The following content summarizes the differences between the Full HD 1080P Sony Starvis IMX307 and Sony Starvis 2 IMX662 image sensors,as analyzed and compiled by Standtop engineers.this information provides valuable reference for customers in selecting suitable Reverse or Surveillance cameras, ensuring driving safety.

Introduction: The Night Vision Revolution

    Sony’s Starvis series of CMOS image sensors has become a benchmark in surveillance, automotive, and industrial imaging.The Sony IMX307 sensor is a workhorse, a widely adopted sensor built on the original STARVIS platform. But now, the next generation is here: the Sony IMX662, featuring the STARVIS 2 technology.

Comparison Table

1. The Core Technology: STARVIS vs. STARVIS 2

The biggest difference lies in the underlying image processing architecture.

The key innovation in STARVIS 2 is the ability to capture a wider dynamic range in a single exposure compared to the first-generation STARVIS sensors, which often rely on complex multi-exposure High Dynamic Range (HDR) techniques.

2. High Dynamic Range (HDR) and Motion Clarity

Both sensors feature High Dynamic Range (HDR) functionality to handle complex lighting, but the IMX662 introduces a superior method.

• IMX307 (STARVIS): Often uses Digital Overlap HDR (DOL-HDR). This method captures multiple frames with different exposures in quick succession and combines them. While effective, capturing frames sequentially can lead to motion artifacts like ghosting or chromatic aberration (color fringing) when a fast-moving object is in the frame.

• IMX662 (STARVIS 2): Supports Clear HDR. This advanced method is designed to synthesize the high- and low-gain images simultaneously, which dramatically reduces the chance of chromatic aberration or blurring artifacts when capturing fast-moving objects like a car on the highway.

3. Speed, Sensitivity, and Power Consumption

While both sensors are Full HD (1920x1080 resolution) and have a similar optical format (Type 1/2.8), the IMX662 has performance upgrades that make it a more versatile choice:

• Max Frame Rate (10-bit output): The IMX662 can achieve up to 90 frames per second (fps) in its basic drive mode, a significant increase over the IMX307's maximum of 60 fps. This higher frame rate is essential for capturing every detail in high-speed applications like traffic monitoring.

• Sensitivity: The IMX662 boasts a much higher sensitivity than its predecessor, meaning it can capture a usable image in even lower light levels, further solidifying its "starlight" capability.

• Power Consumption: Despite its performance enhancements, the IMX662 is designed with a focus on low power consumption, making it highly suitable for 24/7 security systems and battery-powered IoT devices.

Conclusion: Which Sensor is Right for You?

The Sony IMX307 is a proven, reliable, and cost-effective sensor that delivers excellent low-light performance (hence its popularity in budget-to-mid-range starlight cameras).

However, the Sony IMX662 represents a genuine technological leap forward. As part of the STARVIS 2 generation, it offers:

• Superior Clarity: Less noise in the deepest shadows.

• Wider Dynamic Range: Better detail capture in both bright and dark areas simultaneously.

• Cleaner Motion Capture: The new Clear HDR virtually eliminates motion artifacts in high-contrast scenes.
