IMAGE STABILIZATION APPARATUS AND METHOD AND IMAGE CAPTURING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18503303 titled 'IMAGE STABILIZATION APPARATUS AND METHOD AND IMAGE CAPTURING APPARATUS
Simplified Explanation
The abstract describes an image stabilization apparatus that calculates image stabilization coefficients based on motion vectors and shake acceleration, selects the appropriate coefficient based on the accuracy of motion vector detection, and calculates translational shake amount.
- Motion vector detector detects motion vector from images
- First calculator calculates first image stabilization coefficient based on motion vector
- Second calculator calculates second image stabilization coefficient based on shake acceleration
- Determination unit selects coefficient based on accuracy of motion vector detection
- Translational shake calculator calculates shake amount using selected coefficient
- Potential Applications:**
- Camera systems in smartphones, digital cameras, and other devices - Video stabilization software for post-processing applications
- Problems Solved:**
- Reducing blurriness and shakiness in images and videos - Improving overall image quality and clarity
- Benefits:**
- Enhanced image and video quality - Improved user experience with clearer and more stable images - Increased versatility and usability of image capturing devices
Original Abstract Submitted
An image stabilization apparatus comprises a motion vector detector that detects a motion vector from images repeatedly output from an image sensor; a first calculator that calculates a first image stabilization coefficient based on the motion vector; a second calculator that calculates a second image stabilization coefficient based on acceleration of shake of an image capturing apparatus; a determination unit that selects either of the first or the second image stabilization coefficient based on information about accuracy of detection of the motion vector; and a translational shake calculator that calculates an amount of translational shake using the first or the second image stabilization coefficient selected by the determination unit. In a case where the information indicates that the accuracy is low, the determination unit selects the second image stabilization coefficient, and select the first image stabilization coefficient otherwise.
