摘要:
The invention relates to a method and a device for creating pictures and more particularly a method for creating an enhanced picture by means of several consecutive exposures. The exposures are combined to create pictures with enhanced properties, especially better color and light content. Sufficient light is obtained by performing a series of first exposures together with one second exposure in rapid succession. The first exposures are combined to provide sufficient luminance and sharpness. The second exposure is made to collect color information. The first exposures are combined with the second exposure to provide an enhanced picture.
