Camera Region-Selective Image Transmission to Reduce Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems waste communication bandwidth by transmitting unnecessary image data when outputting images from different regions of a single camera, leading to inefficiencies in data transmission.
Innovation Solution
A system where a camera generates and transmits image data for specific regions within its imaging area in response to alternating requests from a connected device, using identification information to distinguish and position the images, thereby reducing unnecessary data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the camera transmits only necessary image data for specific regions, then bandwidth efficiency is improved, but the system complexity increases due to region-based data selection and identification
Solution Approach 1:
The imaging region is divided into multiple selectable regions (first region, second region, etc.), allowing the camera to transmit only the image data corresponding to the requested region rather than the entire imaging region. This segmentation enables bandwidth efficiency by reducing unnecessary data transmission while the identification information mechanism manages the complexity of region-based selection.
Solution Approach 2:
Identification information is introduced as an intermediary element that accompanies the image data during transmission. This identification information enables the device to distinguish between image data from different regions and correctly arrange them in the synthesized image, managing the system complexity through a standardized tagging mechanism rather than complex region-coordinate systems.
2Productivity
If the camera transmits image data for multiple regions simultaneously, then productivity is improved, but the amount of transmitted data increases
Solution Approach 1:
The device requests image data from different regions in an alternating periodic manner (first request for first region, second request for second region, and so on). This periodic action enables the simultaneous output of multiple region images to be achieved through time-division multiplexing, maintaining productivity while minimizing the amount of transmitted data at any given moment, as only one region's image data is transmitted per request cycle.
3Reliability
If identification information is added to distinguish image data from different regions, then reliability is improved, but the data transmission overhead increases
Solution Approach 1:
Identification information is added locally to each image data packet rather than using a global complex addressing system. Each image data transmission includes identification information specific to its region (first identification information for first region, second identification information for second region), enabling reliable distinction with minimal overhead. This local quality approach ensures reliability by making the region identity self-contained within each data packet.

AI summary
A system includes a device and a camera connected to the device through a wired or wireless connection. The device alternately transmits to the camera, a first request that causes the camera to transmit image data corresponding to a first region in an imaging region of the camera and a second request that causes the camera to transmit image data corresponding to a second region in the imaging region. The camera generates first image data corresponding to the first region from entire image data and transmits first data including the first image data to the device in accordance with the first request, and generates second image data corresponding to the second region from the entire image data and transmits second data including the second image data to the device in accordance with the second request. The device outputs a synthesized image including a first image based on the first image data and a second image based on the second image data.
