Image Pickup Apparatus Precapture Object Change Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cameras with 'precapture' functions continue to capture unnecessary images when the main object does not change, leading to excessive power consumption and rapid depletion of the recording unit's capacity.
Innovation Solution
An image pickup apparatus that includes a first image sensor, a processor, and a memory with instructions to perform precapture imaging, which detects changes in the main object and adjusts the imaging parameters to reduce power consumption and storage needs by transitioning to a lower power and image quality state when the object is stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera continues to capture images during precapture imaging even when the main object does not change, then the photographer can easily capture the desired image, but power consumption increases and recording unit capacity is depleted quickly
Solution Approach 1:
The system uses an object change detection unit to automatically detect whether the main object has changed during precapture imaging. Based on this detection, the control unit automatically adjusts whether to continue or stop precapture imaging, eliminating the need for manual intervention and preventing unnecessary power consumption while ensuring the desired image is captured.
Solution Approach 2:
The object change detection unit provides feedback about whether the main object has changed to the control unit. This feedback mechanism allows the system to dynamically adjust precapture imaging operations, stopping imaging when the object remains unchanged (saving power) and resuming when changes are detected (ensuring capture quality).
2Ease of operation
If the camera continues to capture images during precapture imaging even when the main object does not change, then the photographer can easily capture the desired image, but the capacity of the recording unit is depleted quickly
Solution Approach 1:
The system automatically monitors object changes and controls precapture imaging accordingly, preventing accumulation of unnecessary images in the recording unit. This self-regulating mechanism ensures recording capacity is used efficiently for valuable images while maintaining ease of capture for the photographer.
Solution Approach 2:
The system extracts and processes only the necessary information (object change detection) to control precapture imaging, rather than continuously capturing all images. This selective approach removes unnecessary image storage while preserving the ability to capture desired images.
3Ease of operation
If the camera captures many unnecessary images during precapture imaging, then the photographer can easily capture the desired image, but the number of images stored increases unnecessarily
Solution Approach 1:
The object change detection unit provides continuous feedback during precapture imaging, allowing the system to distinguish between meaningful object changes (worth capturing) and static scenes (not worth capturing). This feedback-driven control prevents storage of unnecessary images while maintaining capture readiness.
Solution Approach 2:
Instead of continuously capturing images throughout precapture imaging, the system applies partial action by capturing images only when object changes are detected. This selective capturing approach avoids excessive storage of redundant images while ensuring the desired image is captured when needed.

AI summary
An image pickup apparatus includes a first image sensor configured to perform imaging, and a control unit configured to perform precapture imaging, when acquiring a first imaging instruction, to cause the first image sensor to repeatedly perform imaging, and causes the first image sensor to perform main imaging when acquiring a second imaging instruction during the precapture imaging, and a first detecting unit configured to detect a change in a main object to be focused, and to output information about the change in the main object. The control unit changes control in the precapture imaging using the information about the change in the main object.
