Quick View Image Generation for Reduced Camera Capture Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cameras require a significant amount of time to prepare for the next shot after capturing an image, as they need to complete processing and storage tasks before being ready for the next photograph.
Innovation Solution
The electronic apparatus includes a photographing unit, a processing unit, and a display unit that allows for the creation and display of quick view images immediately after capturing an image, enabling a second image to be captured quickly if a shutter release signal is inputted within a reference time, thereby reducing the time needed to prepare for the next shot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic apparatus completes all processing and storage tasks before capturing the next image, then the reliability of image processing is improved, but the time required to prepare for the next shot increases
Solution Approach 1:
The patent applies preliminary action by creating and displaying a quick view image immediately after image capture, before completing all processing and storage tasks. The processing unit generates a thumbnail or preview version of the captured image and displays it on the display unit, allowing the user to see the captured content instantly. This preliminary display action occurs while the full image is still being processed and stored, thus reducing the waiting time for the next shot without compromising the final image quality or processing reliability.
2Speed
If the electronic apparatus displays a quick view image immediately after capturing an image, then the speed of image capture is improved, but the complexity of the processing unit increases
Solution Approach 1:
The patent applies segmentation by dividing the image processing into multiple stages and versions. The processing unit creates different representations of the same image: a full-resolution image for quality and a downsampled quick view image for immediate display. This segmentation allows the system to display an image instantly while the full processing continues in the background, achieving fast capture speed without requiring a completely redesigned complex processing architecture.
3Manufacturing precision
If the electronic apparatus processes and stores the full image before displaying it, then the manufacturing precision of the image quality is improved, but the loss of time before next capture increases
Solution Approach 1:
The patent applies copying by creating a simplified copy or representation of the captured image for immediate display. Instead of waiting for the full high-quality image processing to complete, the system generates a lower-resolution quick view copy that can be displayed instantly. This copying approach allows the user to see the captured content without delay while the original high-quality image continues to be processed and stored in the background, thus maintaining image quality precision without increasing capture time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the time between capturing consecutive images by allowing for immediate display and processing of quick view images, enabling faster image capture and reducing the overall preparation time for subsequent photographs.
Implementation Method 1
The photographing unit converts incident light into electricity to create an image signal

AI summary
An electronic apparatus includes a photographing unit, a processing unit, and a display unit. The photographing unit creates an image signal and captures a first image corresponding to a first shutter release signal. The processing unit creates a first quick view image of the first captured image and creates a live view image based on the image signal. The display unit displays the first quick view image and the live view image. If a second shutter release signal is inputted within a first reference time from a moment at which the first shutter release signal is inputted, the processing unit creates and displays, at the display unit, a second quick view image corresponding to the second shutter release signal. If the second shutter release signal is not inputted within the first reference time, the processing unit creates and displays, at the display unit, the live view image.
