Tracking Object Selection Apparatus for Accurate Autofocus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses face difficulties in selecting a tracking object when multiple objects are moving or have low visibility, leading to unintended object selection and inaccurate autofocus and exposure control.
Innovation Solution
A tracking object selection apparatus that displays candidate tracking objects at a predetermined position, extracts features, determines the orientation of the object, and stores the image of the candidate tracking object region when in a predetermined state, allowing users to easily select the intended object through a simple operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user selects a tracking object by touching the object in the displayed image, then the selection operation is simple, but the selected object may be unintended when the object moves between the display update and selection moment
Solution Approach 1:
The system pre-calculates and stores the positional relationship between the imaging device and candidate tracking objects before the user makes a selection. This preliminary action captures the spatial context at the moment of selection, ensuring that even if objects move during display updates, the selection is made based on the correct positional data from the selection moment rather than from an earlier display state.
2Stability of the object's composition
If the imaging apparatus tracks only static objects, then the tracking is stable, but the apparatus cannot track moving objects which are common in video shooting
Solution Approach 1:
The system dynamically updates the positional relationships between the imaging device and tracking objects as objects move. Instead of assuming static positions, the apparatus continuously recalculates spatial relationships based on current object positions, allowing accurate selection and tracking of moving objects while maintaining selection reliability through real-time positional awareness.
3Stability of the object's composition
If the camera remains stationary during object selection, then the image position is stable, but the user cannot operate the camera buttons which causes camera movement and image position change
Solution Approach 1:
The system captures and stores the positional relationship data at the moment of selection before any subsequent camera movement occurs. This preliminary capture of spatial data ensures that the selection is based on the camera position at the selection moment, not affected by later movements caused by button operations or other user interactions.

AI summary
Provided is a tracking object selection apparatus (1a) which selects a tracking object (103xm). The tracking object selection apparatus (1a) includes a synthesis unit (306) which synthesizes an input image (9Ib) and an image (93) so that the image is disposed at a predetermined position (92P), a display unit (307), and a selection unit (308) which selects, as the tracking object (103xm) in a predetermined process, a detected object (301x) when an operation (104L2) is performed on the image (92) displayed at the predetermined position (92P).
