An addition image generation modulesequentially timewise adds images (input images) of still pictures at individual discrete time points included in a motion picture to be analyzed, thereby generating two kinds of addition images (image A and image B), respectively including images of still pictures at different discrete time points with the images being added at different ratios. Matrix development modules respectively take out pixel groups (first pixel group a(i, j) and second pixel group b(i, j)) located in a predetermined area (for example, in an area having a size of 3&#xd7;3), from the generated image A and image B. A motion detection module compares the taken out first pixel group a(i, j) and second pixel group b(i, j), to detect a motion component in the motion picture to be analyzed. A movement direction detection module compares the taken out first pixel group a(i, j) and second pixel group b(i, j), while spatially shifting these groups, to detect the movement direction in the motion picture to be analyzed.

Motion picture analyzing system

An experimental apparatus for performing observations of and experimental operations on a sliced specimen of a biological tissue is disclosed. The apparatus provides a high freedom for experimental operations and maintains the physiological activity of the sliced specimen. The experimental apparatus includes an experimental vessel for holding saline solution, the vessel is comparatively shallow, open at top, and transparent at least on a bottom. The apparatus also includes a specimen holder holding member for holding a specimen holder with a membrane filter at the bottom, taken out of a cultivator, a solution introduction tube for feeding fresh saline solution into the experimental vessel, and a solution discharge tube for sucking saline solution from the experimental vessel.
