Solution Overview

Problem

Conventional camera systems in electronic devices, such as smartphones, have limited viewing angles and often produce distorted images when using wide-angle lenses, making it difficult for users to capture images with intended perspectives without manual adjustment.

Innovation Solution

An image photographing apparatus with two rotatable cameras and a controller that calculates the distance to an object and adjusts the viewing angle to ensure the object is centered and within the frame, allowing for dynamic adjustment of the viewing angle based on the distance and object location, using pre-stored settings for optimal image capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camera with a wide viewing angle is used, then the viewing angle is improved, but image distortion occurs

Engineering Contradiction:
Improveviewing angleVSAvoidimage distortion
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent divides the camera system into multiple cameras (at least two cameras) with different viewing angles. Each camera captures images from its specific angle, and the system selectively uses appropriate cameras based on shooting scenarios. This segmentation allows the system to achieve wide viewing angle coverage without any single camera producing distorted images, as each camera operates within its optimal angular range.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a special lens such as a fisheye lens is used to widen the viewing angle, then the viewing angle is improved, but image distortion increases

Engineering Contradiction:
Improveviewing angleVSAvoidimage distortion
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Instead of using a single fisheye lens that produces distorted images, the patent segments the imaging function across multiple cameras with different lens characteristics. Each camera uses a standard lens with acceptable distortion characteristics, and the system achieves the wide viewing angle effect by selecting and combining images from multiple cameras positioned at different angles, thereby avoiding the distortion inherent in fisheye lenses.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a multi-functional camera system where each camera serves multiple purposes: capturing images at different viewing angles, providing backup coverage, and enabling flexible scene composition. The system can selectively activate appropriate cameras based on the shooting scenario, making the camera module universally adaptable to various photographing needs without requiring specialized distorted lenses.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Volume of moving object

If the camera size is reduced to fit in small electronic devices, then the device size is improved, but the viewing angle is limited

Engineering Contradiction:
Improvecamera sizeVSAvoidviewing angle
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a single-camera approach to a multi-camera spatial arrangement. By positioning multiple cameras at different angular positions around the device, the system achieves a wider effective viewing angle coverage without increasing the size of individual cameras. This dimensional change in camera layout allows small electronic devices to incorporate cameras with collectively broader viewing angles while maintaining compact individual camera units.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
