Main Object Reselection Control for Accurate Autofocus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems fail to prevent users from reselecting objects that they are less likely to determine as major objects, especially when multiple objects of the same type are detected, leading to incorrect autofocus targets.
Innovation Solution
An image processing apparatus that includes a detection unit to identify objects and a main object selection unit that determines whether to allow reselection based on object overlap and type combination, preventing the selection of less relevant objects as the main object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows free reselection of main objects from detected objects, then the user has flexibility to choose any object, but the user may reselect objects that are less likely to be the intended major object
Solution Approach 1:
The system changes the parameter of object selection eligibility by evaluating spatial relationships (overlap conditions) and object type combinations. Objects are dynamically classified as selectable or non-selectable based on these parameters, preventing users from reselecting objects that are unlikely to be the intended major object while maintaining flexibility for appropriate selections.
Solution Approach 2:
The system introduces an intermediary evaluation mechanism that mediates between the user's reselection request and the actual main object selection. This intermediary process checks spatial overlap conditions and object type compatibility before permitting reselection, ensuring that only appropriate objects can be selected as new main objects.
2Adaptability or versatility
If the system detects multiple objects of the same type, then the system can identify multiple potential main objects, but the user cannot switch between them
Solution Approach 1:
The system changes the selection status parameter from fixed to dynamic by evaluating spatial relationships. When multiple objects of the same type are detected, the system determines which objects are eligible for reselection based on whether they overlap with other detected objects. Non-overlapping objects are marked as selectable, enabling users to switch between multiple objects of the same type.
3Device complexity
If the system permits reselection based solely on object type, then the selection process is simple, but it cannot prevent selection of inappropriate objects
Solution Approach 1:
The system adds spatial relationship parameters (overlap conditions) to the selection criteria while maintaining object type evaluation. This multi-parameter approach determines object selectability: objects that do not overlap with other detected objects and have compatible type combinations are permitted for reselection, while overlapping objects are restricted. This enhances selection accuracy without significantly increasing system complexity.

AI summary
In a case where a user selects a plurality of types of detected objects while switching a main object using an operation member for indicating a direction, the user may select an object that the user is less likely to determine as a major object. An image processing apparatus determines whether to permit any of a plurality of objects to be reselected as a new main object according to whether a region of any of the plurality of objects overlaps a region of another object and a combination of a type of any of the plurality of objects and a type of the main object.
