发明名称 Electronic camera having improved support for optical low-pass filter
摘要 An electronic camera of a type employing an optical low-pass filter to eliminate moire pattern effects wherein the overall size of the camera is reduced and an optimum shutter efficiency is obtained. The camera includes, in order, an objective lens, a retractable mirror, a focal plane shutter, and an image pickup device. The optical low-pass filter is positioned between the retractable mirror and the focal plane shutter. The arrangement avoids interference with the path of the retractable mirror and prevents an increase in the distance between the focal length shutter and the image pickup device.
