Claim 8:
9. An electronic device, comprising: a light-emitting unit, configured to emit a light signal to a target to generate a reflected light signal; and
a depth-sensing device, comprising:
an image sensor, comprising a pixel array, configured to sense the reflected light signal reflected from the target to the pixel array, wherein the reflected light signal forms a plurality of light speckles on the pixel array, and the pixel array comprises a plurality of first-type pixels and a plurality of second-type pixels, wherein the first-type pixels are distributed in a first set of pixel rows of the pixel array, the second-type pixels are distributed in a second set of pixel rows of the pixel array, the first set of pixel rows do not overlap with the second set of pixel rows, and the pixel rows extend toward a first predetermined direction;
a depth information calculation unit, configured to obtain a time-of-flight (TOF) of the reflected light signal based on a plurality of sensing results of the plurality of first-type pixels, and obtain depth information of the target according to the TOF, and wherein the second-type pixels are not used to calculate the depth information; and
a storage, configured to store position information of the plurality of first-type pixels;
wherein the plurality of light speckles have a plurality of light speckle rows extending along the first predetermined direction, the plurality of light speckle rows are equally spaced, and the plurality of light speckles in each of the light speckle rows are pseudo-randomly spaced.
