Patent ID: 7903963

Claim:
An image capturing apparatus whose lens unit can be attached to and detached from a camera body section, comprising: an image-capturing signal processing section that generates an image signal by performing an image capturing process of subject light introduced via the lens unit; an attachment detecting section that generates a detection signal indicating whether or not the lens unit is attached to the camera body section; and a control section that determines, after detection of a recording start operation, whether or not the lens unit has been interchanged or detached and attached by using the detection signal, and performs a process of forming index data with respect to the image signal on the basis of a result of the determination, wherein the control section determines whether the lens unit has been interchanged or detached and attached by using the detection signal and identification information of the lens unit that is being attached, and upon determining that the lens unit has been interchanged the control section stores the identification information in the image capturing apparatus.
