Claim 16:
17. A method for obtaining depth information comprising the steps of:
outputting light to an object through light sources on a first output line and light sources on a second output line;
receiving light reflected from the object through pixels on a first reception line and pixels on a second reception line; and
obtaining depth information on the object by using a phase difference between the outputted light and the received light,
wherein the phase difference between the light outputted from the light sources on the first output line and the light outputted from the light sources on the second output line is a first value,
wherein the phase difference between the time point when the light is received at the pixels on the first reception line and the time point when the light is received at the pixels on the second reception line is a second value, and
wherein the first value and the second value are different values.
