Image Processing Method for Clear Moving Object and Speed Sense
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capturing a moving object in a photo that is clear and conveys a sense of speed is challenging, as high-speed shutters produce a blurry object and low-speed shutters result in a clear but blurry image, making it difficult to achieve both clarity and motion representation.
Innovation Solution
An image processing method that captures images at two different shutter speeds, one with a high-speed shutter for a clear moving object and background, and another with a low-speed shutter for a blurry moving object, then combines these images to generate a third image where the moving object is clear and conveys a sense of speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a high-speed shutter is used to capture a moving object, then the object image is clear, but the sense of speed is lost
Solution Approach 1:
The patent combines a first image captured with a high-speed shutter (clear object) and a second image captured with a low-speed shutter (blurry object with speed sense) into a synthesized image. The clear object from the first image is overlaid on the blurry background from the second image, achieving both clarity and speed representation simultaneously.
Solution Approach 2:
The patent segments the image into two distinct components: the object region (extracted from the high-speed shutter image) and the background region (extracted from the low-speed shutter image). This segmentation allows each region to have different characteristics - the object remains clear while the background conveys motion blur.
2Object-generated harmful factors
If a low-speed shutter is used to capture a moving object, then the sense of speed is conveyed, but the object image becomes blurry
Solution Approach 1:
The patent merges the advantageous elements of both shutter speed images: the speed sense from the low-speed shutter image's blurry background is combined with the clarity of the high-speed shutter image's object, creating a composite image that exhibits both properties.
Solution Approach 2:
The patent applies different quality characteristics to different regions of the final image: the object region maintains high clarity (from the high-speed image) while the background region exhibits motion blur (from the low-speed image). This local differentiation resolves the contradiction by allowing different parts of the image to serve different functions.
3Measurement precision
If multiple images are captured and processed to achieve both clarity and speed sense, then the photo quality improves, but the device complexity increases
Solution Approach 1:
The patent performs preliminary actions by capturing both the high-speed and low-speed images simultaneously or in rapid succession before final synthesis. The object region extraction and image combination steps are executed as predetermined processing operations, reducing the complexity of real-time decision-making during image generation.

AI summary
An image processing method is provided. The method includes following steps. Firstly, a first image is obtained by shooting photo at a first shutter speed, wherein the first image includes a first object image and a first background image, and the first object image and the first background image are clear. Next, a second image is obtained by shooting photo at a second shutter speed lower than the first shutter speed, wherein the second shutter speed is lower than the first shutter speed, the first image and the second image are obtained by shooting photo within substantially the same shooting range, the second image includes a second object image and a second background image, the second object image is blurry but the second background image is clear. After that, a third image is generated from at least the first image and the second object image.
