摘要 |
An electronic apparatus includes a CMOS image sensor and a signal processor operable to process an output signal from the CMOS image sensor. The CMOS image sensor includes the following elements: an imaging region; a reference signal generator operable to generate a reference signal; a comparator operable to compare the reference signal generated by the reference signal generator with a signal transmitted from the imaging region; a counter operable to count, in parallel with comparison performed by the comparator, a predetermined count clock and to hold a count value at the time of completion of comparison performed by the comparator; and a reference signal supply interface unit operable to supply the reference signal generated by the reference signal generator to a plurality of comparators via different signal lines, respectively.
