Imaging device with multiple light sources for spectral imaging
The patent application (Publication Number: US20240027340A1) describes an imaging device that includes a camera with an image sensor having spectral optical filters of N bands, sensitivity to visible light and near-infrared range, M types of light sources with emission spectral characteristics in different wavelength ranges, an optical filter to transmit light beams from the light sources, and a conversion unit to generate image signals of M bands. The device captures images by applying light to different areas of the subject and selecting the direction and intensity of light for each area. The camera can be a general-purpose color camera with an infrared light cut-off filter removed, and the light sources can include visible light and near-infrared sources.
Furthermore, the patent application details an inspection device incorporating the imaging device for inspecting subjects based on the generated image signals. The inspection processing unit can be used to inspect characters on containers containing liquid, including areas with optical transparency. The method outlined in the patent involves applying light from multiple sources to the subject, photographing different areas, and generating image signals with spectral sensitivity to the applied wavelengths. The method allows for individual illumination of target areas and selection of light direction and intensity for each area, determining whether the captured image is formed by transmitted or reflected light. The patent application aims to improve imaging and inspection processes by utilizing multiple light sources and spectral filters to enhance image quality and accuracy in various applications.
