IMX249LLJ/IMX249LQJ Diagonal 13.4mm (Type 1/1.2) 2.35M-Effective Pixel Monochrome and Color CMOS Image Sensors 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, ash band phenomenon will occur and it might be a problem especially for the elds of ITS (Intelligent Trafc Systems) use. The new sensors feature a global shutter function and able to capture a highspeed moving image without focal plane distortion. Global shutter function Max frame rate : 30 frame/s (12 bit) Trigger mode (able to control accumulation time by external pulse) A variety of operating modes (V inversion output and multiple frame set output mode) * Exmor is a trademark of Sony Corporation. The Exmor is a version of Sony's high performance CMOS image sensor with high-speed processing, low noise and low power dissipation by using column-parallel A/D conversion. * Pregius is a trademark of Sony Corporation. The Pregius is global shutter pixel technology for active pixel-type CMOS image sensors that use Sony's low-noise CCD structure, and realizes high picture quality. 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, ash band phenomenon was inevasible in principle. (See photograph 1.) A new pixel with analog memory was developed for the IMX249LLJ/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). 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 2.) Trigger Mode The IMX249LLJ/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 condi- tions during shutter operation and can be coordinated with peripheral circuits. A Variety of Operating Modes The IMX249LLJ/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) and full HD scan mode as the image data output format.
