Patent number: 9344627Abstract: An image sensor includes a pixel array and an analog-to-digital (A/D) conversion unit. The pixel array generates an analog signal by sensing an incident light. The A/D conversion unit generates a digital signal in a first operation mode by performing a sigma-delta A/D conversion and a cyclic A/D conversion with respect to the analog signal and generates the digital signal in a second operation mode by performing a single-slope A/D conversion with respect to the analog signal. The image sensor provides a high-quality image in a still image photography mode and a dynamic image video mode.Type: GrantFiled: December 13, 2013Date of Patent: May 17, 2016Assignee: Samsung Electronics Co., Ltd.Inventors: Kwi-Sung Yoo, Yu-Jin Park, Jae-Hong Kim, Jin-Ho Seo, Wun-Ki Jung, Han-Kook Cho, Seog-Heon Ham, Min-Ji Hwang
