Digital Imaging Region of Interest Selection via Predefined Tiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital imaging systems require cumbersome and resource-intensive custom programming to define and process regions of interest within images, which hinders efficient data transmission and processing, particularly in industrial applications where only specific parts of an image are needed.
Innovation Solution
Configuring digital imaging devices with pre-defined regions of interest, allowing for selection and transmission of specific tiles of image data using compact syntax and bandwidth negotiation to optimize data transfer, reducing unnecessary data transmission and improving processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom programming is used to define regions of interest, then flexibility in selecting regions is improved, but device complexity and programming difficulty increase
Solution Approach 1:
The patent applies preliminary action by pre-defining a set of candidate regions of interest within the imaging device before operation. These pre-defined regions are stored in the device and can be selected through simple instructions rather than requiring complex custom programming. This resolves the contradiction by maintaining adaptability through selection flexibility while reducing complexity through the use of pre-configured options.
Solution Approach 2:
The patent uses copying by providing a simplified instruction set that references pre-defined regions rather than requiring users to programmatically define new regions. The system copies the functionality of custom region definition by allowing selection from predetermined templates, thereby maintaining versatility while significantly reducing programming complexity.
2Loss of information
If entire image data is transmitted, then complete image information is preserved, but data transmission volume and processing load increase
Solution Approach 1:
The patent applies extraction by selectively transmitting only the data corresponding to the identified regions of interest from the complete image. The imaging device extracts and transmits only the necessary portions (e.g., specific tiles or blocks) rather than the entire image data. This resolves the contradiction by maintaining information completeness for the areas that matter while significantly reducing overall data transmission volume and processing load.
Solution Approach 2:
The patent uses segmentation by dividing the image into discrete regions or tiles and selectively transmitting only the segments corresponding to regions of interest. This allows the system to transmit minimal necessary data while preserving complete information for the selected areas, thereby reducing data volume without sacrificing information completeness for the required portions.
3Ease of operation
If region selection instructions are simplified, then ease of operation is improved, but precision in region definition may be reduced
Solution Approach 1:
The patent applies preliminary action by pre-defining regions with specific characteristics (such as center points, sizes, and shapes) before operation. Users can then select from these pre-configured regions using simple instructions rather than defining them precisely themselves. This maintains operational simplicity while ensuring sufficient precision through the pre-established regional parameters that are optimized for the application.
Data Source
AI summary
An imaging device has a plurality of predefined regions of interest. The predefined regions of interest may be selected or deselected. Image data from selected regions of interest is transmitted to a host. In some embodiments the regions of interest comprise tiles. A set of selected tiles may be identified by a bit vector. An example application provides a digital camera configured to provide predefined regions of interest. The camera may be configured to permit a host to select or deselect the regions of interest.
