摘要： The present disclosure pertains to a support device designed to enhance the quality of close-up photography. The device features a hollow body with one or more side walls that extend between a top portion and a base portion, defining an interior space. The top portion of the device is equipped with a structure configured to securely hold an image capture device, such as a smartphone or camera, in a fixed orientation. This orientation aligns the camera lens of the image capture device with a first viewing opening at the top portion, directing it towards a second viewing opening at the base portion. The second viewing opening is surrounded by a bottom edge of the base portion and is positioned at a predetermined distance from the first viewing opening, establishing a fixed field of view for the image capture device.

摘要： The imaging apparatus includes a stop, an APD filter, a ND filter, an imaging element, a main control section, a photometric section, a program diagram storage section, and an imaging exposure determination section. The ND filter can be inserted into or removed from the optical path. The photometric section calculates a photometric value from an imaging signal which is obtained by the imaging element. The program diagram storage section stores a program diagram in which an aperture value is fixed at an open aperture value at a specific amount of exposure or less. The imaging exposure determination section determines imaging exposure on the basis of an amount of imaging exposure which is calculated from photometric value and the program diagram. The main control section inserts the ND filter in the optical path in a case where the amount of imaging exposure is greater than the specific amount of exposure.

摘要： An image processing unit generates image data of an image based on an output signal from an imaging device, corrects the image data, and outputs corrected image data. An optical filter is structured such that an upper limit of a transmitting wavelength decreases as a distance from an optical axis of the imaging optical system increases on an imaging plane of the imaging device so that a light in an infrared region is transmitted on the optical axis and cut off at a position farthest away from the optical axis on the imaging plane. The image processing unit corrects the image data based on a correction equation corresponding to the upper limit of the transmitting wavelength.

摘要： An optical apparatus includes a stop having an aperture, two filter members each including a first area that includes a transmissive part and a gradation part having a transmittance that is lower than the transmittance of the transmissive part and that is changed in a moving direction of the filter member, an actuator that drives the two filter members, and a controller that controls the actuator. The two filter members are disposed so that both changing directions of densities of the gradation part and moving directions are opposite and the first area has a size capable of covering a whole of a first aperture. The controller controls the actuator so as to always move in an area between a first position and a second position. The transmissive part has a size that is incapable of covering the whole of the first aperture.

摘要： An adjustable photographic device includes a light transmission element for allowing light from an object to be photographed to pass therethrough, and light sources positioned around the periphery of the light transmission element for introducing light into the periphery of the light transmission element. This light introduced into the periphery of the light transmission element is internally reflected in the light transmission element causing the contrast of the photographed image to be controlled or modified without effecting the resolution thereof.
