Wide angle camera
View Patent ↗A wide-angle camera comprises a spectroscopic module, a first imaging module, and a second imaging module. The spectroscopic module comprises a spectroscopic lens holder, a first optical prism, and a second optical prism. The first optical prism is disposed on a first sidewall of the spectroscopic lens holder. The second optical prism is disposed on a second sidewall of the spectroscopic lens holder. The first sidewall is opposite to the second sidewall. An external light is split into a first light and a second light correspondingly through the first optical prism and the second optical prism. The first imaging module corresponds to the first optical prism and receives the first light for generating a first image. The second imaging module corresponds to the second optical prism and receives the second light for generating a second image. The first image and the second image are synthesized into a wide-angle image.
