Description

Technical Field

Background

An optical imaging device such as a camera converts captured optical signals into electrical signals by a photoelectric conversion principle, stores the electrical signals in an image data mode, and can display the electrical signals on a display screen. The camera comprises a lens, a shutter, a photoelectric sensor and an image processor, wherein an object positioned in front of the lens is imaged on a photosensitive surface of the photoelectric sensor through the lens, a photoelectric conversion layer is used for carrying out electric signals, and the image processor is used for carrying out image processing to obtain image data. The shutter controls light to enter the lens and the sensor for imaging, and imaging can be controlled through time and speed.

When a camera performs capture imaging, the lens of the camera is generally directed toward a subject, and image capture is performed by shutter control after adjusting various parameters such as sensitivity and exposure time. Due to the limitation of the photosensitive size of the sensor, it is difficult to form a high-definition picture when the ambient light is insufficient, and a light compensation lamp, a flash lamp, or the like is usually used for light compensation at present.

However, in some special scenes, for example, when the surface, texture, and local microscopic morphology of the object such as a plant, a medicinal material, etc. need to be characterized, the compensation of the traditional flash lamp or the light supplement lamp toward a single direction is insufficient, and it is difficult to realize effective light compensation and high-definition imaging.
