Patent ID: 7898574

Claim:
An image processor comprising: an audio data processing unit having a timer for providing audio data and information on an audio time increment; an image capturing unit configured to generate a plurality of video frames through photographing; a video data processing unit configured to generate video data and information on a video time increment using the plurality of video frames; a memory configured to store the audio data and the information on the audio time increment, and the video data and the information on the video time increment; and an error detecting unit configured to detect an error between the information on the video time increment provided from the video data processing unit and the information on the audio time increment provided from the audio data processing unit, and perform a correcting operation regularly, wherein the error detecting unit subtracts a sum of a plurality of audio time increments from a sum of a plurality of video time increments, then divides a subtraction value by the number of frames for a correction period to detect the error.
