Claim 15:
16. A sensing device capable of detecting a distance to an object comprising:
one or more first sensing pixels configured to detect light and measure a distance to a target object based on a first distance measuring technique;
a first pixel driver coupled to and operable to control the one or more first sensing pixels in detecting light for measuring the distance;
one or more second sensing pixels configured to detect light and measure a distance to a target object based on a second distance measuring technique that is different from the first distance measuring technique so that the first and second distance measuring techniques have different distance measuring characteristics;
a second pixel driver coupled to and operable to control the one or more second sensing pixels in detecting light for measuring the distance; and
a controller configured to activate either the one or more first sensing pixels or the one or more second sensing pixels based on the different distance measuring characteristics of the first and second sensing pixels with respect to a distance between the target object and the sensing device,
wherein each of the one or more first sensing pixels corresponds to a direct pixel configured to sense the distance to the target object based on time information of light reflected from the target object,
wherein each of the one or more second sensing pixels corresponds to an indirect pixel configured to sense the distance to the target object based on phase information of light reflected from the target object,
wherein the first sensing pixel is included in:
a first direct pixel group in which a plurality of first sensing pixels is arranged in a line in a first direction; or
a second direct pixel group in which the plurality of first sensing pixels is arranged in a line in a second direction, and
wherein the first direct pixel group and the second direct pixel group cross each other.
