Abstract:
1. An imaging unit comprising: a first light source adapted to illuminate a first object with first light; a first sensor, including a first light receiving element adapted to detect the first light by way of the first object; a second sensor, including a second light receiving element adapted to detect a second light which is externally inputted by way of a second object; a first lens; a second lens; and a transparent member, disposed on an optical path extending from the second object to the second sensor through the second lens, wherein a first conjugate length of the first lens is equal to a second conjugate length of the second lens, the first light receiving element is adapted to detect the first light reflected by the first object and the second light receiving element is adapted to detect the second light passing through the second object, the second light receiving element includes a plurality of kinds of third light receiving elements provided color filters differing in color from one another a first resolution of the first sensor is less than a second resolution of the second sensor, and the third light receiving elements extend in a main scanning direction and are arranged in a sub scanning direction.
