Dual-Camera Peripheral Image Compensation for Wide-Angle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple cameras often suffer from deteriorated characteristics, such as distortion and low relative illumination, in the peripheral areas of images captured by wide-angle and ultrawide-angle cameras, leading to user discomfort.
Innovation Solution
The electronic device compensates for these deteriorated characteristics by using a second camera with a wider field of view to capture a peripheral area of the image, and a processor executes a model, such as a neural network, to combine images from both cameras, enhancing the peripheral areas of the first image.

Engineering Contradiction Analysis
1Area of moving object
If a wide-angle or ultrawide-angle camera is used to capture a broader field of view, then the field of view is improved, but distortion and illumination quality in peripheral areas deteriorate
Solution Approach 1:
The patent divides the image capture task into multiple segments by using multiple cameras with different fields of view. The first camera captures the central area with high quality, while the second camera captures the peripheral area. This segmentation allows each camera to operate in its optimal range, resolving the contradiction between wide field of view and peripheral image quality.
Solution Approach 2:
The patent merges images from multiple cameras with different fields of view into a single composite image. The processing circuitry combines the first image (central area) and second image (peripheral area) to create a final image that has both the broad field of view and high image quality throughout, eliminating the peripheral deterioration issue.
2Manufacturing precision
If multiple cameras with different fields of view are used, then image quality in peripheral areas is improved, but device complexity increases
Solution Approach 1:
The patent makes the camera system multi-functional by enabling it to capture both wide-angle and ultrawide-angle views simultaneously using multiple cameras. This universal capability allows the device to handle various shooting scenarios (peripheral shots, close-up shots, etc.) without requiring separate dedicated cameras, thus managing complexity while improving image quality.

AI summary
An electronic device includes memory, including one or more storage mediums, storing instructions, a first camera having a first field of view, a second camera having a second field of view, wherein the second camera and the first camera are disposed on a same side of the electronic device to face in a same direction, a display, and at least one processor including processing circuitry, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, based on receiving an input for obtaining an image using the first camera, control the first camera and the second camera to obtain a first image and a second image, obtain a third image, by compensating for a peripheral area of the obtained first image using the obtained second image, and store, in the memory, the third image.
