    • An image sensing system includes: a light emitting device; a pixel configured to capture an optical signal and to convert the optical signal into an analog image signal; an analog circuit configured to selectively filter the analog image signal; an analog-to-digital converting circuit configured to convert the analog image signal to a digital image signal; a digital circuit configured to receive the digital image signal and to switch the light emitting device on and off; wherein the digital image signal includes a dark image frame if the optical signal is captured when the light emitting device is off; wherein the digital image signal includes an effective image frame if the optical signal is captured when the light emitting device is on and the analog circuit is configured to filter the analog image signal; and wherein the digital image signal includes a punctured image frame if the optical signal is captured when the light emitting device is on and the analog circuit is not configured to filter the analog image signal.
    • 一种图像感测系统包括:发光装置; 被配置为捕获光信号并将所述光信号转换为模拟图像信号的像素; 模拟电路,被配置为选择性地滤波模拟图像信号; 模拟数字转换电路,被配置为将模拟图像信号转换为数字图像信号; 配置为接收数字图像信号并打开和关闭发光装置的数字电路; 其中如果在所述发光装置关闭时捕获所述光信号,则所述数字图像信号包括暗图像帧; 其中如果在发光器件接通时捕获光信号并且模拟电路被配置为对模拟图像信号进行滤波,则数字图像信号包括有效图像帧; 并且其中如果在所述发光装置接通时捕获所述光信号且所述模拟电路未被配置为过滤所述模拟图像信号,则所述数字图像信号包括穿孔图像帧。
