Dual Imaging Signal Processing for Wide Conversion Lens Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices that use two imaging units with different viewing angles, such as wide and tele lenses, struggle to generate high-quality images and perform various processing tasks efficiently, as they lack the capability to adapt signal processing based on the attachment of a wide conversion lens.
Innovation Solution
An image processing device and method that includes a wide image capturing unit, a tele image capturing unit, and an image processing unit capable of detecting the attachment of a wide conversion lens, which executes different signal processing modes such as high-sensitivity, HDR, or high-resolution image generation based on the detection result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different signal processing is executed based on wide conversion lens attachment detection, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic signal processing by detecting whether a wide conversion lens is attached to the tele image capturing unit, and automatically switching between different processing modes (wide image processing when lens is attached, tele image processing when lens is detached). This dynamic adaptation resolves the contradiction by optimizing image quality for each configuration without requiring permanently complex processing circuits for all scenarios.
Solution Approach 2:
The patent changes processing parameters based on the lens attachment state. When the wide conversion lens is attached, the system switches to wide image processing mode with corresponding parameter adjustments; when detached, it uses tele image processing mode. This parameter-based adaptation allows the system to achieve high image quality for both wide and tele configurations without permanently increasing device complexity.
2Area of moving object
If a wide conversion lens is attached to the tele image capturing unit, then the viewing angle is improved, but the device structure becomes more complex
Solution Approach 1:
The tele image capturing unit serves multiple functions: it can capture tele images with its native telephoto lens, or capture wide images when the wide conversion lens is attached. This multi-functionality allows the system to achieve both wide and tele viewing angles without requiring permanently complex structures, as the same hardware configuration adapts to different requirements through lens attachment/detachment.

AI summary
Provided is an image processing device that includes a wide image capturing unit which captures an image of a wide viewing angle, a tele image capturing unit which captures an image of a narrow viewing angle, and an image processing unit which receives an input of the captured images of the respective imaging units and executes signal processing. In a case where a wide conversion lens is attached to the tele image capturing unit, the image processing unit executes any one of a high-sensitivity image generation processing, a HDR image generation processing, or a high-resolution image generation processing based on the captured images of the wide image capturing unit and the tele image capturing unit according to a situation at the time of imaging with a wide conversion lens attachment detection unit which detects whether the wide conversion lens is attached.
