Abstract
A lens unit 1 acquires identification information for an attached lens unit from the lens unit and stores the acquired identification information in a second memory 37. In a case in which correction information for the stored identification information is not registered, a CPU 36 reads the correction information for the stored identification information out from an external memory 39 and registers it.
Claims8
An apparatus including a correction unit that corrects a sensed image based on correction information for a lens unit registered in advance in a correction information storage unit, the apparatus comprising:
- an acquisition unit that acquires identification information for a lens unit and, if the acquired identification information is different from identification information which has been acquired previously, registers in the correction information storage unit the acquired identification information and a flag indicating that correction information for the acquired identification information is not registered in the correction information storage unit;
- a connection unit that connects to an external device storing multiple pieces of correction information for different lens units by identification information;
- and
- a control unit that, in a case where the external device is connected to the apparatus and the flag exists, reads out correction information for the identification information corresponding to the flag from the external device, registers the read-out correction information in the correction information storage unit, and changes the flag to a flag indicating that the correction information has been registered in the correction information storage unit.
A control method for an apparatus including a correction unit that corrects a sensed image based on correction information for a lens unit registered in advance in a correction information storage unit and a connection unit that connects to an external device storing multiple pieces of correction information for different lens units by identification information,
- the control method comprising:
- an acquisition step of acquiring identification information for a lens unit and, if the acquired identification information is different from identification information which has been acquired previously, registering in the correction information storage unit the acquired identification information and a flag indicating that correction information for the acquired identification information is not registered in the correction information storage unit;
- and
- a control step of, in a case where the external device is connected to the apparatus and the flag exists, reading out correction information for the identification information corresponding to the flag from the external device, registering the read-out correction information in the correction information storage unit, and changing the flag to a flag indicating that the correction information has been registered in the correction information storage unit.
