Solution Overview

Problem

Conventional video systems require separate interfaces and streams for different levels of video processing, leading to increased cost, power consumption, and complexity, whereas they can benefit from a single interface to output multiple video streams with varying levels of processing.

Innovation Solution

A method and system that utilize a single parallel digital video interface to output a 'super frame' containing both raw and contrast-enhanced video streams from a thermal camera core, allowing for dual video streams of different bit depths to be transmitted efficiently without additional hardware, using a focal plane array, non-uniformity correction, automatic gain control, and color conversion modules to process and frame the data.

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple video streams with different processing levels (raw and contrast-enhanced) into a single parallel digital video interface using a super frame structure. This merging approach eliminates the need for separate interfaces while maintaining both video quality levels, directly resolving the contradiction between processing quality and interface complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single parallel video interface is designed to universally handle multiple types of video data streams simultaneously. The interface can transmit both raw imaging data and processed display data through the same channel, making it multi-functional and eliminating the need for dedicated interfaces for each processing level.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 1:

The patent merges the functionality of multiple video output interfaces into a single parallel video interface that can handle multiple data streams. This reduces hardware component count, simplifies manufacturing, and lowers overall system cost while maintaining versatile video output capabilities for different processing levels.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single interface design provides universal support for multiple video stream types, eliminating the need for multiple specialized interfaces. This multi-functionality reduces hardware requirements and manufacturing complexity while maintaining adaptability for different video processing needs.

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent segments the video data into distinct super frames, with each super frame containing both raw imaging data and processed display data in an organized structure. This segmentation approach manages data transmission complexity by providing clear data organization and separation within the single interface stream.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The super frame structure acts as an intermediary organization layer that manages multiple video streams within a single interface. It provides a standardized container format that simplifies the transmission of complex multi-stream data by establishing clear data boundaries and organization rules.

AI summary

A method of operating a video camera includes capturing a scene of imaging data using a focal plane array (FPA) module of the video camera. The scene of imaging data is characterized by a first bit depth. The method also includes processing, using an image processing module coupled to the FPA module, the scene of imaging data to provide display data characterized by a second bit depth less than the first bit depth. The method further includes forming a super frame including the display data and the scene of imaging data and outputting the super frame.
