Problems solved by technology

However, since this method is to process the image after the digital image is generated, the ability to restore details is very limited. As a result, the quality of the image captured by the camera device is not high in an environment with relatively high light contrast.

Abstract

An imaging device is disclosed, and comprises an image sensor and an electronic black card. The image sensor comprises a sensitization surface provided with a plurality of sensitization units and a microprocessor. The microprocessor comprises a brightness analysis module and a judgment module. The brightness analysis module carries out analysis on the environment brightness to obtain an optimal exposure time. The judgment module judges whether the image has an over-exposed area. The electronic black card is located on one side of the sensitization surfaces of image sensor, and comprises a plurality of switch units corresponding to the sensitization units, and a control unit. The control unit is used for calculating opening time of each switch unit, and controlling the opening and closing of each switch unit according to the opening time of each switch unit. The imaging device of the invention controls sensitization time of each sensitization unit by opening and closing each switch unitof the electronic black card, so as to avoid over-exposure of the image before the image is generated. In addition, an imaging method is also provided.

Description

technical field [0001] The invention relates to an imaging device and an imaging method thereof. Background technique [0002] When people use camera devices (such as digital cameras, mobile phones, etc.) to take pictures, in an environment with relatively large light contrast (that is, the brightness of the brightest part and the darkest part is very different), the image will usually be overexposed. In this case, the brightly lit areas of the image appear white, without details of color and brightness. [0003] This is mainly due to the fact that the generation of digital images is accomplished by using image sensors for photoelectric induction. The image sensor includes many photosensitive units and a microprocessor, and each photosensitive unit corresponds to a pixel. When shooting, the microprocessor will analyze the current ambient brightness to calculate the opening time of the shutter, that is, the exposure time of the image sensor. When the opening time of the sh...
