Sony LYTIA 610 Sensor announced with 64MP 1/2″ sensor, RB2×2 OCL Technology, 4K 120fps Recording Capability

Sony Semiconductor Solutions Corporation (Sony) has unveiled the new LYTIA 610, a 1/2-inch stacked CMOS image sensor developed for smartphone cameras. Featuring approximately 64 million effective pixels, the LYTIA 610 becomes the industry’s first mass-produced image sensor to adopt an RB2×2 On-Chip Lens (OCL) pixel structure.

RB2×2 OCL Pixel Architecture

A key highlight of the LYTIA 610 is its advanced pixel design, which is engineered to improve both image detail and autofocus performance. The sensor combines two different OCL configurations within a Quad Bayer pixel arrangement:

• 1×1 OCL Structure: Applied to Green (G) pixels, helping maximize image resolution and detail reproduction.
• 2×2 OCL Structure: Applied to Red (R) and Blue (B) pixels, where four pixels share a single lens. This setup enables phase-detection autofocus functionality, contributing to faster and more accurate focusing.

To fully utilize this hybrid architecture, Sony has developed a dedicated remosaicing algorithm that optimizes image processing. According to the company, the combination of the new hardware design and signal processing technology delivers more than a 20% improvement in spatial resolution compared to conventional Sony sensors with similar pixel dimensions. This makes the sensor particularly suitable for telephoto camera modules.

Enhanced Video Performance

The LYTIA 610 incorporates several improvements aimed at increasing data readout efficiency, including low-power logic circuitry and a redesigned parallel analog-to-digital (AD) converter. These enhancements enable readout speeds that are approximately twice as fast as Sony’s existing 1/2-inch image sensors.

With these upgrades, the LYTIA 610 becomes Sony’s first 1/2-inch sensor capable of recording 4K video at 120fps, allowing for smoother motion capture and higher-quality slow-motion footage. The sensor also supports 4K 60fps DAG-HDR video recording, helping preserve detail in scenes with challenging lighting and high contrast.

Sony says the new sensor is designed to narrow the performance gap between primary smartphone cameras and secondary camera modules such as telephoto and ultra-wide lenses, providing a more consistent imaging experience across multi-camera systems.

Key Specifications

Availability

Sony has confirmed that shipments of the LYTIA 610 to smartphone manufacturers will begin by the end of June 2026. Devices equipped with the new sensor are expected to arrive in the market later this year.
