The AAA2021N from SK Hynix is a 20 Megapixel CMOS Image Sensor with a 10-bit ADC in 1/2.8 inch optical format that delivers a frame rate of 30 fps @ 5184 x 3888 and 60 fps @ 2592 x 1944 resolution. It requires a DC supply of 1.1 - 2.8 V and consumes 242 mW of power @ 30 fps and 227 mW @ 60 fps. This sensor can be controlled via a two-wire serial bus interface and uses a MIPI 2/4-Lane interface for output. This image sensor uses unique sensor technology to enhance image quality by reducing FPN (Fixed Pattern Noise), horizontal/vertical line noise, and random noise.
The AAA2021N has a built-in temperature sensor, internal PLL for high-speed clock generation, and built-in test pattern generation. It supports dual camera synchronization (FSYNC), dead pixel correction, 2D lens shading correction, black level calibration, and can produce 10-bit Quad Bayer/Sum Bayer output. This image sensor uses 1 µm Intensive Pixel Technology to capture clear photos in low light conditions and realistic images with improved noise characteristics. It has Paired PDAF (Phase Detection Auto Focus) to ensure greater image quality and a re-mosaic algorithm for real-time conversion between resolution-centric and quality-centric camera modes depending on the lighting conditions.
This image sensor has Dual Conversion Gain (DCG) Pixels that automatically adapt the camera to surrounding lighting conditions, enabling steady production of high-quality and high-ISO images even when the lighting rapidly shifts. It has a flash strobe control that supports Xenon/LED flash types and is ideal for mobile phone cameras, digital still cameras, PC cameras, and video conference applications.
