Full HD CMOS Image Sensors for Industrial Applications Featuring Higher Sensitivity with White (W) Pixel

Sony adopted a white (W) pixel for the industrial applications and developed the IMX136LAJ and IMX140LAJ, full HD CMOS image sensors with high sensitivity.
Adding the white (W) pixel, compared with Sony's existing Bayer array products, the IMX136LQJ and IMX140LQJ, the sensitivity increased by +3.5 dB.
A versatile interface means that the sensor can be tailored to different applications.
Using the most suitable DSP to the products, system configurations will be easier.

  • Adding a white (W) Pixel
  • High sensitivity (+3.5 dB compared with Bayer array products)
  • Supporting full HD1080p mode
  • Built-in 10 and 12-bit A/D converters
  • Multiple frame set output mode

High Sensitivity with a White (W) Pixel

In the industrial applications market, the demand for full HD sensors with high sensitivity has increased over the years.
This time, Sony developed the IMX136LAJ and IMX140LAJ with higher sensitivity by +3.5 dB compared with the conventional products with Bayer array, IMX136LQJ and IMX140LQJ.
While keeping the high sensitivity with a white (W) pixel, suppression of the color mixture enables the same level of color reproducibility as Bayer array products.
It also increased incident light angle characteristics from the conventional product of IMX103LAR with the white (W) pixel, the color reproducibility dramatically improved in the dark areas with surveillance cameras at a lower F-number.

A Variety of Operating Modes

In addition to the all-pixel scan mode and full HD1080p mode in the IMX136LQJ and IMX140LQJ, the window cropping mode is also supported.
The IMX136LAJ output interface has a CMOS low-voltage LVDS parallel interface and a 4ch low-voltage LVDS serial interface. The IMX140LAJ has MIPI (CSI-2 compliant) 4 lane, which works as a high-speed serial interface. (See table 3.)
Also the control interface has been modified to include a general-purpose I2C interface besides 4-wire serial interface, and provides customers with options to suit their operating conditions.
The functions support the multiple frame set output mode to take advantage of the high-speed frame rate. And separate exposure time and gain can be set to the consecutive 4 or 2 frames.
Combined data output from those functions enables a wide dynamic range.

Package

The image sensors are provided in a LGA (Land Grid Array) package that can withstand high-temperature reflow soldering (peak temperature: 240°C).
The package is same as Sony's existing products, the IMX139LQJ and IMX140LQJ and pin compatible, so they can be easily deployed in lineup products with high sensitivity.

DSP Compatible

Optimized Sony's DSPs are available to make good use of the high sensitivity of the IMX136LAJ and IMX140LAJ. The combinations make easier to develop high sensitivity camera environment. (See table 4.)
