摘要： PROBLEM TO BE SOLVED: To provide an electronic endoscope system which enables the simultaneous display of the normal, fluorescent and pseudo color images.
SOLUTION: In the moving picture display mode, the normal, fluorescent and pseudo color images are displayed on a monitor 60 as a moving picture. A front stage signal processing circuit 57 gets the normal image signals and the fluorescent image signals alternately stored into the second memories 58a and 58b based on a signal from a timing controller 71 and reads an image signal out of the image memory not involved in the loading to be transmitted to a post stage processing circuit 59. Using the fifth and sixth image memories 58e and 58f, the normal image signal and the fluorescent image signal existing only in one field are converted once to pseudo frame work, thereby generating a pseudo color image signal based on it. In the still picture display mode, the three images, normal, fluorescent and pseudo color images are displayed as still pictures while using the third and fourth image memories 58c and 58d, a moving picture as normal image is displayed on a slave screen.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of image quality as much as possible during reproduction of images when digital video signals are put out at a clock pulse having a frequency different from a sampling frequency. SOLUTION: An electronic endoscope comprises an image sensor 12, an analog/digital converter 22, and a pixel number converting circuit 28. The image sensor 12 generates an analog video signal from an optical image of an object and the analog/digital converter 22 converts the analog video signals from the image sensor 12 to digital video signals sequentially at a predetermined sampling frequency. The pixel number converting circuit 28 is provided with a coefficient calculating means. When the sampling frequency is higher than the clock pulse frequency, the coefficient calculating means thins out pixels and reflects the thinned pixels on the digital video signals processed by thinning out. When the sampling frequency is lower than the clock pulse frequency, the coefficient calculating means calculates a pixel number for interpolation on the basis of the digital video signals and interpolates pixels.
