An image sensor is a device that converts an optical image into an electronic signal. It is used mostly in digital cameras, camera modules and other imaging devices. Early analog sensors were video camera tubes, most currently used are digital charge-coupled device (CCD) or complementary metal–oxide–semiconductor (CMOS) active pixel sensors.

Famous quotes containing the word image:
“O love, my love! if I no more should see
Thyself, nor on the earth the shadow of thee,
Nor image of thine eyes in any spring,—
How then should sound upon Life’s darkening slope
The ground-whirl of the perished leaves of Hope,
The wind of Death’s imperishable wing?”
—Dante Gabriel Rossetti (1828–1882)
