Abstract

A real-time all-in-focus microscopic camera is able to display all-in-focus images as motion pictures of a high frame rate. The real-time all-in-focus microscopic camera comprises a movable focal mechanism (11A) of which focal length is changeable at a high repetition frequency, a lens driver (16) driving the mechanism (11A) to change the focal length corresponding to the repetition frequency, a high-speed imaging camera (12) imaging an object through the movable focal mechanism (11A) at a fast frame rate that allows images to be read out a plurality of times (for example, 8 times) every repetition period corresponding to the repetition frequency, and an image processor (13) processing the images acquired by the camera (12) into all-in-focus images in real time. The resultant all-in-focus images are displayed on a monitor (15). The image processor (13) is also able to perform processing for removing a ghost resulting from the fact that a blur is caused at the peripheral portion of an object to be observed.
