Patent ID: 8854535

Claim:
An imaging device comprising, comprising: a fixed focus lens; an image sensor that includes: an image matrix on a semiconductor substrate, the image matrix including a plurality of pixels arranged in rows and columns; first and second ambient light sensors arranged on opposite sides of the image matrix to capture an ambient light intensity through the fixed focus lens, each ambient light sensor including a plurality of pixels arranged in at least one row and N columns; and a reading circuit coupled to the image matrix and the first and second ambient light sensors to select and read the first and second ambient light sensors and the image matrix, and to supply ambient light data with image data; and a processing unit to process both the ambient light data and the image data and to generate an ambient light data result based on at least one of the following: an average of ambient light data from the first ambient light sensor and ambient light data from the second ambient light sensor; a maximum of the ambient light data from the first ambient light sensor and the ambient light data from the second ambient light sensor; a minimum of the ambient light data from the first ambient light sensor and the ambient light data from the second ambient light sensor; and a sum of a weighted value of the ambient light data from the first ambient light sensor and a weighted value of the ambient light data from the second ambient light sensor.
