Patent ID: 8027577

Claim:
A camera comprising: a central processing unit (CPU); an image memory; an information memory; a location sensor that detects a present location of the camera; a focal length detector that detects a present focal length of a photographic lens of the camera; a zoom adjuster; and a plurality of monitors; wherein at least one of the CPU, the image memory and the information memory records a past location, the past location being a location where an image was photographed at a previous point in time, at least one of the CPU, the image memory and the information memory records a past focal length of the photographic lens, the CPU compares the present location of the camera with the past location, the CPU calculating a camera location difference between the present location of the camera and the past location, the CPU compares the present focal length of the photographic lens with the past focal length of the photographic lens, the CPU calculating a focal length difference between the present focal length of the photographic lens and the past focal length of the photographic lens, the zoom adjuster adjusts the present focal length of the photographic lens so that the present focal length of the photographic lens coincides with the past focal length of the photographic lens, the photographic lens having a function for changing the focal length of the photographic lens, and at least one of the plurality of monitors displays at least one of the calculated camera location difference and the calculated focal length difference.
