Abstract
The utility model discloses a graphic sensing device applicable in a multi-light environment, which comprises a spectral filter at one side and several auxiliary lamps and sensors at the other side. The several auxiliary lamps are located around the sensors and consist of narrow-wave lights, which can be set into one or two spectrums. The spectral filter is provided with an angle and can be set into a spectrum, which is the same as the spectrum set by the auxiliary lamps. The utility model provides a graphic sensing device applicable in a multi-light environment. The device can locate an object to be shot exactly and get various required light wave bands in the multi-light environment, so the imaging quality of the graphic sensing device would be greatly improved.
Description
Technical field
The utility model relates to a kind of image sensing device, relates in particular to a kind of image sensing device that is adapted to multiple light environment.
Technical background
More existing image sensing devices are for example made a video recording and first-classly substantially all are made up of three big parts, are followed successively by: optical filter, auxiliary lamp and sensor.The light of auxiliary lamp emission sees through optical filter and shines the subject back reflection, and the light that reflects mating plate after filtration arrives sensor, and imaging on sensor.This camera has following deficiency: multiple light is incident to optical filter from different angles, and wherein the very inclined to one side incident ray of angle can cause the decline of image quality; Under some particular surroundings (for example dark place or snowfield etc.), the light that needs certain wave band just can better imaging, if these light are not compensated, just causes image quality not good easily.
For example in face recognition technology, at first by camera picked-up facial image, handle in processor inside by face recognition algorithms then, though current face recognition algorithms accuracy rate progressively improves, but can not adapt to the facial image of gathering under the various light, in the face of some at light facial image relatively poor or that comparatively gather under the complex environment, the image quality of the facial image of collection is more not good.
