Method and device for outputting light

A light outputting device comprising:

• a light source configured to output a light to an object;
• a receiver configured to receive a light being reflected from the object;
• a memory configured to store an information on a reference area of the object recognized according to a distance between the light source and the object;
• and
• a processor configured to control an output of the light source by comparing a recognition area of the object recognized by the receiver with the reference area.

A light outputting device comprising:

• a light source configured to output a light to an object;
• a receiver including a plurality of pixels receiving a light being reflected from the object;
• and
• a processor configured to control an output of the light source when a light having an intensity higher than a preset intensity is detected in at least one of the plurality of pixels.

A light outputting device comprising:

• a light source configured to output a light to an object;
• a receiver including a plurality of pixels receiving a light being reflected from the object;
• and
• a processor configured to control an output of the light source by comparing a sum of light detection intensity values of each of the pixels recognizing the object among the plurality of pixels with a preset reference intensity value.

A method for controlling a light outputting device, the method comprising:

• outputting a light to an object;
• receiving a light being reflected from the object;
• storing an information on a reference area of the object recognized according to a distance from which the light is reflected from the object and received;
• and
• comparing a recognition area of the object recognized by the light being received and the reference area, and lowering or blocking an output of the light when the recognition area is less than or equal to a preset value than the reference area.
