Image Sensors Enhance High-End Smartphone Cameras

OmniVision Technologies’ second generation OV24B sensor family of 0.9 micron, 1/2.83-inch optical format 24-megapixel (MP) image sensors are built on the PureCel Plus stacked die technology. The OV24B sensor family is designed for high-resolution front- and rear-facing smartphone cameras, with technologies that enable differentiated features and high-end imaging performance.

 

The image sensor family is available in four versions:

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.
  1. OV24B1Q: 4-cell Bayer imaging; in-pixel binning for optimal sensitivity and low-light performance; and pad locations on the top and bottom of the chip to reduce module size in the x-direction, ideal for front-facing cameras in thin-bezel infinity display phones
  2. OV24B2Q: 4-cell Bayer imaging; in-pixel binning; type-2, 2x2 microlens phase detection autofocus (ML PDAF), ideal for main cameras due to video and low-light performance
  3. OV24B1B: monochrome imaging; excellent low-light sensitivity; ideal for rear-facing multi cameras for Bokeh and zoom
  4. OV24B10: standard Bayer imaging; ideal for main cameras due to high 24MP resolution, as a single camera or as part of a multi-camera arrangement for Bokeh and zoom

The on-chip re-mosaic feature, available in the OV24B1Q and OV24B2Q, makes it possible to have real-time conversion between high-performance quarter resolution and full resolution 24-MP outputs. This feature provides greater viewfinder accuracy and a fast, seamless transition between taking still images and video.

 

The OV24B2Q’s 2x2 ML PDAF enables faster autofocusing over standard PDAF, even in extremely low light conditions. All four versions can output high-resolution streaming video in a variety of formats, including 24 MP at 30 fps, four-cell binning 6 MP at 60 fps, 4K2K video at 60 fps, 1080p video at 120 fps, or 720p video at 240 fps.
