First Claim
Patent Images
1. An image sensor with a spectrum sensor, comprising:
- an image sensor region having a plurality of light-detection parts;
a spectrum sensor region located in the image sensor region; and
an image signal processor analyzing and processing an image which is obtained by the image sensor region and a spectrum signal which is obtained by the spectrum sensor region, the image signal processor being configured to compute a reflection or transmission rate of an object with respect to a band of a band pass filter,wherein the spectrum sensor region comprises;
a first spectrum sensor region for obtaining a reference signal for checking a current lighting condition; and
a second spectrum sensor region for obtaining a spectrum signal of the object that passed the band pass filter on a light-detection part for the spectrum sensor region.
