Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transmission systems face challenges in handling high dynamic range rendering for partial regions of interest (ROI) segmented from captured images, particularly in efficiently transmitting and processing image data to avoid system shutdowns during bulk data transmission.
Innovation Solution
A transmitting apparatus and receiving apparatus are designed to acquire and process high dynamic range information for ROI, sending image data as payload and ROI information as embedded data, enabling high dynamic range rendering by conforming to specific rendering conditions and using MIPI standards for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high dynamic range information for ROI is transmitted as separate data, then rendering quality is improved, but transmission data volume and processing complexity increase
Solution Approach 1:
The patent segments the image into multiple regions of interest (ROIs) and transmits high dynamic range information only for these segmented regions rather than for the entire image. This segmentation approach maintains high rendering quality for important regions while significantly reducing the overall transmission data volume by excluding non-ROI areas from high dynamic range processing.
Solution Approach 2:
The patent applies high dynamic range information locally only to ROI regions rather than uniformly across the entire image. By embedding ROI information (coordinates, size, exposure conditions) with the image data, the system enables selective high dynamic range rendering only where needed, improving rendering quality for critical areas while minimizing data transmission requirements.
2Measurement precision
If high dynamic range rendering is performed for entire captured images, then rendering quality is improved, but processing load and power consumption increase
Solution Approach 1:
The patent divides the captured image into multiple regions of interest and performs high dynamic range rendering only for these segmented regions. By identifying and processing only the ROI portions rather than the entire image, the system maintains high rendering quality while significantly reducing computational processing load and associated power consumption.
Solution Approach 2:
The patent applies high dynamic range rendering partially only to necessary ROI regions rather than performing the computationally intensive process on the entire image. This partial action approach ensures sufficient rendering quality for important areas while avoiding the excessive power consumption that would result from processing all pixels in the captured image.
3Measurement precision
If multiple ROIs are transmitted with individual high dynamic range information, then rendering precision is improved, but transmission complexity increases
Solution Approach 1:
The patent merges multiple ROI information sets into a unified transmission structure. By combining coordinates, sizes, and exposure conditions for multiple ROIs into a single embedded data structure that accompanies the image payload, the system maintains high rendering precision for each ROI while reducing transmission complexity compared to sending separate data streams for each region.

AI summary
It is an object to realize high dynamic range rendering of a partial region of interest (ROI) segmented from a captured image. A transmitting apparatus includes a controlling section that controls the acquisition of high dynamic range information as information for use in the high dynamic range rendering of image data of a ROI (Region of interest), and a transmitting section that sends out the image data of the ROI as payload data and sends out ROI information as embedded data.
