Apparatus and method for image processing

摘要

Disclosed is an apparatus for image processing including a first low pass filter (LPF) which removes high-frequency components from selection information about image data selection between a long-exposure image and a short-exposure image, a movement detector which obtains movement detection information by detecting movement from at least one of the images, a second LPF which removes high-frequency components from the movement detection information, a selector which obtains selection results by selecting one of the selection information from which the high-frequency components are not removed by the first LPF and the selection information from which the high-frequency components are removed by the first LPF, for each pixel group based on the movement detection information from which the high-frequency components have been removed, and a composer which composes the long-exposure image and the short-exposure image based on the selection results.

主权项

1. An image processing apparatus for generating a composite image, the apparatus comprising at least one processor to implement:
a first low pass filter (LPF) configured to remove high-frequency components from first selection information about image data selection between a long-exposure image and a short-exposure image for each pixel of the composite image, thereby generating second selection information; a movement detector configured to obtain first movement detection information that identifies pixels corresponding to movement captured in at least one of the long-exposure image and the short-exposure image; a second LPF configured to remove high-frequency components from the first movement detection information, thereby generating second movement detection information; a selector configured to obtain selection results by exclusively selecting one of the first selection information and the second selection information for each pixel of the composite image based on the second movement detection information; and a composer configured to generate the composite image by combining the long-exposure image and the short-exposure image based on the selection results.
