The image pickup apparatus of the present invention sets at least an imaging magnification of an optical system included in a second image pickup device or a sampling pitch of a signal in the second image pickup device; calculates, using image data of a plurality of frames captured by second image pickup device during exposure of first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames; and controls the exposure of the first image pickup device for the image data of the first frame, on the basis of the calculated amount of subject motion.

In an ophthalmic imaging system an image imaged by an imaging section for a right eye is formed as an imaging image on a display, and then displayed through a right-eye optical unit and a reflection member. An image imaged by an imaging section for a left eye is formed as an imaging image on a display, and then displayed through an optical unit and the reflection member. This thereby enables the object to be visually inspected as a three-dimensional image by the observer viewing the right-eye imaging image and the left-eye imaging image, which differ from each other according to the parallax therebetween, by viewing the respective images through right and left eyes.

Provided are an imaging device and an image data generation method which are capable of reducing noise generated in an image in which crosstalk is removed. In an imaging device (1) that captures images corresponding to optical systems at one time by using an imaging lens (10) including a plurality of optical system of which imaging characteristics are different and an image sensor (100) including a plurality of light receiving sensors of which crosstalk ratios are different in each pixel, the number (m) of light receiving sensors included in each pixel of the image sensor (100) is larger than the number (n) of optical systems included in the imaging lens (10) (m>n). Accordingly, it is possible to reduce noise generated in an image in which crosstalk is removed.

The optical system having an imaging lens that images a first-plane and a second-plane which are discontinuous includes: a first-optical-system that images the first-plane; a second-optical-system that images the second-plane; and a common-optical-system that forms a subject image, which is incident through the first-optical-system, on the first-light-receiving-region of the image sensor and forms a subject image, which is incident through the second-optical-system, on the second-light-receiving-region of the image sensor. In the optical system, an angle of view, at which imaging is performed by the first-optical-system and the common-optical-system, overlaps with an angle of view, at which imaging is performed by the second-optical-system and the common-optical-system. The optical system includes a first focus adjustment unit that adjusts the focus of the optical system composed of the first-optical-system and the common-optical-system and a second focus adjustment unit that adjusts the focus of the optical system composed of the second-optical-system and the common-optical-system.

High image quality real-time distribution of omnidirectional images is enabled.

An imaging unit obtains a front image and a back image each having an ultra-wide viewing angle of greater than or equal to 180. A transmission unit transmits the front image and the back image each having the ultra-wide viewing angle to an external device. For example, the imaging unit includes: a first imager that captures a front-side image taken in by a fisheye lens to obtain a front image having an ultra-wide viewing angle; and a second imager that captures a back-side image taken in by a fisheye lens to obtain a back image having an ultra-wide viewing angle, in which the second imager is arranged in a state of being rotated by 90 with respect to the first imager, the first imager captures the front-side image taken in by the fisheye lens in a state where the upper end side and the lower end side of the front-side image are partially missing, and the second imager captures the back-side image taken in by the fisheye lens in a state where the left end side and the right end side of the back-side image are partially missing.

Provided are an imaging apparatus and a mobile imaging apparatus capable of reducing the size and weight of a structure relating to focus adjustment. The imaging apparatus 1 includes: a central optical system 12 that captures an image with pan focus; an annular optical system 14 that is disposed concentrically with the central optical system 12; and an image sensor 20 that simultaneously captures an image to be formed through the central optical system and an image to be formed through the annular optical system 14. In the imaging apparatus 1, the central optical system 12 and the image sensor 20 are moved integrally along the optical axis L so as to adjust a focal point of the annular optical system 14.
