CMOS Image Sensors with Global Shutter Function for Industrial Use

In such cases where a high-speed moving subject is to be shot with standard CMOS Image sensors, focal plane distortion will occur and it might be a problem especially for the fields of industrial use. The new sensors feature a global shutter function and able to capture a high-speed moving image without focal plane distortion. Also the sensors have various functions including trigger mode or ROI (Region of interest) mode specially required in the fields of industrial use.

- Global shutter function

- High frame rate (10 bit 164.5 frame/s, 12 bit 128.2 frame/s)

- ROI mode (able to set at a maximum of 16 areas)

- Trigger mode (able to control accumulation time by external pulse)

- A variety of operating modes (V inversion output and multiple frame set output mode)

Global Shutter Function

For industrial use, it is required to capture the exact shape of a high-speed moving subject. The existing CMOS image sensors have a rolling shutter as the electronic shutter function; therefore, focal plane distortion was inevasible in principle. A new pixel with analog memory was developed for the IMX174LLJ/LQJ and eliminated generation of the focal plane distortion by enabling to scan all pixel signals at once (referred to as "global shutter function" below). (See moving image 1.) The sensors accomplished high-picture quality combining with the column-parallel A/D conversion technology used for the existing Sony's CMOS Image sensors. (See photograph 1.)

High Frame Rate

For industrial use, it is required to capture the sequence of high-speed moving subject; therefore, frame rate is equally important as global shutter function. The IMX174LLJ/LQJ optimized the internal circuit and adopted LVDS 8ch output, and then realized high-speed imaging by achieving high frame rate with a maximum 164.5 frame/s using 10 bit ADC, and with a maximum 128.2 frame/s using 12 bit ADC. (See table 3.)

ROI Mode

To meet market needs, there is a requirement to capture moving subject only in partial areas rather than a whole image view angle. ROI mode makes this possible. The IMX174LLJ/LQJ have the ROI mode and able to set at a maximum of 16 areas inside the effective pixels and output cropped partial pictures out of the image view angle. Also, since ROI mode scans less pixel count, even higher frame rate is achievable. (See photograph 2.)

Trigger Mode

The IMX174LLJ/LQJ are equipped with trigger mode, and the external pulse can control accumulation time. The sensors also have a pulse output function to indicate respective conditions during shutter operation and can be coordinated with peripheral circuits.

A Variety of Operating Modes

The IMX174LLJ/LQJ have internal register settings which can switch vertical scan direction (normal/inverted) of the sensors and support 2 frame set output mode utilizing high-speed frame rate. In this 2 frame set output mode, separate exposure time can be set for 2 consecutive frames, and each set of 2 frames can be handled as 1 set to automatically output consecutive images. This mode can generate a picture with a wide dynamic range as a result of the combination of multiple frames. Also the sensors support all-pixel scan (WUXGA), including UXGA, and full HD scan mode as the image data output format.
