Disclosed is a method for photographing a panoramic image including the steps of recognizing movement of a corresponding photographing apparatus by comparing a current real-time input image with a previous image through a motion estimation mechanism with exposure compensation, determining a time to photograph each next picture by determining whether movement in a photography direction reaches a preset threshold value, and photographing each next picture by manual or automatic operation at the determined time.

Disclosed is a method for reducing noise. The method comprises decoding a bitstream encoded with a first codec, acquiring Quantization Parameter (QP) values determined in a process of encoding the bitstream with the first codec, detecting a frame with noise by using the QP values and inputting the frame with noise to a predefined noise filter.

A method for taking a panorama mosaic photograph includes displaying a partial image of a previously taken image as a guide image on a viewer of an image to be currently taken and taking a number of images constituting the panorama mosaic photograph according to a photography operation; projecting the taken images onto a common cylindrically curved surface; and joining the projected images into a single image.

A panoramic picture photographing method permits more accurate photographing of an image, particularly a panoramic image of a subject, without additional equipment, or separate devices and hardware. The method includes projecting an image, which is successively inputted in every predetermined unit of time, to an imaginary surface having a same focal distance in photographing each image constituting a panoramic picture to obtain a projected image; confirming movement of a corresponding photographing apparatus so that the projected image is compared with a previous image in real time by using a motion estimation technique, to which exposure correction has been applied; determining a photographing time point of each image by confirming the confirmed movement of the corresponding photographing apparatus according to a photographing direction has reached a predetermined critical value; and photographing each image at the photographing time point of each image according to a passive input or automatically.

Provided are a frame conversion apparatus and method and a frame type detecting apparatus and method. The frame conversion apparatus may include a detecting unit and an inverse telecine unit. The detecting unit may determine that each data frame is a telecine frame or a progressive frame according to the rate of discrete cosine transform (DCT) operation type performed on macro blocks of the frame or the number of the macro blocks on which each type of DCT operation is performed and output frame type information. The inverse telecine unit may convert the data frames into progressive frames and output the progressive frames in response to the frame type information.
