Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed through after-treatment using depth information, then depth-dependent blurring effect is achieved, but real-time image displaying or video capturing cannot be performed
Solution Approach 1:
The patent applies depth information to the preview image in real-time before the actual image capture. The image processor obtains depth information from multiple images, applies it to the preview image to generate a depth-dependent blurring effect, and displays the processed preview image immediately. This preliminary application of depth information enables real-time visualization without waiting for after-treatment processing.
2Loss of information
If depth information is obtained through autofocus scanning, then depth map is generated, but processing time is increased
Solution Approach 1:
The patent performs autofocus scanning to obtain depth information for the preview image, which may involve processing more data than strictly necessary for final capture. The image processor uses the obtained depth information immediately for real-time preview processing, accepting the time cost of comprehensive depth scanning in exchange for complete depth information and realistic depth effects in the preview.

AI summary
Electronic devices and methods for processing images are provided. The method includes obtaining a first image and a second image through a first image sensor, extracting depth information from at least one third image obtained through a second image sensor, applying the extracted depth information to the obtained first image and displaying the first image, and applying the extracted depth information to the obtained second image.
