Abstract
A multipoint autofocus system includes a line sensor which receives object images and outputs a signal corresponding to a brightness thereof. The system also includes a controller having an A/D converter which converts the signal output from the line sensor to 10 bit digital data, and further converts the 10 bit digital data to one of 9 bit and 8 bit digital data, wherein a conversion precision of the A/D converter can be varied.
