Abstract: Provided are a depth information based optical distortion correction (ODC) circuit and method. The ODC circuit includes a depth acquisition unit acquiring a depth of an image, a grid generation unit dynamically generating a correction grid corresponding to the depth of the image using depth information of the image and a projection matrix, and a distortion correction unit correcting optical distortion in the image using the correction grid. The corrected image can then be stored, transmitted, or otherwise output. The image can be a single static image or photograph or a frame in a video recording.

Abstract: An image processing device includes an image segmentation unit, a stitching unit and a rendering unit. The image segmentation unit divides a plurality of input images into a plurality of first images and a plurality of second images based on color information and depth information. The plurality of input images are sequentially captured. The stitching unit generates a first panoramic image by synthesizing the plurality of first images, and generates a second panoramic image by synthesizing the plurality of second images. The rendering unit generates an output panoramic image based on the first panoramic image and the second panoramic image.
