Zoom Control Mode Switching for Fine Composition Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic zoom functions in imaging apparatuses lack the ability to allow operators to perform fine adjustments in composition without impairing operability, as they do not accommodate temporary fine-tuning of zoom control based on user operations.
Innovation Solution
An apparatus with an acquisition unit for object information, a setting unit for reference size, and a control unit that switches between modes for zoom control, allowing temporary adjustments based on user operations and returning to a predetermined size after a set time, ensuring compatibility with both automatic and manual zoom operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic zoom control maintains object size based on predetermined reference size, then zoom control automation is improved, but operator's ability to perform fine adjustment of composition is impaired
Solution Approach 1:
The system dynamically switches between automatic zoom control mode and manual fine adjustment mode based on operator input. When the operator performs a specific operation (e.g., pressing a button or touching the screen), the system transitions from automatic mode to manual mode, allowing temporary fine adjustment of composition. After a predetermined time elapses without further input, the system automatically returns to automatic zoom control mode. This dynamic switching resolves the contradiction by allowing both automation and manual control at different times.
Solution Approach 2:
The system changes the control parameter state by switching between two distinct modes: automatic zoom control mode where the reference size is fixed, and manual fine adjustment mode where the operator can temporarily modify the composition. The transition between these parameter states is triggered by operator input and automatically reverted after a predetermined time, enabling both automated operation and manual fine-tuning without permanent loss of automation.
2Extent of automation
If zoom control is performed based on composition pattern selected from options, then automatic zoom function is improved, but flexibility for temporary fine tuning is lost
Solution Approach 1:
The system provides dynamic adaptability by allowing the operator to temporarily override the predetermined composition pattern when needed. Upon detecting a specific operator operation, the system switches to a mode where the operator can perform fine adjustment of the composition for a predetermined time period. This temporary override capability maintains the benefits of automatic zoom control while providing flexibility for fine-tuning when required, then automatically returns to the original composition pattern-based control.
3Ease of operation
If the system switches between automatic zoom mode and manual adjustment mode, then both automation and manual control are enabled, but system complexity increases
Solution Approach 1:
The mode switching mechanism serves multiple functions: it detects operator intent to perform fine adjustment, transitions between automatic and manual control modes, tracks the predetermined time period, and automatically returns to automatic mode. By consolidating these multiple functions into a single integrated switching mechanism, the system enables both automatic and manual control without proportionally increasing complexity.
Solution Approach 2:
The system automatically manages the mode switching process without requiring operator intervention to return to automatic mode. After the operator initiates manual fine adjustment, the system autonomously tracks the predetermined time period and automatically switches back to automatic zoom control mode when the time elapses, eliminating the need for additional operator actions and reducing the perceived complexity for the user.

AI summary
An apparatus includes a control unit configured to perform zoom control based on a size of an object indicated by acquired information and a set reference size, and a first detection unit configured to detect a first operation for instructing to change the reference size. In a case where the first operation has been detected during the zoom control in a first mode, the control unit performs the zoom control in a second mode until a first time elapses after the first operation has been detected, and, when the first time has elapsed, the control unit switches the second mode to the first mode. In the first mode, the reference size is set to a predetermined size and, in the second mode, the reference size is changed according to the first operation.
