Abstract

Disclosed is a flexible filter spectral camera. A flexible filter module includes N flexible filter units corresponding to N different wavebands, respectively, where N is a positive integer greater than or equal to 2. A CMOS (Complementary Metal Oxide Semiconductor) module is used to convert incident light into a digital signal. Any one of the N flexible filter units can be switched to a preset position to filter light emitted from a lens and transmit light at a corresponding waveband to the CMOS module. The preset position is between the lens and the CMOS module. An image processor is connected to the CMOS module and is used to convert the digital signal into an image. In accordance with the present disclosure, precision imaging of the lens is achieved, the overlapping accuracy and imaging quality of the images are improved, and meanwhile, the processing efficiency for overlapped images is improved.
