Title:
PORTABLE POLARIZED DIGITAL CAMERA AND IMAGING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/004898
Kind Code:
A1
Abstract:
A portable polarized digital camera and an imaging method therefor. The portable polarized digital camera comprises: three polarizers (11) and an image sensor (12). The three polarizers (11) are stuck into a first area (1211), a second area (1212), and a third area (1213) of a pre-set wavelength channel (121) on one side of the image sensor (12) in parallel at a first pre-set angle, a second pre-set angle, and a third pre-set angle respectively. The pre-set wavelength channel (121) is divided into four areas. The polarizers (11) are used to shield and transmit incident light, so as to obtain light signals having different polarizing angles. The image sensor (12) is used to receive the light signals having different polarizing angles, which are obtained by the three polarizers (11), and convert the light signals having different polarizing angles into electric signals. By sticking a plurality of polarizers (11) into a pre-set wavelength channel (121), light reflection of a non-metal surface can be effectively weakened or eliminated, the color saturation is improved, the contrast is increased, a wider field-of-view image is acquired, and more exquisite imaging is realized.
