Claim 11:
12. The terminal device according to claim 10, wherein the depth camera comprises:
an emitting module configured to emit the speckle array to an object; and
a receiving module comprising an image sensor, the image sensor comprising a sensor array, the sensor array comprising m*n pixel units, wherein each of the pixel units comprises a CMOS photodiode and a photoelectric signal reading circuit, the photodiode is configured to receive the speckle array reflected by the object, and generate a corresponding photocurrent signal based on the speckle array, a current intensity indicated by the photocurrent signal is positively correlated with a light intensity of light beam irradiation received by the photodiode, and the photoelectric signal reading circuit is configured to read the photocurrent signal and output a corresponding pixel signal.
