Abstract: A method for photographing a panorama picture is provided to correct and adopt an image obtained by a camera by considering the relation with a real image of a subject so that the movement of a camera can be recognized accurately. When photographing each image which configures a panorama picture, a projected image is obtained by projecting an image, which is continuously inputted at a predetermined time interval, onto a virtual plane(200-215). A motion of a corresponding photographing device is detected by comparing a current image with a previous image based on a motion estimation technique by which exposure calibration is applied to the projected image(220). The photographing point for each image is judged by confirming, according to the movement of the detected motion of the corresponding photographing device, that the motion depending on photographing direction reaches a threshold value(230,240). Each image is inputted manually or is photographed at each photographing point of each image(250).

Abstract: A method for capturing a panorama mosaic image in a mobile terminal is provided to perform mosaic configuration with a relatively simple calculation by using limited hardware resources. A portion of a previously captured image is displayed as a guide image on an LCD(Liquid Crystal Display) viewer of a currently captured image and a plurality of images constituting a mosaic image is captured according to user manipulation(30). When the captured image is obtained in a panorama mode, projection transformation can be approximated to a rotational transformation matrix and each image is re-projected to a common cylindrical curved surface(32). Overlapped images of the re-projected images are locally aligned to determine an optimal position by using a hexagonal search scheme(34). Image stitching is performed on the overlapped regions by using a dynamic programming scheme to determine a boundary for connecting the overlapped images most naturally(36). A blending process is performed by removing a sudden change of brightness and the color sense based on the boundary region of the images(38).

Abstract: An apparatus and a method for detecting a telecine frame from a compressed bitstream are provided to detect a frame type in real time by detecting the frame type in accordance with the number of macro blocks which use a DCT(Discrete Cosine Transform) method. In a detection process, it is determined whether each frame of data is a telecine frame or a progressive frame in accordance with a ratio of a DCT method used in macro blocks included in the frame or in accordance with the number of the macro blocks which use the DCT method, and frame type information is outputted. In a reverse telecine process, the frame of the data is converted into the progressive frame to be outputted. In the detection process, it is determined whether the frame is the telecine frame or the progressive frame in accordance with a ratio of a field DCT method used in the macro blocks included in the frame or in accordance with the number of the macro blocks which use the field DCT method, and the frame type information is outputted.
