Systems and methods using the same to achieve a camera having precise timing of a camera shutter, which can be used also for a controllable aperture, are disclosed. The aperture can be controlled continuously and can therefore be used for video cameras. The shutter system is controlled by a feedback loop. The shutter blades are moved by at least one linear motor, a position sensor senses the actual position and speed of the blades. The movement of the blades can be stopped any time to get an aperture desired. For capturing an image in a first step a global reset is opening (activating) every pixel of the image sensor after the shutter is opened. In order to achieve a short active light exposure time (below 1 ms), after the global reset, the mechanical shutter invented closes rapidly after a defined active light exposure time. An active light exposure time is the time span between the image sensor is activated and the mechanical shutter is closed. In order to achieve a precise timing the shutter of the present invention uses electronic control and a feedback loop to control the actual position of the shutter.
