Solution Overview
Problem
Existing image processing systems consume significant electric energy during the image correction process, particularly when performing warping corrections, which can lead to increased power consumption and reduced efficiency.
Innovation Solution
An image processing system comprising a first and second image sensor, and an image processing device that includes processors and a correction circuit to generate and output images based on reference coordinates, with the ability to selectively perform warping corrections only during a designated reference time, thereby reducing power consumption.

Engineering Contradiction Analysis
1Reliability
If warping correction is continuously performed to maintain image quality, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic warping correction by activating the correction circuit only during specific time intervals (e.g., when zoom factor changes are detected) rather than continuously. The controller selectively enables the correction circuit based on timing signals, creating a periodic operation pattern that maintains image quality at critical moments while reducing power consumption during stable periods.
Solution Approach 2:
The system dynamically adjusts the warping correction operation based on real-time conditions. The controller monitors zoom factor changes and activates the correction circuit only when necessary, transitioning between active correction and standby states. This dynamic control optimizes the balance between image quality maintenance and power consumption reduction.
2Manufacturing precision
If warping correction time is extended to improve correction accuracy, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary warping correction operations during idle periods or when the device is in low-power states. By preparing correction data in advance and storing it for later use, the system can apply corrections quickly when needed without extending the actual correction time during active operation, thus maintaining accuracy while minimizing time loss.

AI summary
An image processing system may include a first image sensor, a second image sensor, and an image processing device. The image processing device may be configured to obtain a first image and a second image by respectively processing the first image data and the second image data. The image processing device may output an image based on the first image when a zoom factor of the output image is lower than a first reference value, generate a correction image by correcting locations of second reference coordinates of the second image based on first reference coordinates of the first image when the zoom factor of the output image is between the first reference value and the second reference value, and may output an image based on the second image when the zoom factor exceeds the second reference value.
