Image processing device for generating composite images with blur
A recently granted patent (Publication Number: US11928794B2) discloses an image processing device that integrates multiple images taken at different focus positions to generate a composite image with a predetermined blur degree. The device includes a first processing unit for blurring processing, an integration unit for generating an integrated image, and a second processing unit for sharpening processing based on optical information and blur degree data. The sharpening processing is executed along the depth direction of the images, considering the optical characteristics of the system and the blur degree at the common focus position.
Furthermore, the patent includes claims for executing the blurring and sharpening processing in the frequency domain, aligning the common focus position of color components, generating composite images for stereoscopy, and performing rotation processing on images for enhanced processing. The patent also covers a non-transitory computer-readable medium storing instructions for executing the image processing steps and an image processing method for integrating and sharpening images based on optical information. Additionally, an imaging device incorporating the image processing device is described, utilizing multiple images acquired by the device's components to generate composite images with predetermined blur degrees.
