diameter information in the memory at a second timing different from the first timing. In response to the third instruction information, the processor has at least one of a first playback mode in which the aperture unit is controlled using the diameter information at a third timing when the third instruction information is acquired, and a second playback mode in which the aperture unit is controlled using the diameter information at a fourth timing different from the third timing.
