Abstract:
An endoscope apparatus capable of transmitting an endoscope image as an optical signal includes: an electronic component that includes a reception circuit configured to receive an electric signal outputted from an image pickup device and supply the electric signal to a conversion device; a printed board provided with the electronic component; a shielding member that covers at least the reception circuit; a first path via a ground connection line that is provided for the electronic component, and electrically connects the shielding member to a ground; and a second path via a conductive portion that electrically connects the shielding member to the ground, wherein an impedance of the second path is lower than an impedance of the first path.
Abstract:
An image pickup apparatus is provided with: an objective optical system; an image pickup device; a contrast AF section adjusting a focus so that a peak value of a contrast evaluation value of an image is taken; an amount-of-motion detecting section detecting, from a plurality of time-series images, amounts of motion of the subject; and a control section controlling the contrast AF section so as to calculate another contrast evaluation value in a region where a region to be excluded where an amount of motion is equal to or larger than a threshold is excluded from a calculation target region, and the contrast AF section corrects the other contrast evaluation value based on an area of the calculation target region and an area of the region where the region to be excluded is excluded from the calculation target region.
Abstract:
An endoscope apparatus includes: a first discrimination section configured to be connectable to a first endoscope including a communication circuit and capable of transmitting image pickup device type information, and a second endoscope including a resistance configured by a resistance value for enabling identification of a mounted image pickup device and corresponding to the image pickup device, and configured to acquire information for identifying a type of an image pickup device from a connected endoscope to determine a type of the connected endoscope; and an image pickup communication reception section configured to receive the image pickup device type information from the communication circuit when it is determined in the first discrimination section that the first endoscope is connected.
