1. A signal processing apparatus comprising:
- a video signal producing means for producing a standard video signal by processing an image signal representing an image of an object to be imaged;
a movement detecting circuit for detecting a movement quantity which quantatively represents movement of said object from said video signal;
an external output terminal for receiving said video signal and for outputting said video signal outside of said signal processing apparatus; and
an outline enhancing means, provided between said movement detecting circuit and said external output terminal, for enhancing an outline of the image.

9. An electronic endoscope apparatus comprising:
-
an electronic endoscope provided with an elongate insertable part, an objective optical system provided on a tip part side of said insertable part and forming an image of an object, an image device photoelectrically converting the image based on said objective optical system and an illuminating light emitting means for emitting an illuminating light from the tip part side of said insertable part; a driving signal outputting means for outputting a driving signal to output an image signal from said imaging device; a video signal processing means having an image storing means for temporarily storing said image signal as a still picture and producing a standard video signal from said image signal; a displaying means for displaying said standard video signal on a monitor; a movement detecting circuit formed of a plurality of difference signal producing means for producing difference signals representing a change of a level of respective plural image signals representing images of the object imaged at different times by said imaging means, a correlation detecting means for detecting the correlation of a plurality of difference signals and a quantifying means for quantifying the signal output detected by said correlation detecting means; and an outline enhancing means, provided between said movement detecting circuit and said displaying means, for enhancing an outline of the image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
