Abstract
The present disclosure discloses a three-dimensional (3D) image sensor and a related 3D image sensing module and hand-held device. The 3D image sensor includes, a photosensitive pixel array, including: a first photosensitive pixel; a second photosensitive pixel; and a pixel control signal transmission line, so that the first photosensitive pixel and the second photosensitive pixel respectively output a first photosensitive value and a second photosensitive value according to a pixel control signal; wherein the pixel control signal reaches a first node at a first time point and reaches a second node at a second time point; a delay detection module, including: a first delay detection circuit, for determining a time difference between the first time point and the second time point; and a processing unit, for generating the first depth information and the second depth information based on the first photosensitive value, the second photosensitive value, and the time difference.
