摘要： An object of the present invention is to provide an image freezing signal-processing apparatus capable of eliminating a necessity of using a large number of memories, reducing a time lag and preventing an image deviation. Sequence signals for R, G and B are stored in a first memory via an A/D converter and as well as the same are supplied to a movement detection/control circuit so that an image which displays the minimum about of movement in a predetermined time passed from the freeze signal is read from the first memory so as to be written to a still picture memory. The movement detection/control circuit stops the movement detection operation in a case where the image which displays a small amount of movement is stored in the still picture memory so as to transmit the image stored in the still picture memory as a still picture in a state in which updating is inhibited. In a case where an image which displays a small amount of movement is not stored, an image which displays the minimum amount of movement in a predetermined time is transmitted as a still picture.

摘要： A movement amount detected by a movement detection circuit on the basis of an image signal corresponding to an object image is input to a minimum value detection circuit. This detection circuit sets an operation time for the detection of the minimum value by using fuzzy inference on the basis of the movement amount and the gradient amount of the movement. An image signal corresponding to the smallest movement amount in this operation time is retained in a freeze memory. In this case, the operation time is set by fuzzy inference by using the movement amount and the gradient amount as factors for fuzzy inference so that the operation time can be set automatically to a time suitable for obtaining static images possessing a small amount of movement.

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.

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： In an electronic endoscope apparatus each of the signals of a plurality of systems output from at least one solid state imaging device is judged by a signal monitoring device as to whether it is normal or not. On the basis of the judged result, the processing mode corresponding to each of the signals of the plurality of systems is changed and each signal is processed. If an abnormality occurs, an observed image with which the endoscope inspection can continue will be secured to be safe. Further, in the electronic endoscope apparatus, when the output signal from the solid state imaging device is judged to be abnormal, the amount of illuminating light will be attenuated, the danger by the excessive amount of illuminating light will be avoided and the safety of the person being monitored will be secured.
