A method and an apparatus for adjusting photography parameters are provided. The method includes: determining a pupil size of a person; and adjusting one or more photography parameters according to the pupil size. The pupil size of the person is determined, and then one or more photography parameters such as the aperture size may be adjusted automatically according to the pupil size of the person. Since a current pupil size is subject to a light intensity in current surroundings, the photography parameters of a photographic device may be adjusted automatically and efficiently based on the pupil size.

Provided is a technology enabling an imaging apparatus and an interchangeable lens to appropriately perform initialization processes. An interchangeable lens includes one or more lens-side processors configured to perform initialization of a plurality of lens-side elements. The one or more lens-side processors is further configured to transmit lens-side initialization element information indicating the plurality of lens-side elements to an imaging apparatus. The technology can be applied to, for example, a camera system including a detachable interchangeable lens and an imaging apparatus serving as a camera body side.

An anti-dazzle imaging camera is provided that includes a photorefractive crystal that is wavelength-agnostic. The photorefractive crystal is configured to receive an optical beam. When the optical beam includes no laser, the photorefractive crystal is configured to pass the optical beam unchanged to an imaging detector. When the optical beam includes a laser, the photorefractive crystal is configured to attenuate the laser to generate a modified optical beam and to pass the modified optical beam to the imaging detector.

An image obtaining apparatus, for obtaining an image from an image sensor provided in a vehicle, is provided. The image obtaining apparatus includes: a processor, and a memory including at least one instruction executable by the processor. In response to the at least one instruction being executed by the processor, the processor is configured to: obtain an initial image from the image sensor, the initial image including an object; determine a type of the object included in the initial image; adjust a shutter speed of the image sensor based on the determined type of the object included in the initial image; and obtain a first image from the image sensor based on the adjusted shutter speed.

Included is an imaging unit that outputs images by imaging a subject, a light amount adjustment unit that drives a light amount adjustment member to adjust the amount of light input to the imaging unit, a control unit that controls the imaging unit so that after a first image is output by the imaging unit, a second image having an exposure amount different from that of the first image is output, and a setting unit that sets the difference in the exposure amount between the first image and the second image. The first image and the second image are images used for compositing. The setting unit sets the difference in the exposure amount between the first image and second image so that the relative relationship in the exposure amount between the first image and the second image imaged when the light amount adjustment unit is operating is the same as the relative relationship in the exposure amount between the first image and the second image imaged when the light amount adjustment unit is not operating.

A method of obtaining an image from an image sensor provided in a vehicle includes obtaining a vehicle speed of the vehicle; adjusting a shutter speed of the image sensor; adjusting either one or both of an international organization for standardization sensitivity (ISO) of the image sensor and an aperture of the image sensor based on the vehicle speed; and obtaining the image from the image sensor based on the adjusted shutter speed and the adjusted either one or both of the ISO and the aperture.

The present technology relates to an interchangeable lens and a method for controlling the same capable of starting shooting in consideration of mechanical fluctuations after a diaphragm is driven, a shooting apparatus, and a camera system. An interchangeable lens includes: a diaphragm; a diaphragm driving unit configured to drive the diaphragm; and a lens control unit configured to transmit diaphragm driving information including stabilization time information of the diaphragm to a shooting apparatus when the diaphragm driving unit drives the diaphragm. The present technology is applicable to lens-interchangeable digital cameras, and the like, for example.

Provided are a method and system for determining an optimal exposure of a structured light based 3D camera. The system includes a projecting means for illuminating a predetermined pattern on a target object, an image capturing means for capturing an image of the target object with the pattern projected, and a processing means for reconstructing 3D data for the target object by identifying the pattern of the captured images from the image capturing means. The system automatically determines an optimal exposure of the structured light based 3D camera system through analyzing the captured image of the target object.
