Photographing apparatus and method of providing photographed video

Abstract

A photographing apparatus and a method of providing a photographed video converts a photographed video into two types of formats, stores the converted video, and transmits the video wirelessly in real-time. Therefore, a user stores a high quality video photographed by a photographing apparatus as well as broadcasts the photographed video in real-time.

 a storage unit to store at least one of the video file of the first format and the video file of the second format.   
     
     
         4 . The photographing apparatus of  claim 3 , wherein:
 the first MUX outputs the video file of the first format to the storage unit;   the second MUX multiplexes the second video stream with the audio stream, converts the multiplexed stream into a video file of the second format, and outputs the video file of the second format to the communication unit; and   the communication unit transmits the video file of the second format wirelessly external to the photographing apparatus   
     
     
         5 . The photographing apparatus of  claim 4 , wherein the video file of the first format is a video file having the same definition as the first video data photographed by the image sensor. 
     
     
         6 . The photographing apparatus of  claim 5 , wherein the video file of the first format is a video file having full high definition (HD). 
     
     
         7 . The photographing apparatus of  claim 4 , wherein the video file of the second format is a video file having capacity which is the same as or less than the capacity capable of being transmitted by the communication unit wirelessly. 
     
     
         8 . The photographing apparatus of  claim 3 , further comprising:
 a control unit to control the second MUX to perform at least one of storing the video file of the second format in the storage unit and transmitting the video file of the second format wirelessly through the communication unit according to a manipulation of a user.   
     
     
         9 . The photographing apparatus of  claim 1 , wherein the scaler adjusts the size of the first video data by performing at least one of adjusting resolution of the first video data and extracting a specific portion from the first video data. 
     
     
         10 . A method of providing a photographed video, comprising:
 photographing an object and generating first video data including the photographed object;   adjusting the size of the first video data and to generate the second video data and to output the generated second video data;   encoding the first video data and the second video data to be converted into a first video stream and a second video stream;   multiplexing the first video stream and an audio stream, and converting the multiplexed stream into a video file of a first format;   multiplexing one of the first video stream and the second video stream and the audio stream, and converting the multiplexed stream into a video file of a second format which is different with the first format; and   transmitting the video file of the second format wirelessly.   
     
     
         11 . The method of  claim 10 , wherein the converting the multiplexed stream into a video file of a second format selects one of the first video stream and the second video stream according to a manipulation of a user, multiplexes the selected video stream and the audio stream, and converts the multiplexed stream into a video file of a second format. 
     
     
         12 . The method of  claim 10 , further comprising:
 storing at least one of the video file of the first format and the video file of the second format.   
     
     
         13 . The method of  claim 12 , wherein:
 the storing stores the video file of the first format;   the converting the multiplexed stream into the video file of the second format multiplexes the second video stream with the audio stream, and converts the multiplexed stream into a video file of the second format; and   the transmitting transmits the video file of the second format wirelessly external to the photographing apparatus.   
     
     
         14 . The method of  claim 13 , wherein the video file of the first format is a video file having the same definition as that of the first video data photographed by an image sensor. 
     
     
         15 . The method of  claim 14 , wherein the video file of the first format is a video file having full high definition (HD). 
     
     
         16 . The method of  claim 13 , wherein the video file of the second format is a video file having capacity which is the same as or less than the capacity capable of being transmitted by the communication unit wirelessly. 
     
     
         17 . The method of  claim 12 , further comprising:
 controlling to perform at least one of storing the video file of the second format and transmitting the video file of the second format wirelessly according to a manipulation of a user.   
     
     
         18 . The method of  claim 10 , wherein the generating the second video data adjusts the size of the first video data by performing at least one of adjusting resolution of the first video data and extracting a specific portion from the first video data, and generates the second video data. 
     
     
         19 . A photographing apparatus comprising:
 an image sensor unit to capture moving images, convert the moving images into an electrical signal and output the electrical signal as video data;   a scaler unit to reduce the size of the video data; and   a communication unit to wirelessly transmit the reduced size video data in real time.
