Imaging Apparatus Subject Tracking via Dynamic Remarkable Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face usability issues when tracking a moving subject, as the zooming frame often goes out of frame unexpectedly, and users cannot change the tracking target without stopping the recording mode.
Innovation Solution
The imaging apparatus includes moving picture capturing means, first and second display controlling means to update and reset the display position of a remarkable point to track the subject when the shutter button is pressed halfway and released, allowing the user to easily adjust and maintain focus on the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the zooming frame is controlled to track the moving target subject, then the subject can be dynamically followed, but the subject may go out of frame unexpectedly when the frame is located on the edge
Solution Approach 1:
The patent applies dynamics by making the remarkable point's display position changeable rather than fixed. The remarkable point dynamically adjusts its position based on the subject's location within the frame, allowing it to move to optimal positions for tracking while avoiding edge cases where the subject might go out of frame. This dynamic adjustment resolves the contradiction between automatic tracking and reliable subject retention.
2Extent of automation
If the tracking has started, then the zooming frame can follow the moving subject, but the user cannot change the tracking target without stopping recording mode
Solution Approach 1:
The patent segments the shutter button operation into distinct halfway press and full press states. The halfway press activates tracking mode, while the full press captures an image. This segmentation allows the user to switch between tracking and image capture modes without stopping recording, resolving the contradiction between maintaining tracking functionality and enabling easy target switching.
Solution Approach 2:
The remarkable point acts as an intermediary element between the user and the tracking system. By displaying the remarkable point at a predetermined position that can be manually adjusted, the user can easily switch tracking targets by simply changing the remarkable point's position, without needing to stop recording mode. This intermediary mechanism enables seamless target switching while maintaining the tracking function.
3Stability of the object's composition
If the remarkable point is displayed at a predetermined position, then the display is simple and stable, but the user cannot easily adjust focus on the subject when the subject goes out of frame
Solution Approach 1:
The patent applies dynamics by making the remarkable point's display position changeable rather than fixed. The remarkable point dynamically adjusts its position based on the subject's location within the frame, allowing it to move to optimal positions for tracking while avoiding edge cases where the subject might go out of frame. This dynamic adjustment resolves the contradiction between automatic tracking and reliable subject retention.

AI summary
Once an imaging mode is set, an imaging apparatus displays a through image with a tracking frame on the predetermined position. If a shutter button is pressed halfway, an object that is overlapped by the tracking frame is recognized as a main subject that a user wants to capture. Until the shutter button is fully pressed or until the halfway-press is released, it is detected where the recognized subject is in frame image data that is captured in sequence, and the tracking frame is displayed based on the detected position. If the halfway press of the shutter button is released before the shutter button is fully pressed, the tracking frame is displayed on the predetermined position. Then if the shutter button is pressed halfway once again, the process is repeated.
