The OV32C from OmniVision Technologies is a 32 Megapixel CMOS Image Sensor that is designed for front-facing mobile phone selfie cameras. It has a 1/3.2-inch optical format with 8/10 bit ADC that delivers a frame rate of 15 fps at full resolution and 30 fps at 8 MP resolution. This image sensor is based on OmniVision’s 0.7 μm PureCel Plus-S pixel technology and RGBC technology that provides high quality images in challenging lighting conditions, as well as providing a 50% boost in overall sensitivity to enhance low-light image quality. RGBC technology uses a 4-cell color filter pattern with clear pixels and an on-chip RGBC-to-Bayer fusion algorithm thus eliminating the need for a separate RGBC processing unit. 

The OV32C has an auto automatic black level calibration (ABLC) feature and supports dynamic defect pixel cancellation (DPC) and ambient light sensor (ALS) mode. It has three on-chip phase lock loops (PLLs) and a built-in temperature sensor. This image sensor requires a DC supply of 1.1 V (core), 2.8 V (analog) and 1.8/1.2 V (I/O) and consumes 450 mW of power. It supports low power modes enabling  “always-on” features optimizing the phone’s back-end AI applications, minimizing power and data rate usage. This sensor uses a 4-lane MIPI D-PHY TX interface with speed up to 3.0 Gbps/lane and a 2/3 trio C-PHY interface with speed up to 3.0 Gsps/trio for output. It is ideal for smartphones, video conferencing and PC multimedia applications.
