Image Recognition Shutter Control via Gesture Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling an image pickup device, such as cable-based and wireless remote controls, are limited by power supply issues and restricted range, requiring additional devices and leading to inflexible operation.
Innovation Solution
An image recognition system is employed to control the electronic shutter using a database of recognizable characteristic images, allowing users to define custom gestures for remote operation without the need for external control devices, enabling flexible and power-independent control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless remote control device is used, then remote operation capability is improved, but power supply limitation and device complexity increase
Solution Approach 1:
The image pickup device itself performs the control function by recognizing gestures or images through its own camera and processing unit, eliminating the need for separate remote control devices and their power supplies. The device serves itself by using its computational resources to interpret user gestures and trigger shutter operations accordingly.
2Reliability
If cable based control is used, then control reliability is improved, but operational range is limited by cable length
Solution Approach 1:
The mechanical cable-based control system is replaced with an optical recognition system. The device uses its camera to capture images and a processing unit to recognize gestures, replacing the physical connection with wireless optical communication and computational recognition, thereby extending operational range without compromising control reliability.
3Ease of operation
If additional remote control device is used, then shutter control functionality is improved, but device portability and simplicity deteriorate
Solution Approach 1:
The image pickup device is designed to perform multiple functions: it uses its camera not only for capturing photographs but also for recognizing user gestures to control the shutter. The processing unit handles both image processing for photography and gesture recognition for control, consolidating multiple functions into a single device and eliminating the need for separate remote controls.
4Ease of operation
If power supply device in remote control is used, then remote control operation is enabled, but operational reliability deteriorates when power is insufficient
Solution Approach 1:
The power supply requirement for remote control is extracted and eliminated by using the image pickup device's own power supply to run its camera and processing unit for gesture recognition. The gesture recognition function is integrated into the main device, removing the separate power supply component that causes reliability issues when battery power is low.

AI summary
An image pickup device uses an image recognition system to control the actuation of an electronic shutter. The image pickup device has an optical lens that picks up an image through the electronic shutter and the image so picked up is detected by an image detection device and converted into image data that are applied to a temporary image holding memory of a micro-controller. The micro-controller carries out comparison of the image of a selected target that is picked up the optical lens with respect to a recognizable characteristic image contained in a recognizable characteristic image database. If the image of the selected target so picked up is recognized to match the recognizable characteristic image, then the micro-controller sends out a shutter control signal to control the actuation of the electronic shutter via a shutter control circuit to photograph and store the image of the target in an image storage memory.
