摘要： The movement detecting circuit of this invention has a band detecting circuit for detecting the signal components of a plurality of image signals. The output signal of this band detecting circuit is input into a band varying circuit for varying the band characteristics of the image signals. The plural image signals having had the band characteristics varied in the band varying circuit are input into a difference signal producing circuit which produces a difference signal of pixel signals approaching respective plural image signals representing the images of an object imaged at different times. A correlation amount between the corresponding plural difference signals produced by the difference signal producing circuit is detected in a correlation detecting circuit. The signal output detected in the correlation detecting circuit is quantified in a quantifying circuit.

摘要： An endoscope apparatus is disclosed in which the horizontal transfer of the charge of a solid imaging device such as a CCD and the resetting for the detection of the charge are conducted by a common drive signal. The signal transmitted from the solid imaging device is caused to contain a feed-through period by making the drive signal to be served by a multi-valued level horizontal transfer signal exceeding a trinary value. Therefore, reset noise or the like can be eliminated by processing the output signal by using a correlated double sampling circuit or the like so that a video signal exhibiting a good S/N ratio can be obtained.

摘要： There is provided a frozen picture memorizing memory holding as a frozen picture image a picture image signal imaged by an electronic endoscope. By the operation of a frozen picture directing switch, whether the frozen picture is adapted to the memorizing condition or not is judged through a picture image movement detecting circuit. In case it is judged to be adapted to the memorizing condition, the picture image signal is memorized actually as a frozen picture image to obtain a clear frozen picture having little color smear and fogging.
