Abstract
An imaging apparatus according to the present invention can generate an image from an output of an image sensor to record the image as an image file, and record first information and second information onto the image file as additional information. Accordingly, the imaging apparatus can provide a user or a staff person of a repair center with useful information regarding a failure, repair, and replacement that conventionally could not be provided.
Claims17
An imaging apparatus comprising:
- an image sensor configured to capture an image of an object;
- an acquisition unit configured to acquire first information as device identification information of a mounted lens unit, and second information of the lens unit which is added along with driving of the lens unit,
- wherein the second information includes endurance information corresponding to a number of driving times;
- and
- a recording unit configured to generate an image from an output of the image sensor to record the image as an image file, and record the first information and the second information onto the image file as additional information.
A lens unit which can be mounted on a camera unit, the lens unit comprising:
- a diaphragm driving unit capable of controlling a diaphragm based on an instruction from the camera unit;
- a memory configured to store first information as device identification information and second information of the lens unit which is added along with driving of the lens unit,
- wherein the second information includes endurance information corresponding to a number of driving times;
- and
- a mount which can communicate the first information and the second information to the camera unit.
A method for controlling an imaging apparatus including an image sensor configured to capture an image of an object, and an acquisition unit configured to acquire first information as device identification information of a mounted lens unit, and second information of the lens unit which is added along with driving of the lens unit, wherein the second information includes endurance information corresponding to a number of driving times, the method comprising:
- generating an image from an output of the image sensor to record the image as an image file, and recording the first information and the second information onto the image file as additional information.
A method for controlling a lens unit which can be mounted to a camera unit and includes first information as device identification information, the method comprising:
- controlling a diaphragm based on an instruction from the camera unit;
- and
- recording second information of the lens unit which is added along with driving of the lens unit, wherein the second information includes endurance information corresponding to a number of driving times and communicating the first information and the second information to the camera unit.
