摘要： An imaging apparatus having an imaging device for imaging an object in cooperation with an endoscope is connected to a video processing unit for producing a standard video signal so that it can be disconnected freely. A signal delay occurs over a signal line linking the imaging device and the video processing unit. For this reason, a timing generator and a phase adjustment circuit are incorporated in the imaging apparatus. The timing generator generates driving signals used to drive the imaging device, and the phase adjustment circuit adjusts the phases of the driving signals so that an output signal of the imaging device will be input to the video processing unit according to predetermined timing. Even when the signal line has a different length from any other or the imaging device offers a different number of pixels from any other, the difference can be readily coped with owing to the imaging apparatus. This leads to alleviation of a load incurred by the video processing unit.

摘要： In an endoscopic imaging system, a signal representing an object image produced by a scope and projected by a camera head is processed by a CCU and displayed as an endoscopic image on a TV monitor. The object image is stored as digital image data on a memory in the CCU, read as image data of a still image, and recorded on a PC card mounted in a PC card slot. The PC card slot is formed in the front panel or the like of the CCU. A lid member or the like functioning as an anti-liquid invasion member and shield can be located at an opening of the slot.

摘要： In an endoscopic apparatus, when the dynamic range expansion on/off switch is turned on, a CPU changes a switch from one contact over to another. Red, green, and blue digital signals sent from a knee and gamma circuit are output to respective dynamic range expanding circuits. Thus, the dynamic ranges for the digital signals are expanded. On the other hand, when the CPU changes another switch from one contact over to the other, a light adjustment signal output from an operational amplifier is then driven to a level causing a diaphragm in a light source unit to open further. Consequently, an increased amount of illumination light is supplied to the incident end of a light guide running through an endoscope. Thus, when a dynamic range is expanded, a halation effect will not occur in imaging of an object located at a point near the distal end of the endoscope. Moreover, insufficiency of illumination light will not occur in the imaging of an object located at a point far from the endoscope distal end. The dynamic range can therefore be expanded efficiently. An endoscopic image of the interior of a body cavity can be viewed with the body cavity set to a desired brightness level all points ranging from a near point to a far point within the body cavity.
摘要翻译：在内窥镜装置中，当动态范围扩大开/关开关打开时，CPU将开关从一个触点切换到另一个触点。从膝盖和伽马电路发送的红色，绿色和蓝色数字信号被输出到相应的动态范围扩展电路。因此，扩展了数字信号的动态范围。另一方面，当CPU将另一个开关从一个触点切换到另一个触点时，从运算放大器输出的调光信号被驱动到导致光源单元中的隔膜进一步打开的水平。因此，向穿过内窥镜的导光体的入射端供给增加量的照明光。因此，当动态范围扩大时，在位于内窥镜远端附近的物体的成像中不会发生晕影效果。此外，在位于远离内窥镜远端的点的物体的成像中不会发生照明光的不足。因此可以有效地扩展动态范围。体腔内部的内窥镜图像可以被观察到，其体腔被设置为期望的亮度级别，其范围从体腔内的近点到远点。

摘要： One expansion substrate or a plurality of expansion substrates that realize different facilities can be connected to a main substrate that realizes basic processing to be performed by a CCU. Based on an ID number produced by an ID generation unit mounted on a connected expansion substrate, a CPU incorporated in the CCU identifies the facility realized with the expansion substrate. A menu screen image presents item BOD Control under which the facilities are presented. When item BOD Control is designated, a BOD Control screen image that lists control items indicating the facilities realized with all the expansion substrates that are connected to the main substrate is displayed. When a concrete facility such as a P-in-P facility realized with an expansion substrate is selected or designated in the BOD Control screen image, a screen image concerning the designated P-in-P facility is displayed. Thus, the details of a facility that is realized with a connected expansion substrate can be set easily.

摘要： An object is imaged continuously during a first exposure time and a second exposure time shorter than the first exposure time. Weights, one of which decreases monotonously and the other of which increases monotonously, are applied to first and second resultant image signals under the condition that the sum of the weights is 1. The first and second image signals that have been weighted are added up, thus producing a synthetic picture signal. When a luminance level is low, the ratio of the first image signal, which has been produced during the longer exposure time, to the second image signal is increased. This results in an image demonstrating a high signal-to-noise ratio. When the luminance level is high, the ratio of the second image signal, which has been produced during the shorter exposure time, to the first image signal is increased. This results in a synthetic image that proves a wide dynamic range, depicts a smoothly varying brightness level, and exhibits a characteristic of being seen as almost natural. Moreover, the first and second image signals are produced to resemble those produced during mutually different exposure times by controlling an amount of light incident on an imaging device or by varying an amount of illumination light.
