IMX294CJK Diagonal 21.63 mm (Type 4/3) Approx. 10.71M-Effective Pixel Color CMOS Image Sensor High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Security Camera and Industrial Applications Sony Semiconductor Solutions Corporation has commercialized the "IMX294CJK" Type 4/3 back-illuminated CMOS image sensor with approximately 10.71M-effective pixels for the expanding security camera market. The "IMX294CJK" is the ﬁrst in-house image sensor for security cameras to adopt the Type 4/3 format, and realizes output of the number of pixels needed for 4K at 120 frame/s (in ADC ■ Large-size ■ Supports ■ High *1: Low illuminance performance index advocated by Sony for image sensors for industrial applications optical format (Type 4/3) 10-bit output mode). In addition, use of a large-size pixel achieves SNR1s of 0.14 lx*1, and use of a Quad Bayer pixel structure (see Figure 1) realizes an HDR (High Dynamic Range) function with no time difference, enabling video imaging with a wide dynamic range. *Exmor R is a trademark of Sony Corporation. The Exmor R is a Sony's CMOS image sensor with significantly TM enhanced imaging characteristics including sensitivity and low noise by changing fundamental structure of Exmor pixel adopted column parallel A/D converter to back-illuminated type. Quad Bayer Coding HDR *2: Scalable Low Voltage Signaling Embedded Clock *STARVIS is a trademark of Sony Corporation. The STARVIS is back-illuminated pixel technology for CMOS image sensors for surveillance camera applications. It features a sensitivity of 2000 mV or more per 1 μm2 (color product, when imaging with a 706 cd/m2 light source, F5.6 in 1 s accumulation equivalent), and realizes high picture quality in the visible-light and near infrared light regions. Supports Type 4/3 4K output The IMX294CJK adopts Type 4/3 as the optical size, and supports various output formats (angle of view) including 10M (3704 × 2778) for aspect ratio 4:3, UHD (3840 × 2160) for 16:9, and 4096 × 2160 for 17:9. In addition, the A/D converter can be selected from 10 bits, 12 bits, and 14 bits according to the application (Table 3). Exceptional low-illumination performance Exceptional low-illumination performance of SNR1s: 0.14 lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 μm. This makes the IMX294CJK ideal for security camera market applications that require low-illumination performance (Photograph 2). High-speed movie imaging This product realizes high-speed movie imaging with a 4K angle of view at the high frame rate of 120 frame/s, and also enables high-speed imaging at 60 frame/s in HDR drive mode. In addition, use of our proprietary high-speed serial interface SLVS-EC together with high-speed imaging enables image transfer with few signal lines. This product is also equipped with a general-purpose MIPI (CSI-2) interface, and supports connection with a general-purpose ISP (Image Signal Processor). Quad Bayer Coding HDR The IMX294CJK uses a Quad Bayer structure, and outputs data binned in 2 × 2 pixel units in normal mode. In HDR mode, integration can be divided into long-time integration and short-time integration for each 2 pixels in the Quad array (Figure 1). In this case there is no time difference between long-time integration and short-time integration, which realizes HDR with little blending offset when imaging moving subjects (P
