Abstract
The present invention provides an asymmetric optical sensor device comprising: a light emitting unit for outputting light; a light receiving unit which receives the light reflected by an external object, and consists of a plurality of pixels which correspond to regions of different angles with respect to the light emitting unit and are arranged in a row; and a lens unit for diffusing the light from the light emitting unit. The light amounts received by the plurality of pixels are light amount values which are asymmetric with respect to the center of the light receiving unit.
