Secondary Camera Gesture Shutter Release to Reduce Camera Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for mitigating camera shake in photography, such as delaying image capture or using additional hardware, are either inconvenient, costly, or require intensive processing and power resources, and often degrade image quality.
Innovation Solution
A system that uses a motion sense image sensor to detect user gestures for initiating image capture, allowing the primary image sensor to capture images without physical contact, thereby reducing camera shake without the need for additional hardware or intensive processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical button or virtual button is pressed to initiate image capture, then the image capture function is activated, but the camera may move causing hand shaking or camera shake that degrades image quality
Solution Approach 1:
The patent introduces a second camera as an intermediary device to detect the user's hand gesture for image capture initiation. Instead of directly pressing a button that causes camera movement, the system uses the second camera to monitor the user's hand in the field of view and automatically triggers capture when a predefined gesture is detected, eliminating the need for physical contact with the camera device.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with an optical detection system. The second camera captures video frames of the user's hand, and image processing algorithms analyze these frames to detect gestures, substituting the mechanical interaction (pressing buttons) with an optical-field-based interaction that does not cause camera movement.
2Manufacturing precision
If image capture is delayed to mitigate camera shake, then image quality may be improved, but the user may miss photographing the desired scene or subject
Solution Approach 1:
The system performs preliminary action by continuously monitoring the user's hand gesture through the second camera before the actual image capture. The gesture detection and recognition processes occur in advance, allowing the system to trigger capture at the precise moment the user intends, eliminating the need for delayed capture while maintaining image quality.
3Manufacturing precision
If a remote control device is used to send wireless shutter signal, then camera shake is reduced, but additional hardware expense and device complexity increase
Solution Approach 1:
The patent applies multi-functionality by using the second camera, which could be used for various purposes (such as front-facing camera for video calls or selfies), to also serve as the gesture detection mechanism for image capture initiation. This eliminates the need for separate remote control hardware, as the existing second camera is repurposed to control the first camera's capture function.
Solution Approach 2:
The system merges the gesture detection function with the existing second camera hardware. Instead of adding a separate remote control device, the patent combines the control function with the already-present second camera, reducing overall device complexity and hardware requirements while achieving shake-free capture initiation.
4Manufacturing precision
If anti-shake algorithm is used to compensate for motion, then image quality may be maintained, but processing resources and electrical power consumption increase
Solution Approach 1:
The patent extracts the source of camera shake (manual button pressing) by using gesture recognition through the second camera. Instead of applying post-processing anti-shake algorithms that consume processing resources and power, the system prevents shake at the source by enabling contactless capture initiation, thereby eliminating the need for energy-intensive correction algorithms.

AI summary
Capturing a target image includes activating a first image sensor for capturing the target image. A sequence of images is captured with a second image sensor while the first image sensor remains activated. A determination is made as to whether the sequence of images captured by the second image sensor includes a shutter gesture while the first image sensor remains activated. If a shutter gesture is included in the sequence of images captured by the second image sensor, the first image sensor captures the target image in response.
