An image-capturing system and method analyze the darkest and brightest pixels indicated by an electrical signal to adjust the transmittance of each pixel of an optical element, so as to enhance the dynamic range of an image and to exhibit the details in bright and dark portions of the image. The image-capturing system includes an optical element, defining a plurality of pixels of controllable transmittance for modulating a received image; at least one lens for focusing the modulated image; an image sensor for transforming the focused image into an electrical signal; a processing unit for outputting a control signal, in response to the electrical signal, to respectively control the transmittance of each pixel of the optical element; and a storage unit, coupled with the processing unit, for storing an image information.
