乔迁大吉祝福语Industrial applications demand imaging of fast-moving subjects. However, there is the issue that existing CMOS image nsors are unable to accurately identify fast-moving subjects due to focal plane distortion as a result of rolling shutter opera-tion. To address this issue, Sony has developed C
MOS image nsors with a global shutter function and a 3.45 μm pixel that is the smallest class in the industry. This small-sized 3.45 μm

In addition, the new CMOS image nsors are equipped with a variety of functions such as a trigger mode that arbitrarily controls the storage time using an exter-nal trigger signal, and ROI (region of interest) mode.
Industrial applications require imaging of fast-moving subjects. However, there is the issue that existing CMOS image nsors are unable to accurately identify fast-moving subjects due to focal plane distortion as a result of rolling shutter
operation. The IMX250LLR/LQR and IMX252LLR/LQR address this issue by providing analog memory inside each pixel and realizing a global shutter function, which enables high-picture-quality imaging without focal plane distortion.
Analog memory, transistors and other elements must be added to the inside of each pixel to realize a global shutter function, which made it a challenge to reduce the pixel size. The newly developed products u Sony's fine pixel fabrication
technology to realize a small pixel with a size of 3.45 μm compared to the 5 μm range that is the existing standard for global shutter pixels. This enables high-resolution imaging using a smaller lens
than that of the existing products.
littering
In order to reduce the size of pixels equipped with a global shutter function, it is necessary to cure a suf ficient pixel light-detecting area while also curing an analog memory area within the pixel, so there were concerns over a drop in nsitivity.
However, high-nsitivity pixel design technology and condensing process technology were ud to increa the nsitivity of the newly developed 3.45 μm
pixel, and realized high nsitivity exceeding that of the existing 5.86 μm product (1.1 times compared to the existing 5.86 μm product).
In addition, EXview HAD CCD*1 technology also increas nsitivity in the near-infrared range, enabling u with high picture quality even under near infrared light.

High Frame Rate
Customers have strongly demanded higher frame rates for industrial applications, so an ADC 8-bit m
ode was added to the IMX250LLR/LQR and IMX252LLR/LQR in addition to the existing ADC 10-bit and 12-bit modes. Also, the column-parallel A/D conversion technology of Sony CMOS image nsors is ud to realize
high-speed imaging of up to 163.4 [frame/s] (ADC 8-bit) for the IMX250LLR/LQR and up to 216.3 [frame/s] (ADC 8-bit) for the IMX252LLR/LQR (Table-3). This enabled further increasing the processing speed for industrial applications.
五四运动口号A Variety of Functions
The IMX250LLR/LQR and IMX252LLR/LQR are equipped with a variety of functions needed for industrial applications, such as ROI mode and trigger mode. ROI mode crops arbitrary areas, and up to 8 × 8 = 64 locations can be t. Various exposure methods are provided for trigger mode, which controls the exposure time using an external pul. In addition, the IMX250LQR and IMX252LQR (color
products) are equipped with functions such as subsampling, horizontal and/or vertical inverted readout, and multiple frame t output, and the IMX250LLR and IMX252LLR (monochrome products) also have a pixel addition function in addition
to color product functions.
