    Abstract: 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.

    Abstract translation: 图像传感器包括像素阵列和模数(A / D)转换单元。 像素阵列通过感测入射光产生模拟信号。 A / D转换单元通过对模拟信号执行Σ-ΔA/ D转换和循环A / D转换,以第一操作模式产生数字信号,并通过执行第二操作模式生成数字信号 相对于模拟信号的单斜率A / D转换。 图像传感器在静态图像拍摄模式和动态图像视频模式中提供高质量的图像。
