Abstract
1. 청구 범위에 기재된 발명이 속한 기술분야 :1. Field of the Invention:
화상 처리 장치에 관한 것이다.And an image processing apparatus.
2. 발명이 해결하려고 하는 기술적 과제 :2. Technical Problems to be Solved by the Invention:
광량변화에 따른 화상 데이타의 불균일성을 보상하기 위해 사용해오던 화이트 롤러를 블랙 롤러로 대처하여 음여왜곡보상 등록 모드에서 화이트 원고에 따른 음영 왜곡 보상용데이타를 저장하고, 화상 스캔시마다 상기 저장된 음영 왜곡 보상용 데이타를 이용하는 화상 처리 장치에서 화상 데이타 스캔 장치 및 방법을 제공한다.The white roller used to compensate for the nonuniformity of the image data due to the light quantity change is coped with the black roller to store the data for shading correction according to the white manuscript in the negative distortion correction registration mode, An image data scanning apparatus and method in an image processing apparatus using data are provided.
3. 발명의 해결방법의 요지 :3. The point of the inventive solution:
원고의 급지용으로 사용되는 롤러와, 상기 롤러와 밀착되어 원고의 독취용으로 사용되는 센서부와, 상기 센서부로 부터의 아날로그 신호를 디지탈 신호로 처리하는 화상 처리부와, 메모리를 구비한 화상 처리 장치에서, 화상 데이타를 스캔 하기 위한 제어 방법은 음영 왜곡 보상 등록 모드에서, 상기 롤러와 상기 센서부에 삽입된 화이트 원고를 독취하여 생성된 음영 왜곡 보상용 데이타를 이용하여 흑백 결정 레벨을 검출하여 상기 저장하는 과정과, 스캔 모드에서 상기 화상 처리부에서 인가되는 데이타를 상기 흑백 결정 레벨에 의거 흑백 데이타를 생성하는 과정으로 이룬다.An image processing unit for processing an analog signal from the sensor unit into a digital signal; and an image processing unit including a memory, , A control method for scanning image data includes a step of detecting the monochrome crystal level by using the data for shading distortion compensation generated by reading the white document inserted into the roller and the sensor unit in the shading correction registration mode, And generating black-and-white data based on the monochrome determination level in the image processing unit in the scan mode.
4. 발명의 중요한 용도 :4. Important Uses of the Invention:
초기에 음영 왜곡 보상 데이타를 백업시켜 스캔시마다 참조하기 위해 이를 구현한다.The shading distortion compensation data is initially backed up and implemented to refer to each scan.
