CMOS IMAGE SENSER AND DIGITAL CAMERA INCLUDING THEREOF AND IMAGE SIGNAL DETECTING METHOD OF CMOS IMAGE SENSER |
摘要 |
A CMOS image sensor, a digital cameral including the same and an image signal detecting method of the CMOS image sensor are provided to connect an output of a pixel using no source follower directly to a comparator, thereby expanding a dynamic range and reducing noise. A CMOS(Complementary Metal Oxide Semiconductor) image sensor(100) comprises a timing controller(10), a pixel array unit(20), an ADC(Analog-Digital Converter)(30), and a buffer(40). The ADC comprises a comparator(31), a counter(32) and a lamp voltage generator(33). A switch transmits a signal, sensed by a photo diode, to a sensing node. The comparator is directly and electrically connected to the sensing node, and compares the sensed signal of the sensing node with a reference signal.
