THREE-DIMENSIONAL IMAGE SENSING DEVICE AND METHOD OF SENSING THREE-DIMENSIONAL IMAGES |
摘要 |
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. |

1. A three-dimensional image sensing device, comprising:
a light source for generating flashing light with a K multiple of a frequency of flicker noise or a predetermined frequency, wherein K is a positive real number, and the flicker noise is generated by an alternating current source; a sensing module, comprising:
a pixel array for sampling the flashing light to generate a sampling result, wherein the sampling result comprises a plurality of first images during turning-on of the light source and a plurality of second images during turning-off of the light source;a control unit for executing an image processing on the sampling result to generate a spectrum corresponding to the sampling result; anda light source driver for driving the light source according to the K multiple of the frequency or the predetermined frequency; and a signal processing module coupled to the sensing module for generating the K multiple of the frequency according to the spectrum, and generating depth information according to the plurality of first images and the plurality of second images, wherein when the K multiple of the frequency is within a predetermined frequency range, the signal processing module outputs the K multiple of the frequency to the light source driver, or when the K multiple of the frequency is outside the predetermined frequency range, the signal processing module outputs the predetermined frequency to the light source driver. |
