1. An image sensing device comprising:
a pixel array configured to include at least one first pixel and at least one second pixel; and
a timing controller configured to activate either a first pixel or a second pixel based on a distance between a target object and the pixel array,
wherein:
the first pixel and the second pixel have different characteristics that include at least one of an effective measurement distance related to an ability to effectively sense a distance, a temporal resolution related to an ability to discern a temporal difference, a spatial resolution related to an ability to discern a spatial difference, or unit power consumption indicating an amount of power required to generate a pixel signal;
the first pixel 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;
the second pixel corresponds to an indirect pixel configured to sense the distance to the target object based on phase information of the light reflected from the target object; and
the first pixel is included in:
a first direct pixel group in which a plurality of first pixels is arranged in a line in a first diagonal direction; or
a second direct pixel group in which the plurality of first pixels is arranged in a line in a second diagonal direction.
