IMAGE SENSOR USING NEAR INFRARED SIGNAL

摘要

PURPOSE: An image sensor using a near infrared signal is provided to minimize color distortion by using a color signal corresponding to a visible area and the near infrared signal. CONSTITUTION: A filter unit(201) passes light corresponding to a visible area and light corresponding to a first area of a long wavelength band, and blocks light corresponding to a second area of a longer wavelength band than the first area. A sensor unit(203) senses light passing through the filter.
