    摘要: A method and apparatus may include aligning a reference image and an input image through ROI-based image alignment; detecting an ROI associated with an incompletely aligned region in the aligned image; and blending the aligned reference image and input image by using a plurality of weights which are attenuated according to a spatial distance from a boundary of the detected ROI. In addition, the method and apparatus may include aligning a reference image and an input image through image alignment based on an nth region of interest (ROI) which is detected at a previous stage; detecting another ROI associated with an incompletely aligned region in the aligned image; and blending the aligned image in the other ROI and an (n+1)th blended image, which is input from a next stage, in a region outside the other ROI, and outputting the last blended image to the previous stage.

    摘要: A high dynamic range (HDR) image generating apparatus and method is provided. The HDR image generating apparatus may set an auto-exposure time, a long exposure time, a short exposure time, and a reference exposure time. The auto-exposure time may be set to be shorter than the long exposure time, the short exposure time may be set to be shorter than the auto-exposure time, and the reference exposure time may be set to fall within a range between the auto-exposure time and the short exposure time. The image generating apparatus may obtain a first image with the long exposure time and a second image with the reference exposure time, may correct motion in the first image and adjust a dynamic range of the second image, and then may composite the resultant first and second images to generate a high dynamic range image.
