Image input device

An image input device comprising:

• an image source which generates an image light;
• a light sensor facing said image source, said light sensor including a two-dimensional array of photoelectric converting elements for generating electrical signals in response to the image light;
• a mask placed between said light sensor and said image source and having a two-dimensional array of apertures, the number of apertures corresponding to the number of said photoelectric converting elements;
• light deflector means placed between said mask and said image source for selectively deflecting the image light through said apertures of said mask to said light sensor, said light deflector means varying the amount of deflection of the image light in a predetermined timed order to divide the image light passing through said apertures into a plurality of components;
• and
• reading means connected to said light sensor for reading out electrical signals from said light sensor in the predetermined timed order.
