Image Processing Device Object Detection Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices face challenges in accurately detecting objects due to differences in exposure between live view and still images, leading to erroneous detection and increased processing times, especially with high-speed imaging and AI integration, which can affect the quality of both live view and still picture processing.
Innovation Solution
An image processing device that selectively acquires images for live view and still images, with an object detecting unit that detects object information from live view images immediately before or after acquiring a still image, allowing for synchronized processing and exposure control to minimize object deviation and ensure accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If object detection is performed from both live view images and still images, then object tracking accuracy is improved, but processing time increases and may exceed predetermined periods
Solution Approach 1:
The patent performs object detection from live view images before capturing still images, using the detected object information to guide still image processing. This preliminary detection allows the system to prepare object masks and detection results in advance, reducing the processing time required during still image development while maintaining accurate object tracking.
2Productivity
If high-speed processing using dedicated hardware is implemented, then processing speed is improved, but cost and power consumption increase
Solution Approach 1:
The patent implements periodic object detection at live view frame rates, performing detection operations at regular intervals rather than continuously processing every frame. This periodic approach maintains adequate object tracking performance while reducing overall processing load, allowing standard processors to handle the workload without requiring dedicated high-speed hardware.
3Measurement precision
If object detection processing time is increased to improve detection accuracy, then detection quality is improved, but live view tracking becomes unsuccessful
Solution Approach 1:
The patent performs object detection from live view images before still image capture, using the detected object information to guide subsequent still image processing. This preliminary detection allows the system to prepare object masks and detection results in advance, reducing the processing time required during still image development while maintaining accurate object tracking.

AI summary
In order to obtain an image processing device capable of performing imaging processing appropriately using object information, the image processing device includes an imaging unit which is capable of selectively acquiring an image for live view and a still image, a drive control unit which acquires the still image through a predetermined operation when the image for live view is periodically acquired at a predetermined first period, and acquires an image for live view again immediately after the still image is acquired, an object detecting unit which detects object information from an image for live view immediately before or immediately after the still image is acquired, and a signal processing unit which processes the still image on the basis of the object information detected by the object detecting unit.
