High dynamic range imaging system and method

A high dynamic range imaging system includes a pixel array providing a high sensitivity signal and a low sensitivity signal; and a high dynamic range encoder for generating an encoded signal accordingto the high sensitivity signal and the low sensitivity signal. And when the high-sensitivity signal is not greater than the preset critical value, the flag bit is set to be active, otherwise, the flag bit is set to be non-active. 一种高动态范围成像系统包含像素阵列，提供高感光度信号与低感光度信号；及高动态范围编码器，根据高感光度信号与低感光度信号以产生编码信号。当高感光度信号未大于预设临界值时，则将旗标位设为主动，否则将旗标位设为非主动。
