Disclosed in the present invention is a camera module comprising: an optical output unit for outputting a first optical signal and a second optical signal to an object; a sensor for receiving a first reflected optical signal in which the first optical signal is reflected by the object; and a control unit for obtaining first distance information to the object by using the first optical signal and the first reflected optical signal, wherein an output of the first optical signal is smaller than an output of the second optical signal, and the control unit determines whether to output the second optical signal by using the first distance information.

Camera module outputting different optical signals based on depth of object

Disclosed are a ToF module and an object recognition device using the ToF module. The ToF module according to the present invention is a time of flight (ToF) module for measuring distance and depth information in a ToF manner, and comprises: a light transmitting unit for outputting light to an object; and a light receiving unit for receiving light reflected from the object, wherein the light transmitting unit comprises: a light source including a package of a plurality emitters; an emitter driving unit for selectively driving at least one emitter of the plurality of emitters; and a drive control unit for primarily controlling the driving of the plurality of emitters and, in accordance with the reflected light received by the light receiving unit, secondarily selecting at least one emitter of the plurality of emitters and controlling the driving thereof.

ToF module and object recognition device using ToF module

A light emitting device package includes: a light emitting device disposed on a substrate; a diffusion plate disposed on the substrate to surround the light emitting device; and a molding portion that is disposed on the substrate and has a shape of an aspheric lens whose center is recessed, The center of the molding portion is located on the same axis as the center of the light emitting device, and the diffusion plate may be interposed between the light emitting device and the molding portion. The molding portion having the shape of the aspheric lens whose center is recessed and the diffusion plate are employed to widely diffuse the light emitted from the light emitting device. Thereby, the efficiency of light can be increased, and manufacturing time and cost can be reduced. Simultaneously, a yellow ring phenomenon can be avoided.

Light emitting device package and lighting apparatus including the same

Embodiments provide a lighting apparatus including a light source unit including a first light source and a second light source, a light source driving unit including a first driver configured to supply first supply current to the first light source and a second driver configured to supply second supply current to the second light source, and a controller configured to control the first driver so as to vary the level of the first supply current and to control the second driver so as to fix the level of the second supply current.
