Abstract: There is provided an image capturing apparatus that captures a plurality of images, calculates a three-dimensional position from the plurality of images, and outputs the plurality of images and information about the three-dimensional position. The image capturing apparatus includes an image capturing unit, a camera parameter storage unit, a position calculation unit, a position selection unit, and an image complementing unit. The image capturing unit outputs the plurality of images using at least three cameras. The camera parameter storage unit stores in advance camera parameters including occlusion information. The position calculation unit calculates three dimensional positions of a plurality of points. The position selection unit selects a piece of position information relating to a subject area that does not have an occlusion, and outputs selected position information. The image complementing unit generates a complementary image, and outputs the complementary image and the selected position information.

Abstract: An imaging apparatus in an embodiment includes lens optical systems each including a lens whose surface closest to the target object is shaped to be convex toward the target object, imaging regions which respectively face the lens optical systems and output a photoelectrically converted signal corresponding to an amount of light transmitting the lens optical systems and received by the imaging regions, and a light-transmissive cover which covers an exposed portion of the lens of each of the lens optical systems and a portion between the lens of one of the lens optical systems and the lens of another one of the lens optical systems adjacent to the one of the lens optical systems, the cover having a curved portion which is convex toward the target object. The optical axes of the lens optical systems are parallel to each other.

Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.
