Imaging device and imaging control method that detects and displays composition information
An imaging device including an image pickup device which converts an optical image of a photographic subject received through an imaging lens into an image signal; a displaying device which displays a through-the-lens image based on the image signal; a person detecting device which detects one or more persons from the image signal; a distance calculating device which calculates a distance between a plurality of the detected persons; and a composition assisting device which displays on the displaying device information as to whether the distance between the detected persons is proper or not based on the calculated distance between the detected persons.

6. The imaging device according to claim 5 , further comprising:
a storing device which stores a second predetermined distance being larger than the first predetermined distance; and
a device which enables the composition assisting device in a case when the distance between the detected persons is shorter than or equal to the stored second predetermined distance and disables the composition assisting device in a case when the distance between the detected persons is longer than the stored second predetermined distance.
7. The imaging device according to claim 6 , further comprising:
an input device which allows a user to set a shooting mode, wherein
the input device can be set to one of the shooting modes including a shooting mode that enables the composition assisting device and a shooting mode that disables the composition assisting device.
