Abstract
In a method of operating a three-dimensional image sensor according to example embodiments, modulated light is emitted to an object of interest, the modulated light that is reflected from the object of interest is detected using a plurality of depth pixels, and a plurality of pixel group outputs respectively corresponding to a plurality of pixel groups are generated based on the detected modulated light by grouping the plurality of depth pixels into the plurality of pixel groups including a first pixel group and a second pixel group that have different sizes from each other.

A method of operating a three-dimensional image sensor, the method comprising:
- emitting modulated light to an object of interest;
- detecting, at a plurality of depth pixels in the three-dimensional image sensor, reflected modulated light that is reflected from the object of interest;
- and
- generating a plurality of pixel group outputs respectively corresponding to a plurality of pixel groups based on the detected modulated light by grouping the plurality of depth pixels into the plurality of pixel groups including a first pixel group and a second pixel group.
A method of operating a three-dimensional image sensor including a light source module and a plurality of depth pixels, the light source module including a light source and a lens, the method comprising:
- emitting first modulated light to an object of interest using the light source module;
- detecting the first modulated light that is reflected from the object of interest using the plurality of depth pixels;
- obtaining position information of the object of interest based on the detected first modulated light;
- adjusting a relative position of the light source to the lens based on the position information;
- emitting second modulated light to the object of interest using the light source module in which the relative position of the light source is adjusted;
- detecting the second modulated light that is reflected from the object of interest using the plurality of depth pixels;
- and
- generating a plurality of pixel group outputs respectively corresponding to a plurality of pixel groups based on the detected second modulated light by grouping the plurality of depth pixels into the plurality of pixel groups including a first pixel group and a second pixel group that have different sizes from each other.
