Camera Control Apparatus Sensitivity Management for Multi-Operator Fine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup systems face challenges in allowing both main and sub-operators to adjust image capture conditions effectively, with main operators experiencing incongruous changes in operation sensitivity when sub-operators make corrections, leading to difficulties in fine adjustments.
Innovation Solution
A control apparatus that adjusts the operation sensitivity of a movable optical member based on the operation amounts and sensitivities of both main and sub-operators, using a processor to generate target values and manage operation unit information, allowing for independent and precise control of image capture conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sub-operator uses the same operation sensitivity as the main operator, then the sub-operator can make corrections, but the image capture conditions change more than expected making fine corrections difficult
Solution Approach 1:
The patent applies local quality by assigning different operation sensitivities to different operators based on their roles. The sub-operator is assigned a second operation sensitivity that differs from the main operator's first operation sensitivity, allowing the sub-operator to make precise fine corrections without excessive changes in image capture conditions.
Solution Approach 2:
The patent changes the parameter of operation sensitivity to resolve the contradiction. By storing and applying different operation sensitivity values (first operation sensitivity for main operator, second operation sensitivity for sub-operator), the system enables the sub-operator to perform fine corrections with appropriate control over image capture condition changes.
2Ease of operation
If the correction amount is gradually reduced in response to main operator commands, then the sub-operator can make corrections, but the main operator experiences incongruous changes in operation sensitivity
Solution Approach 1:
The patent segments the control system into independent sensitivity settings for different operators. By maintaining separate first and second operation sensitivities, the system allows the sub-operator to make corrections while preserving the main operator's control consistency, eliminating incongruous changes in operation sensitivity.
3Adaptability or versatility
If multiple independently operable optical systems are provided for main and sub-operators, then both can adjust image capture conditions, but the lens configuration becomes complicated
Solution Approach 1:
The patent applies universality by using a single optical system that can be controlled by multiple operators with different operation sensitivities. Instead of providing multiple independently operable optical systems, the system allows the same optical components to be adjusted by both main and sub-operators through differentiated sensitivity parameters, reducing lens configuration complexity.

AI summary
A control apparatus which performs control of a movable optical member of an optical apparatus based on a first operation amount of a first operation device and a second operation amount of a second operation device, comprises: a storage that stores information of a first operation sensitivity of the first operation device and a second operation sensitivity of the second operation device; and a processor configured to generate a target value for the control based on the first operation amount, the second operation amount, and the first operation sensitivity and the second operation sensitivity of which information is stored in the storage.
