Title:
All the celestial sphere type a pickup system and an image pick-up optical system
Document Type and Number:
Japanese Patent JP6019970
Kind Code:
B2
Abstract:
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 4π 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.
