Camera Focus Mode Switching via Controller Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing technologies do not allow users to seamlessly switch between autofocus (AF) and manual focus (MF) modes during the image capturing standby period or after the image capturing preparation instruction, requiring additional operations to return to AF mode or maintain MF mode temporarily.
Innovation Solution
An image capturing control apparatus that allows switching between AF and MF modes based on user operations using a controller ring, enabling manual focus adjustment during the image capturing standby period or after the preparation instruction, and automatically returning to AF mode when the preparation instruction is cancelled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the AF mode is switched to MF mode by ring rotation operation before image capturing preparation instruction, then the user can perform manual focus adjustment during standby period, but the mode cannot be switched back to AF mode automatically when preparation instruction is released
Solution Approach 1:
The system monitors the state of the image capturing preparation instruction and automatically switches the focusing mode back to AF when the preparation instruction is released. This feedback mechanism eliminates the need for manual mode switching operations, resolving the contradiction by making the system responsive to user intent through automatic state detection and mode transition.
2Adaptability or versatility
If the AF start switch is turned on to switch to AF mode, then AF adjustment can be executed, but the user needs to operate the switch again to return to AF mode after temporary MF usage
Solution Approach 1:
The system automatically manages the focusing mode transitions based on the state of the image capturing preparation instruction. When the preparation instruction is released, the system self-corrects by switching back to AF mode without requiring user intervention. This self-service approach reduces operational complexity while maintaining full adaptability in focusing mode usage.
3Measurement precision
If the focusing mode is switched to MF mode during image capturing standby period, then precise focus adjustment can be performed, but the mode reverts automatically when preparation instruction is released
Solution Approach 1:
The focusing mode is made dynamic rather than static, automatically adapting its state based on the image capturing preparation instruction status. The system allows MF mode during preparation for precise focus adjustment, then automatically reverts to AF mode when preparation is released, creating a flexible temporal pattern that matches user workflow needs.

AI summary
An image capturing control apparatus configured to switch between a first mode in which a specific setting relating to image capturing is automatically performed and a second mode in which the specific setting is performed based on an amount of user operation and a control unit configured to perform control, in a case where the first mode is switched to the second mode by a user operation before the image capturing preparation instruction is received, the second mode is not switched to the first mode based on a release of the image capturing preparation instruction, and in a case where the first mode is switched to the second mode by a user operation during the image capturing preparation instruction is being received, the second mode is switched to the first mode based on the release of the image capturing preparation instruction is being received.
