Abstract: An image signal scan-converting method and apparatus are disclosed. A progressive scan photographing unit receives an optical signal and outputs a progressive scan signal, converting the optical signal into an electrical signal. A first storing unit stores odd pixels of the progressive scan signal, a second storing unit stores even pixels of the progressive scan signal, and an adding unit adds the odd pixels and the even pixels read from the first and the second storing units to form an odd field and an even field, thus producing an interlaced scan signal. Accordingly, image signals formatted according to a progressive scan method are converted into image signals of an interlaced scan type, thereby allowing an image signal apparatus to be compatible with interlaced scan type processing apparatuses and improving image quality in other progressive scan type processing apparatuses.

Abstract: Disclosed is an optical filter switching apparatus used in an optical instrument for converting externally input image information into video image information and outputting the video image information. The apparatus comprises: an optical filter holding section holding a first optical filter and a second optical filter; an actuator having a rotary solenoid which rotates between a first position and a second position. A rotational power transmission section transmits the rotational force of the rotary solenoid to the optical filter holding section; and a microprocessor controls the rotary solenoid of the actuator in accordance with at least one external input signal and the power level of the video image information. The rotary solenoid is rotated to at least one of the first and second positions.
