Solution Overview

Problem

Current imaging technologies face challenges in enhancing image quality, particularly in capturing moving objects, as they often require uniform readout times for all pixels, which can lead to suboptimal image resolution and frame rates.

Innovation Solution

An imaging control apparatus and method that differentiates the readout operation time for pixels based on moving object detection, allowing longer times for detection regions and shorter times for other regions, utilizing a controller to adjust the readout operation duration and frame rate accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If uniform readout time is applied to all pixels, then device complexity is reduced and operation is simplified, but image quality and resolution deteriorate

Engineering Contradiction:
Improveimage qualityVSAvoidreadout control complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by differentiating readout parameters between detection region pixels and non-detection region pixels. Pixels in the detection region (where moving objects are detected) are assigned longer readout times to capture motion details, while pixels in non-detection regions use shorter readout times. This localized differentiation improves image quality in critical areas without uniformly increasing complexity across the entire imaging device.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making readout parameters adjustable and variable based on detection results. The controller dynamically modifies readout time and frame rate parameters in response to detected moving objects, transitioning between different operational states. This dynamic adaptation allows the system to optimize image quality for moving objects while maintaining operational flexibility.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If readout time is extended for all pixels to improve resolution, then image resolution improves, but frame rate decreases and productivity reduces

Engineering Contradiction:
Improveimage resolutionVSAvoidframe rate
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies local quality by extending readout time only for pixels in the detection region where moving objects are present, while maintaining shorter readout times for pixels in non-detection regions. This selective approach improves resolution specifically where needed (in the detection region) while preserving overall frame rate and productivity by not uniformly extending readout times across all pixels.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies partial action by performing extended readout operations only on a subset of pixels (those in the detection region) rather than all pixels. This partial application of the extended readout technique achieves sufficient resolution improvement for moving objects without the excessive action of extending readout times system-wide, thereby maintaining acceptable frame rates.

Inventive Principle:
Principle #16Partial or excessive action

3Manufacturing precision

If readout operation is performed on all pixels at high frequency, then image quality is maintained, but power consumption increases

Engineering Contradiction:
Improveimage qualityVSAvoidpower consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by adjusting readout frequency and parameters specifically for pixels in the detection region versus non-detection regions. High-frequency readout is applied only where moving objects are detected and image quality is critical, while lower-frequency readout is used in non-detection regions, thereby reducing overall power consumption while maintaining image quality in essential areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies partial action by performing high-frequency readout operations only on a partial set of pixels (those in the detection region) rather than all pixels continuously. This selective high-frequency operation maintains image quality where needed while reducing power consumption by avoiding excessive readout operations in non-critical regions.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An imaging control apparatus of the present disclosure includes a controller that performs a readout operation on a plurality of pixels in an imaging device, and performs control on a basis of a moving object detection result to cause a time length of the readout operation on a first pixel to differ from a time length of the readout operation on a second pixel, the first pixel corresponding to a detection region where a moving object has been detected, and the second pixel corresponding to a region other than the detection region.
