Abstract: An endoscope processor includes a processor that can be connected to an endoscope including a moving mechanism of a focusing lens included in an objective optical system and an image pickup apparatus. The processor is configured to determine whether or not a transition has been made from a screening state to a proximity state based on positional information of the focusing lens and an image in a proximity determination mode when a variation in an image height in an effective image range with control of the moving mechanism is 1% or less, and when it is determined that a transition has been made to the proximity state, the processor is configured to end the proximity determination mode and control the moving mechanism in an autofocus mode.

Abstract: A communication apparatus which communicates with an external apparatus by receiving a communication request transmitted from the external apparatus based a call-out number uniquely allocated to the communication apparatus, includes: a communication request receiver which receives identification information allocated to the external apparatus and the communication request independently of a call-out number of the external apparatus; a display which displays information; an information storage which stores an association table associating the identification information of the external apparatus with apparatus information used for displaying in reception of the communication request from the external apparatus; and a display controller which, when the communication request receiver receives a communication request with identification information, displays apparatus information recorded in the association table stored in the information storage on the display, which is associated with identification information
