Abstract

An apparatus includes an element configured to capture an image of an object by an optical system, a first filter disposed closer to an object side than the optical system and configured to attenuate light entering the element, at least one processor, and a memory coupled to the at least one processor and storing instructions that cause the at least one processor to set any of a first mode in which the apparatus performs imaging and a second mode in which the apparatus does not perform imaging but stands by, insert the first filter into an optical path of the element in a case where a mode is shifted from the first mode to the second mode, and remove the first filter from the optical path in a case where the mode is shifted from the second mode to the first mode.

12 . The method according to claim 11 , wherein the apparatus further includes another filter configured to attenuate light entering the element, and wherein an attenuation rate of the other filter is higher than an attenuation rate of the filter.
13 . The method according to claim 12 , wherein the other filter is disposed into an optical path of the element in the second mode and is not disposed into the optical path of the element in the first mode.
14 . The method according to claim 11 , wherein the apparatus further includes a diaphragm configured to adjust a quantity of the light entering the element, and wherein an aperture diameter of the diaphragm in the second mode is smaller than an aperture diameter of the diaphragm in the first mode.
15 . The method according to claim 11 , further comprising receiving an input for setting any of the first mode and the second mode.
16 . The method according to claim 15 , wherein the filter is controlled to increase the attenuation rate of the light in a case where the input is not received for a predetermined period.
17 . A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an apparatus, the apparatus including an element configured to capture an image of an object by an optical system and a filter configured to attenuate light entering the element, the method comprising: setting any of a first mode in which the image captured by the apparatus is distributed to another apparatus and a second mode in which the image captured by the apparatus is not distributed to the other apparatus; and controlling the filter so that an attenuation rate of the light in the second mode is higher than an attenuation rate of the light in the first mode.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Continuation of co-pending U.S. patent application Ser. No. 18/493,699 filed Oct. 24, 2023, which claims priority benefit of Japanese Patent Application No. 2022-174745, filed Oct. 31, 2022, which are hereby incorporated by reference herein in their entireties. BACKGROUND Field The aspect of the embodiments relates to an imaging apparatus, a control method, and a storage medium. Description of the Related Art In a case where sunlight condensed by a lens is applied to one portion inside a lens barrel for a long period, a resin forming the lens barrel may be thermally damaged. Japanese Patent Application Laid-Open No. 2013-142713 discusses a technique for changing an optical zoom position to a wide-angle side by a predetermined amount in a case where a predetermined time elapses after both of a camera main body and an imaging lens barrel come into an unmoved state. This prevents the light from being concentratedly applied to one portion inside the lens barrel for a long period. SUMMARY According to an aspect of the embodiments, an apparatus includes an element configured to capture an image of an object by an optical system, a first filter disposed closer to an object side than the optical system and configured to attenuate light entering the element, at least one processor, and a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to set any of a first mode in which the apparatus performs imaging and a second mode in which the apparatus does not perform imaging but stands by, insert the first filter into an optical path of the element in a case where a mode is shifted from the first mode to the second mode, and remove the first filter from the optical path in a case where the mode is shifted from the second mode to the first mode.
