Remote Camera Control via Periodic Image Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote operation of digital cameras via electronic control devices results in significant delays due to communication and processing times, making it inconvenient for users to obtain intended results.
Innovation Solution
An imaging system comprising a digital camera and a smartphone with a communication interface that periodically transmits and receives image data, allowing the smartphone to send instructions and display images as if the zoom or release operations have been applied immediately, by generating and displaying images based on received data without waiting for confirmation from the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is implemented via electronic control device, then user can operate camera remotely, but delay time occurs due to communication and processing time
Solution Approach 1:
The camera performs imaging operations in advance based on predetermined shooting conditions stored in advance. When a remote operation request is received, the camera executes the pre-prepared imaging task immediately using previously set parameters, thereby reducing the delay caused by real-time communication and processing.
Solution Approach 2:
The system introduces a server as an intermediary component that stores predetermined shooting conditions and coordinates between the remote device and camera. The server manages the shooting condition database and facilitates efficient communication, allowing the camera to access pre-configured parameters without real-time back-and-forth communication delays.
2Ease of operation
If conventional remote operation is used, then user can control camera settings, but user cannot comfortably obtain results reflecting intended instructions
Solution Approach 1:
Shooting conditions are predetermined and stored in advance on the server before remote operation requests are made. This preliminary preparation ensures that when the user issues a remote command, the camera immediately executes with the intended parameters, guaranteeing that the imaging result accurately reflects the user's instruction without communication delays causing parameter changes.
3Loss of information
If real-time image transmission is implemented, then user can see captured images immediately, but communication time and processing time increase
Solution Approach 1:
The system transmits display images (which are copies or representations of the captured images) to the terminal device instead of transmitting only the original captured images. This allows the user to view image feedback without requiring extensive processing and transmission of full-resolution data, reducing communication time while maintaining visual feedback quality.

AI summary
An image communication apparatus communicating with an imaging apparatus includes a user interface that receives an instruction for setting a shooting condition in the imaging apparatus, a communication interface that periodically obtains an image captured by the imaging apparatus from the imaging apparatus, and communicates a request to the imaging apparatus in response to the instruction, a display device that displays the obtained captured image, and a controller that executes processes according to the instruction on the captured image obtained from the imaging apparatus, and generates a display image, and that displays the display image on the display device when the request is transmitted to the imaging apparatus.
