    Abstract: A light source device includes: a mounting board; a plurality of light-emitting parts disposed on the mounting board, each of the plurality of light-emitting parts being configured to be individually turned on; a light-shielding member defining an opening; and a light-guide member supported by the light-shielding member, the light-guide member comprising a Fresnel lens portion, wherein, in a top view, the Fresnel lens portion is located within an area of the opening of the light-shielding member. In the top view, irradiation areas of the respective light-emitting parts are at least partially separated from each other.

    Abstract: Light modification devices for photography, videography, or other image capturing systems which provide methods for diffusing and shaping light from flash lighting or continuous light sources to create a diffused 360 degree thin plane of light around a subject. The light modification devices are capable of producing lighting conditions that can accentuate raised textures and depth of a subject without casting hard shadows with minimal light seepage outside of the plane.

    Abstract: A light source module includes an illumination element and an adjustable light diffusing material. The light source module is configured to receive or generate a control signal for adjusting diffusion of light emitted from the light source module and accordingly adjust an amount of diffusion of light emitted from the light source module. In some embodiments, an adjustable light diffusing material includes a polymer stabilized cholesteric texture (PSCT), a smectic phase liquid crystal, a polymer network liquid crystal (PNLC), or other suitable material. A controller for a light source module may determine a level of diffusion based on a level of inclusion of a wide-angle field of view of a wide-angle lens system or a telephoto field of view of a telephoto lens system in a composite camera field of view that includes a combination of the wide angle field of view and the telephoto field of view. Also, the controller may determine a level of diffusion based or an estimated distance to a scene in a camera field of view that is to be captured.

    Abstract: The technology disclosed herein relates to an imaging device. In some embodiments the imaging device has a support plate defining an object plane. A housing surrounds the object plane across the support plate. A first reflector plane is within the housing and in reflective communication with the object plane. The first reflector plane is 68.0° to 70.0° from the object plane. A second reflector plane within the housing and in reflective communication with the object plane. The second reflector plane is 68.0° to 70.0° from the object plane. Other embodiments are also described.

    Abstract: An image pickup system, which includes an image pickup apparatus, a sender device and a receiver device each including a light emission part and controls light emission amounts thereof, and which achieves the best light emission performance at the time of manual light emission. In the image pickup system: the image pickup apparatus sets manual light emission amounts of the sender device and receiver device, and sets light emission activated setting or light emission deactivated setting on the sender device; the sender device changes a light emission amount settable range in which the manual light emission amount is settable, based on a setting set on the sender device, and notifies the receiver device of the set manual light emission amount; and the receiver device updates the manual light emission amount of the receiver device based on the notified manual light emission amount.
