The invention provides an earth-stationary-orbit large-area-array-camera large-dynamic imaging system, which can solve the problem with large-area-array-camera large-dynamic imaging through integral time's continuous adjustment. The imaging system comprises an optical system, a visible large-area-array large-dynamic imaging module, a visible integral time adjusting module, an infrared large-area large-dynamic imaging module, and an infrared integral time modulation module. The optical system gathers the ground object information to the visible light/infrared large-area large-dynamic imaging module and the visible light/infrared large-area large-dynamic imaging module performs large-dynamic imaging on the ground object information. The integral time of the visible light/infrared integral time adjusting module to the visible light/infrared large-area large-dynamic imaging module can be adjusted according to requirement.
