て決して劣らぬ特徴を備えている。Conventionally, an endoscope using a television camera has been proposed as an imaging device. Many of them are installed. However, with the recent advances in electronics technology, cameras have been proposed that use devices called solid-state image sensors instead of image pickup tubes as the photoelectric conversion means of television cameras, and endoscopes have also been replaced with conventional cameras. Instead of an image guide in which optical fiber bundles are precisely aligned, it has been proposed to arrange them in the focal plane of an imaging optical system. In addition to characteristic features such as no afterimage and no deterioration in peripheral resolution, solid-state image sensors are lightweight, compact, consume low power, have a long lifespan, and are highly reliable, making them superior to conventional optical fiber bundles. It has features that are in no way inferior.

The endoscope, of which only the distal end 11 is shown in the figure, holds a photographing optical system 12, and on its imaging surface there is a picture of element 13 of solid-state image sensing elements 13 and 14 integrated into the back plate. A bare surface is placed on the imaging plane. The solid-state image sensor 13 has a so-called micro color filter in the form of, for example, a red, edge, and blue lattice, and has a function of converting an optical signal forming the subject area into a color signal, and the solid-state image sensor 14 - It is assumed that it is provided only to capture the optical image of the object as a single 1/c91i dark image and to form a luminance signal. These integrated solid-state image sensors are
Although not shown, the pixel surface of the solid-state image sensor 13 or 14 is rotated electromagnetically or mechanically by an operation from the operating unit at hand, so that the pixel surface of the solid-state image sensor 13 or 14 is aligned with the image-forming surface of the imaging optical system 12 as necessary. made to be relative. When a color signal for a color image is output from the solid-state image sensor 13, the switch S
W is closed, so the green light component signal is input from the signal processing circuit 16 to the NTSC color encoder 11 via the preamplifier 15, and is input as an NTST color signal (luminance signal) to a color monitor (not shown). .

得られることとなる。Further, when the solid-state image sensor 14 is not close to the image forming surface of the lens 12, the switch SW is open, and therefore the photoelectric signal from the solid-state image sensor 14 is transmitted to the preamplifier 15,
The signal processing circuit outputs only 16 directions! Only black and white image signals will be output. In this case, the solid-state image sensor 1
Since the number of picture elements 4 is the same as the number of picture elements of the solid-state image sensor 13, the effect of increasing the sensitivity by about three times is obtained.
