A three-dimensional image sensing device includes a light source, a sensing module, and a signal processing module. The sensing module includes a pixel array, a control unit, and a light source driver. The light source generates flashing light with a K multiple of a frequency of flicker noise or a predetermined frequency. The pixel array samples the flashing light to generate a sampling result. The control unit executes an image processing on the sampling result to generate a spectrum. The light source driver drives the light source according to the K multiple of the frequency or the predetermined frequency. The signal processing module generates the K multiple of the frequency according to the spectrum, or outputs the predetermined frequency to the light source driver, and generates depth information according to a plurality of first images/a plurality of second images during turning-on/turning-off of the light source included in the sampling result.
