Camera apparatus

A camera apparatus comprising:

• an optical output unit configured to generate and emit an output light signal to an object;
• an optical input unit configured to receive an input light signal input after being reflected from the object;
• and
• a depth map generation unit configured to generate a depth map of the object using the input light signal input to the optical input unit,
• wherein the optical output unit includes:
• a light source configured to generate the output light signal;
• and
• a beam splitter configured to split the output light signal generated by the light source into a first polarization component and a second polarization component that differ from each other, and
• the first polarization component and the second polarization component are emitted to be distinguished from each other on the object,
• the first polarization component is emitted on the object in the form of a first spot array, and
• the second polarization component is emitted on the object in the form of a second spot array.
