Solution Overview
Problem
Existing image sensors face issues with image display delays or failures due to inconsistent terminal specifications and network transmission speeds, leading to inappropriate image resolution and misalignment of processing results, especially when high-resolution images are transmitted without adaptation.
Innovation Solution
An image processor that dynamically adjusts the resolution and transmission rate of images based on terminal capabilities and network load, ensuring appropriate image quality and alignment of processing results by using an information transmission controller to change the resolution and coordinates of superimposed information according to terminal and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution images are transmitted to operation terminals, then image quality is improved, but image display delays and failures occur due to network load and terminal capability variations
Solution Approach 1:
The patent applies dynamics by making the image resolution adaptive rather than fixed. The image processing device dynamically adjusts the resolution of transmitted images based on real-time network load status and terminal capability information. When network load is high or terminal capabilities are limited, the device automatically reduces resolution to prevent display delays and failures, while maintaining high resolution when conditions permit, thus resolving the contradiction between image quality and display reliability.
Solution Approach 2:
The patent changes the resolution parameter of transmitted images based on network load and terminal capabilities. By monitoring network status and terminal specifications, the system adjusts the resolution parameter dynamically - reducing it when necessary to ensure reliable display, and maintaining it high when conditions allow, thereby resolving the contradiction between maintaining high image quality and ensuring reliable display across varying conditions.
2Productivity
If resolution conversion (downsampling) is applied to captured images before transmission, then frame update rate is guaranteed, but image quality deteriorates and useful information is lost
Solution Approach 1:
The system dynamically determines whether to apply resolution conversion based on terminal capability information and network conditions. Instead of always downsampling, the device adapts its processing - applying resolution conversion only when necessary (e.g., when terminal screen resolution is low or network bandwidth is limited), and transmitting full-resolution images when terminals have high capabilities, thus maintaining both high frame update rates and image quality as appropriate.
Solution Approach 2:
The patent changes the resolution parameter selectively based on terminal capabilities and network status. By adjusting the resolution conversion level dynamically - using higher resolution when terminals support it and lower resolution when they don't - the system optimizes the balance between frame update rate and image quality, avoiding unnecessary information loss while ensuring smooth display performance.
3Stability of the object's composition
If graphics indicating processing results are superimposed on images before resolution conversion, then alignment is maintained, but graphics become blurred and visibility is reduced
Solution Approach 1:
The patent applies preliminary action by performing resolution conversion on the base image before superimposing graphics, rather than the reverse order. By first downsampling the image to the appropriate resolution for the terminal, then calculating and applying corresponding adjusted coordinates for the graphics, the system ensures that graphics remain sharp and visible while maintaining proper alignment with the resolved image, thus resolving the contradiction between alignment and visibility.
Solution Approach 2:
The system changes the coordinate parameters of graphics based on the resolution conversion applied to the image. By calculating transformed coordinates that account for the resolution reduction, the graphics are positioned correctly on the lower-resolution image without being blurred, maintaining both alignment accuracy and visual clarity.
4Device complexity
If constant resolution images are transmitted without considering terminal specifications, then transmission simplicity is maintained, but display performance varies across different terminals
Solution Approach 1:
The patent achieves universality by making the image processing device adaptable to multiple terminal types with different capabilities. By collecting terminal information (screen resolution, processing power, network conditions) and adjusting image resolution accordingly, the system provides optimal display performance across diverse terminals - from low-end mobile devices to high-end workstations - without requiring dedicated applications for each terminal type, thus resolving the contradiction between transmission simplicity and terminal compatibility.

AI summary
An image processor includes an information transmission controller that transmits data including an image of an object and information indicating a result of a process to a terminal through a network. The information transmission controller changes a resolution of a transmission image to be transmitted to the terminal in accordance with at least one of a capability of the terminal, a load status of the terminal, a load status of the network, or a load status of the image processor, and adjusts coordinates on the transmission image at which the information is to be superimposed in accordance with the changed resolution.
