A multispectral imaging device, comprising a pixel array, each said pixel comprises at least a first subpixel and a second subpixel, each subpixel comprises at least an infrared light conversion layer; a visible light conversion layer and a color filter layer; said visible light conversion layer is arranged between said infrared light conversion layer and said color filter layer; wherein, infrared conversion efficiency in said first subpixel is larger than infrared conversion efficiency in said second subpixel, and infrared light transmittance of the color filter layer in said first subpixel is larger than infrared light transmittance of the color filter layer in said second subpixel. The multispectral imaging device realizes imaging in multiple wavebands and in an increased dynamic range.
