Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods struggle to handle data efficiently in subsequent processing, particularly when security processing is applied to large datasets, leading to difficulties in data handling and transmission.
Innovation Solution
A data processing device and system that perform security processing for each designated group of data within a frame, allowing for efficient framing and transmission of data to a host device, thereby improving data handling and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security processing is performed for the entirety of data from frame start to frame end, then security coverage is improved, but data handling difficulty increases
Solution Approach 1:
The patent divides the frame data into multiple groups (first group, second group, third group) and performs security processing on each group separately. This segmentation allows security coverage to be maintained while improving data handling efficiency, as each group can be processed and transmitted independently without requiring handling of the entire frame as a single unit.
2Productivity
If all data types are transmitted in one frame, then transmission efficiency is improved, but security processing complexity increases
Solution Approach 1:
The patent segments different data types (image data, image plane phase difference data, luminance data) into separate groups within the frame structure. Each group is assigned unique identification information, allowing efficient transmission of multiple data types while simplifying security processing through group-based handling rather than frame-wide processing.
Solution Approach 2:
The patent introduces identification information as an intermediary element that distinguishes between different data groups. This intermediary allows the system to efficiently manage and process multiple data types without increasing security processing complexity, as the identification information enables targeted processing of specific groups.
3Reliability
If security processing is performed on large datasets, then security coverage is improved, but transmission and handling efficiency decreases
Solution Approach 1:
The patent divides large datasets into smaller manageable groups (first group with image data, second group with phase difference data, third group with luminance data). This segmentation maintains comprehensive security coverage across all data while improving transmission efficiency, as smaller grouped data can be processed and transmitted more efficiently than large monolithic datasets.

AI summary
The present disclosure relates to a data processing device, an imaging system, and a distance measuring system that enable more suitable transmission of data.A security processing unit performs security processing for each group including designated data among a plurality of types of data for one frame obtained from a sensor chip, and a transmission unit frames data acquired by the security processing by the security processing unit and transmits the data to a host device. Then, the group is set according to a unit of data read from a memory that temporarily stores the data transmitted from the transmission unit in a host device. The present technology can be applied to, for example, an imaging system and a distance measuring system.
