In a video signal transmitting device, a basic image generation unit extracts, for each of the color signal component, pixels constituting a frame of the color signal component at a uniform interval two-dimensionally and two-dimensionally arranges the extracted pixels in a prescribed arrangement to generate a prescribed number of color signal basic images. A basic stream generation unit extracts, for each of the color signal basic images, pixels of the color signal basic image generated by the basic image generation unit in a prescribed sequence to generate a basic stream. A link signal generation unit synthesizes a prescribed number of basic streams in the same or different color signal components generated by the basic stream generation unit, encodes bit-length units of the synthesized basic streams to a different bit length, and generates a link signal having a prescribed speed.

A contour compensation circuit that generates a contour-compensated signal by which a signal level of a contour of the object is emphasized, from an image signal obtained by an image pickup of an object. This circuit includes a reverse gamma controller, a contour compensation signal generator, and a calculator. The reverse gamma controller determines a standard channel from among the channels constituting the image signal, and obtains a liner standard channel from the standard channel by the reverse control. The contour compensation signal generator generates a contour compensation signal from the liner standard channel. The control signal generator computes a comparative value from the liner standard channel and the contour compensation signal, and generates a control signal based on a comparison between the comparative value and a threshold value. The calculator computes the contour-compensated signal based on the contour compensation and control signals, and the liner standard channel.

A process for taking a slow motion picture is disclosed which comprises: setting a plurality of cameras each having a shutter so that each of them can take an image with a similar view; and continuously taking fields of a subject by said a plurality camera in a timely staggered manner. In this process, timing of opening the shutter of each camera is staggered so that each camera takes a picture timely staggered, and a time for opening the shutter of each cameras is set to be a shorter than one field time of said each camera. Also, disclosed is an apparatus for taking a slow motion picture, which comprises: a plurality of cameras each having a shutter, arranged so that each of them can take an image with a similar view; means for setting the opening time of the shutter, which sets the timing for opening the shutter of each camera to be staggered so that each camera takes a picture timely staggered, and which makes the picture taken by each camera shorter than one field time of said each camera; and a recorder which records the pictures taken by each camera.
