IMAGING APPARATUS, CLIENT APPARATUS, IMAGING SYSTEM, METHOD FOR CONTROLLING IMAGING APPARATUS, METHOD FOR CONTROLLING CLIENT APPARATUS, AND METHOD FOR CONTROLLING IMAGING SYSTEM

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 insertion and retraction unit configured to insert and retract the infrared cut filter into and from an optical path of the imaging optical system; an image sensor configured to capture an image of an object formed by the imaging optical system; a sensitivity increasing unit configured to 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; a reception unit configured to 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 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 a control unit configured to control the sensitivity increasing unit and the insertion and retraction unit at respectively different timing based on the adjustment command received by the reception unit.
