Il pose un problème central d’opérabilité (modification des propriétés méca-niques et thermiques des parois, impuretés du plasma D-T, diminution de son coefficient d’émission) et de sûreté nucléaire(radioactivité du tritium). Ce piégeage est majoritairement piloté par l’état de surface et la composition des couches d’érosionredéposées sur ces parois à base de W ou de Be. The 1/2.8 sensors are in high demand for security cameras since they are compact and can fit just about anywhere.La fusion thermonucléaire de D et T pour former He entraîne la rétention des réactifs et des produits dans les matériauxde parois du tokamak. ※4 In addition, by employing a stacked structure with a low-noise circuit, Sony has made it possible to capture clear images even in dark scenes. ※4 This makes for a compact 1/2.8 sensor size, while still achieving superior low-light performance 1.5 times better than that of conventional CMOS image sensors. It employs proprietary high-sensitivity, low-noise technology to miniaturize the pixel size to 1.45 square μm, approximately 80% smaller than conventional. Sony developed this type 1/2.8 4K-resolution CMOS image sensor, the smallest of its kind in the world, ※1 for security camera applications. Main Features IMX415: World's smallest ※1 type 1/2.8 4K-resolution stacked CMOS image sensor for security cameras ※4: Compared to Sony's IMX274 type1/2.5, 8.51M effective pixels CMOS image sensor.Sony expects that these newly developed CMOS image sensors will be used for a variety of applications, and that this, in turn, will promote the adoption of 4K security cameras, thereby contributing to the expansion of the market. This enables superior image recognition and detection performance even in dark environments, making it an optimal solution for high-end 4K security cameras. By employing the latest pixel technology for low-noise capabilities, this sensor achieves an outstanding low-light performance 3.3 times higher than conventional ※2 for a 4K-resolution sensor. ![]() Sony is also releasing the IMX485, a back-illuminated CMOS image sensor with even better low-light performance. ※4 The result is the world’s smallest ※1 type 1/2.8 4K-resolution stacked CMOS image sensor yet with superior low-light performance. Sony's newly developed IMX415 stacked CMOS image sensor employs proprietary high-sensitivity, low-noise technology to miniaturize the pixel size to 1.45 square μm, which is approximately 80% smaller than conventional. In general, as pixel miniaturization progresses, the light collection efficiency per pixel deteriorates and sensitivity decreases. ※3: Based on image sensor effective pixel specification method.IMX485 type 1/1.2 (diagonal 12.86mm) 8.42Meffective pixels ※3 back-illuminated CMOS image sensor IMX415 type 1/2.8 (diagonal 6.43mm) 8.46Meffective pixels ※3 stacked CMOS image sensor ※2: Compared to Sony's IMX334, type 1/1.8, 8.42M effective pixels CMOS image sensor.※1: Among 4K-resolution CMOS image sensors for security camera applications.The expanded sensor lineup makes it possible to obtain high-quality images for various scenes, thereby expanding the range of applications for security cameras. Going forward, significant growth is also expected in demand for cameras for image recognition in anomaly detection and behavioral analysis using AI.Īddressing this need, Sony offers a lineup of compact 4K-resolution CMOS image sensors that deliver superior image recognition and detection performance and excellent low-light performance at the same time-which had been difficult to achieve with conventional technologies. There is an increasing demand for security cameras for use in a variety of places, and with that comes greater demand than ever for compact cameras that can be installed just about anywhere and have a higher level of image recognition and detection performance. ※2 Sony has designed these two new sensors for security cameras for the growing smart city market and to meet the rapidly expanding need for security cameras in a variety of monitoring applications such as anti-theft, disaster alert, and traffic monitoring systems or commercial complexes. Tokyo, Japan - Sony Corporation today announced the upcoming release of two new models of CMOS image sensors: the IMX415 type 1/2.8 4K-resolution stacked CMOS image sensor, which is the smallest of its kind in the world ※1 and the IMX485 type 1/1.2 4K-resolution back-illuminated CMOS image sensor, which delivers outstanding low-light performance approximately 3.3 times that of conventional. ![]()
