Abstract: 동기검출장치가 개시된다. 본 발명의 실시예에 따른 동기검출장치는 카운팅부, 에러검출부, 및 라인길이발생부를 구비한다. 카운팅부는 클록신호에 응답하여 소정의 카운팅수까지 카운팅한다. 에러검출부는 제 1 레벨의 동기지시신호에 응답하여 상기 카운팅부의 현재 카운팅값과 이전 라인길이와의 차이를 에러로서 발생한다. 라인길이발생부는 상기 에러를 자동보정한 보정에러와 상기 카운팅수에 응답하여 현재 라인길이를 발생한다. 상기 동기지시신호는 입력신호에 포함된 동기펄스의 하강에지 또는 상승에지에서 제 1 레벨이며, 그 이외의 구간에서는 제 2 레벨이다. 본 발명에 따른 동기검출장치는 잡음 등에 의해 입력영상신호가 왜곡된 경우에도 정확하게 동기위치를 검출할 수 있으며, 반도체 공정에 있어서 면적을 줄일 수 있고 온도나 보드 상황과 같은 외부요인에 의한 성능변화를 방지할 수 있는 장점이 있다.

Abstract: A post-processing circuit is provided to perform various post-process modes through one post-processing circuit by differently post-processing an image signal according to the post-process modes. A low frequency extracting unit(110) outputs a low frequency image component of an image signal as a low frequency signal. A high frequency extracting unit(120) outputs a high frequency signal by multiplying a high frequency image component by the first gain. A middle frequency extracting unit(130) outputs a high frequency signal by multiplying a middle frequency image component by the second gain. An adding unit(140) outputs a post-processed output signal of the image signal by adding the low frequency signal, the high frequency signal, and the middle frequency signal. The first gain and the second gain are differently set according to pixels in a space area displayed by the image signal. A low frequency image component, a high frequency image component, and a middle frequency image component are differently post-processed according to purpose of post-process.

Abstract: A synchronous detection device is provided to detect line length by using an external clock irrespective of an input image signal and detect a synchronous position by using the detected line length. A counting unit(410) counts the number by a certain counting number in response to a clock signal. An error detecting unit(430) generates difference between a current counting value and previous line length as an error in response to a synchronous indication signal of the first level. A line length generating unit(450) generates current line length in response to a correction error in which the error is automatically corrected and the counting number. The synchronous indication signal has the first level in a falling edge or a rising edge of a synchronous pulse included in an input signal and has the second level in the other interval.
