Imaging apparatus, client apparatus, imaging system, method for controlling imaging apparatus, method for controlling client apparatus, and method for controlling imaging system for controlling sensitivity using the insertion and retraction of an infrared cut filter into and from an optical path

摘要

An imaging apparatus connectable to a client apparatus via a network includes an imaging optical system, an image sensor, an infrared cut filter (IRCF) driving circuit that inserts and retracts an IRCF into and from an optical path of the imaging optical system, and a communication circuit that receives, from the client apparatus, an automatic insertion and retraction control command for causing the imaging apparatus to automatically control insertion and retraction of the IRCF and additional information about insertion and retraction of the IRCF. The communication circuit transmits, to the client apparatus, operation information indicating which of cases the imaging apparatus uses the additional information received by the communication circuit. The cases include a case where the IRCF is inserted into the optical path, a case where the IRCF is retracted from the optical path, and both the cases where the IRCF is inserted and where the IRCF is retracted.

主权项

1. An imaging apparatus that communicates with an external apparatus via a network, the imaging apparatus comprising:
an imaging optical system; an infrared cut filter that cuts off infrared light; an image sensor configured to capture an image of an object formed by the imaging optical system; and at least one processor that operates to: insert and retract the infrared cut filter into and from an optical path of the imaging optical system; increase gain of a video signal output from the image sensor by use of a means other than retracting the infrared cut filter from the optical path of the imaging optical system; receive, from the external apparatus via the network, an adjustment command in which adjustment information about insertion and retraction of the infrared cut filter is described, the adjustment information being describable separately or in common for a case where the infrared cut filter is inserted into the optical path and a case where the infrared cut filter is retracted from the optical path; and control the increase of the pain of the video signal and the insertion and retraction of the infrared cut filter at respectively different timing based on the adjustment command received by the at least one processor.
