Abstract: The present invention provides a depth image generation apparatus comprising: a light source for generating light to be emitted toward an object in order to solve an SNR problem caused by resolution degradation and an insufficient amount of received light, while not increasing the amount of emitted light when photographing a remote object; a first optical system for emitting, as a dot pattern and at the object, the light generated by the light source; an image sensor receiving the light reflected by the object, so as to convert the received light into an electrical signal; an image processor for acquiring depth data through the electrical signal; and a control unit connected to the light source, the first optical system, the image sensor and the image processor, wherein the control unit controls the first optical system so as to scan the object by moving the dot pattern in a preset pattern.

Abstract: The present invention can provide a depth image generation apparatus comprising: a light source for generating light to be emitted toward an object in order to solve an SNR problem caused by resolution degradation and an insufficient amount of received light, while not increasing a light-emitting amount when photographing a remote object; a first optical system for emitting, as a dot pattern, at the object, the light generated by the light source; an image sensor for receiving light reflected from the object and converting same into an electrical signal; an image processor for acquiring depth data through the electrical signal; and a control unit connected to the light source, the first optical system, the image sensor and the image processor, wherein the control unit controls the first optical system so as to scan the object by moving the dot pattern in a preset pattern.
