Abstract
According to an embodiment, an imaging system includes an image sensor, an imaging lens, a microlens array, an irradiator, a distance information acquiring unit, and a controller. The microlens array includes multiple microlenses arranged with a predetermined pitch, the microlenses being respectively associated with pixel blocks. The irradiator emits light to project a pattern onto an object. The distance information acquiring unit acquires information on the distance in the depth direction to the object on the basis of a signal resulting from photoelectric conversion performed by the image sensor. The controller controls the irradiator so that images contained in a pattern that is reflected by the object and scaled down on the image sensor by the imaging lens and the microlenses are smaller than the arrangement pitch of images each formed on the image sensor by each microlens and larger than twice the pixel.
