Accumulated-Pixel Frame Generation for Flexible Image Processing

Solution Overview

Problem

Current digital signal processing (DSP) methods for image quality enhancement in cameras require setting a block, which is time-consuming and inflexible, leading to inefficient image processing and limited ability to adapt to changing image areas or moving subjects.

Innovation Solution

An image processing method that generates an image quality processing-dedicated frame by calculating accumulated-pixel values within a quadrangular area, allowing for flexible region of interest settings without the need to repeatedly set blocks, thereby reducing processing time and improving image quality accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed block is set in an image for image quality processing, then the processing structure is simple and stable, but the processing time increases and flexibility is reduced

Engineering Contradiction:

Improveflexibility of block settingVSAvoidimage processing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent pre-calculates and stores accumulated pixel values for all possible blocks before image quality processing. This preliminary action allows the system to quickly retrieve pre-computed data without performing time-consuming block setting and pixel summation during the actual quality enhancement process, thereby reducing processing time while maintaining flexibility in block selection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent enables dynamic block selection based on image content and processing requirements. Instead of using a fixed predetermined block, the system can adaptively choose different blocks from pre-calculated accumulated values, allowing flexible adjustment of processing regions without incurring the time penalty of real-time block configuration.

Inventive Principle:

Principle #15Dynamics
