CMOS Image Sensors with a 3.45 µm Pixel and Global Shutter Function for Industrial
Applications
Sony has developed the IMX253LLR/LQR optical size Type 1.1 CMOS image sensor with
approximately 12.37 M effective pixels for industrial applications. The CMOS image sensor,
which features a global shutter function and a 3.45 µm pixel that is the smallest class in
the industry*1, achieves high picture quality, high resolution, and high-speed imaging
without distortion. Other features include a trigger mode that arbitrarily controls the
storage time using an external trigger signal, an ROI (Region of interest) mode for
cropping only the required region for output of image data, and functions required
by machine vision cameras.
The IMX255LLR/LQR, a Type 1 CMOS image sensor with approximately 8.95 M
effective pixels, uses the same package as the IMX253LLR/LQR to ensure pin
compatibility. In addition, the IMX255LLR/LQR can cover 4K pixels, making it
suitable not only for industrial applications but also for traffic surveillance and
other specialized uses.

Global Shutter Function
Industrial applications require accurate imaging of fast-moving subjects, but conventional rolling
shutter type image sensors have trouble properly capturing fast-moving subjects due to problems
such as flash bands and the distortion of the subject due to focal plane phenomena
The IMX253LLR/LQR and IMX255LLR/LQR are equipped with a global shutter-compatible pixel
, enabling high-quality image capture that is not affected by focal plane distortion and flash bands.
High Picture Quality/High Resolution
The IMX253LLR/LQR is an optical size Type 1.1 CMOS image sensor with approximately 12.37 M
effective pixels. With more than twice the pixels of the IMX250LLR/LQR, our existing product
employing the same pixel technology*2 (with approximately 5.07 M effective pixels), the
IMX253LLR/LQR is suited for subjects and scenes that require higher resolution. Also, the
IMX255LLR/LQR, which covers 4K pixels in a Type 1 optical size, can also be used for
applications such as traffic surveillance. Whereas conventional traffic cameras must be
installed one per lane, the IMX255LLR/LQR can capture multiple lanes with a single camera
while maintaining the same resolution.

High Frame Rate
In response to the growing demand for higher frame rates for industrial applications, the
column-parallel A/D conversion technology of Sony CMOS image sensors was used to
realize a frame rate of up to 68.3 frame/s (ADC 8-bit) for the IMX253LLR/LQR, and up to
93.7 frame/s (ADC 8-bit) for the IMX255LLR/LQR. This enabled further increasing the
processing speed for industrial applications.
A Variety of Functions
The IMX253LLR/LQR and IMX255LLR/LQR are equipped with a variety of functions needed
for industrial applications, such as trigger mode and ROI mode. There is an ROI mode for
cropping a desired region for output, which in addition to setting the conventional 8 × 8 = 64
locations, features greater freedom for specifying regions to allow overlap of specified regions
. Various exposure methods are provided for Trigger mode, which controls the exposure time
using an external pulse, Fast Trigger mode, which reduces the delay from trigger input until
the start of exposure, Multi Exposure mode, and other modes. In addition, the IMX253LQR
and IMX255LQR (color products) are equipped with functions such as subsampling, horizontal
and/or vertical inverted readout, and multiple frame set output. The IMX253LLR and IMX255LLR
(monochrome products) also have a vertical/horizontal pixel addition function in addition to color
product functions.
Compatibility with existing Sony products
The IMX253LLR/LQR and IMX255LLR/LQR facilitate an expanded lineup for customers by
aligning the optical center and back pin layout of the package with the IMX250LLR/LQR
(with 5.07 M effective pixels), which is already in production.
