Abstract
The application discloses an imaging device and an imaging method. The imaging device includes: an imaging device, a spectroscopic device, a plurality of sensors, and an image processing device; the spectroscopic device is arranged on the exit surface of the imaging device, and is used to separate the light rays injected into the spectroscopic device by the imaging device into light emitted from a plurality of exit surfaces. light; a plurality of sensors are respectively arranged on a plurality of exit surfaces of the spectroscopic device for generating pre-processed images; the image processing device is connected with the plurality of sensors and is used for fusing the multiple pre-processed images to obtain an output image. The imaging device provided by this application can realize the fusion of imaging on multiple components to obtain an image with a wide dynamic range only by one exposure. Compared with the multiple exposure method in the prior art, on the one hand, it effectively solves the problem of The image fusion caused by the multiple exposure method has inherent defects such as ghosting and blurring, and avoids the problem of low light ability of the image after multiple exposure synthesis.
Description
technical field [0001] The invention relates to the field of image technology, in particular to an imaging device and an imaging method. Background technique [0002] Since the invention of camera technology, there has always been a problem that the dynamic range of illuminance (that is, the range of illuminance change in the shooting area) is too narrow. The outdoor light can reach thousands of Lux under the sunlight on a sunny day. Under such light environment, indoor and outdoor objects cannot be photographed clearly at the same time. For example, in this case, the outdoor light is dominant, and the exposure time of the camera will be relatively small, such as 1 / 4000s, the exposure time is just right for outdoor objects and the objects are clear, but the exposure time for indoor objects is insufficient, and the reflected phenomenon It's because the room is dark and you can't see objects. Existing ordinary cameras generally have a backlight compensation function. By incr...
