8M Back Side Illumination CMOS Image Sensor

The RAA462113FYL is an 8M BSI CMOS image sensor for security applications. The sensor features HDR (High Dynamic Range) and AF Assist (Autofocus Assist) functions for performance at high contrast and variable ranges; it supports both MIPI-CSI2 or SLVS output formats, with support to 60fps (12-bit digital output).

Advantages

Superior Low Illumination Performance

  • The newly developed BSI techology achieves low noise and high sensitivity to improve the visibility of a color image in darkness.

 

Advanced High-speed Circuit Technology

  • 12-bit resolution at 60fps generates smooth movies.

 

Line-by-Line HDR Assist Function at 30fps

  • The sensor outputs long-exposure images and short-exposure images by each horizontal line enabling the ISP to synthesize the blended image to create pictures at 30fps while eliminating both blown-out highlights and blocked-up shadows.

Autofocus (AF) Assist Function with Built-in HPF

  • Contrast information calculated in 20 split image planes assists the autofocus system even without an ISP that supports AF function.

Low Illumination Performance Calculation Definition

Two light sources at a color temperature of 3200K illuminate 18% gray chart. CMOS image sensor is placed at a meter distance from the gray chart. Furthermore, lens and IR cut filter are installed on CMOS image sensor.

On the condition that exposure time is 1/60 sec and F number is F1.4,
SNR is calculated by the below formula:

Where G[e-] is signal intensity, the square of photon shot noise.
Low illumination performance means the intensity of illumination when SNR is equal to 1.
