摘要： An image sensor includes a sensor matrix including a plurality of sensing elements and a plurality of shutter control lines. Each sensing element includes an electronic shutter and a photo-detector, wherein the electronic shutter controls the exposure time of the photo-detector. Each shutter control line couples to a row or column of the electronic shutters, whereby different rows or columns of the electronic shutters can be independently controlled, and the photo-detectors in the same row or column can have the same exposure time.

摘要： There is provided an image system including at least one image sensor, a light source and a processing unit. The at least one image sensor sequentially acquires at least two images within each of the brightness variation intervals of an ambient light source. The light source lights once within each of the brightness variation intervals and the lighting of the light source is synchronized to one of the images acquired by the at least one image sensor. The processing unit calculates an image difference between the image synchronizing to the lighting of the light source and the image not synchronizing to the lighting of the light source thereby eliminating interference from the ambient light source. There is further provided a denoising method for an image system.
摘要翻译：提供了一种包括至少一个图像传感器，光源和处理单元的图像系统。所述至少一个图像传感器在环境光源的每个亮度变化间隔内顺序获取至少两个图像。光源在每个亮度变化间隔内亮起一次，并且光源的点亮与由至少一个图像传感器获取的图像之一同步。处理单元计算与光源的点亮同步的图像与不与光源的点亮同步的图像之间的图像差，从而消除来自环境光源的干扰。还提供了一种用于图像系统的去噪方法。

摘要： There is provided an interference removing method of an image system including the steps of: respectively acquiring different numbers of images within two brightness intervals having different brightness variations using an image sensor having a sampling frequency; lighting a light source with a lighting frequency, which is a half of the sampling frequency, and synchronizing to the sampling frequency; and subtracting a first image, which is associated with the lighting of the light source, acquired in a later brightness interval of two adjacent brightness intervals having identical brightness variations by a second image, which is associated with a sampling time of the first image, acquired in an earlier brightness interval of the two adjacent brightness intervals. The present disclosure further provides an image system.
