EXTERNAL APPARATUS AND IMAGING APPARATUS

摘要

A focus correction setting application is connected to an imaging apparatus such that the focus correction setting application can communicate with the imaging apparatus. The focus correction setting application holds, in a focus position correction amount table with respect to various light sources, focus position correction amounts for correcting a shift in a focus position caused by inserting or removing an optical filter into or from an optical path of a lens group of the imaging apparatus, selects a light source in a window, acquires a focus position correction amount corresponding to the selected light source among the held focus position correction amounts, and controls the imaging apparatus to correct the focus position by the acquired focus position correction amount when inserting or removing the optical filter.

主权项

1. An external apparatus capable of communicating with an imaging apparatus that corrects a shift in a focus position caused by inserting or removing an optical filter into or from an optical path of an imaging optical system, the external apparatus comprising:
a selection unit configured to allow a user to select a light source for an object of the imaging apparatus; a determination unit configured to, based on a zoom position of the imaging apparatus and the light source selected using the selection unit, determine a correction amount for correcting the shift; and a transmission unit configured to transmit the correction amount determined by the determination unit to the imaging apparatus.
