An imaging system includes an imaging body having an optical system and an imaging element, a power supplier configured to supply power to the imaging element, and a housing configured to hold the imaging body and the power supplier, wherein the optical system includes at least one optical element projecting from the housing, and a distance AP between a gravity center A of a portion including the optical system and a gravity center P of the entire imaging system and a distance BP between a gravity center B of the power supplier and the gravity center P of the entire imaging system satisfy the following condition.

Imaging system

An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4&#x3c0; radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.

Image capture system and imaging optical system

An imaging device includes two imaging optical systems each of the imaging optical systems including a wide-angle lens having an angle of view wider than 180 degrees, and an imaging sensor configured to image an image by the wide-angle lens, so as to obtain an image in a solid angle of 4&#x3c0; radian by synthesizing the images by the respective imaging optical systems, wherein the wide-angle lens of each of the imaging optical systems includes, in order from an object side to an image side, a front group having a negative power, a reflection surface and a back group having a positive power, and is configured to bend an optical axis of the front group by the reflection surface at 90 degrees toward the back group.

A communication terminal displays thumbnails for predetermined-region images in a panoramic image and accepts a selection of a predetermined thumbnail so as to display the predetermined-region image corresponding to the accepted thumbnail. This brings about an effect that a user can easily find a desired panoramic image or a desired predetermined-region image in the panoramic image.
