The IMX294 image sensor from SONY is designed to meet the needs of the security segment. The new flagship model size 4/3" is optimized to be used in security cameras and industrial applications. The back-illuminated CMOS Starvis sensor achieves a 4K resolution with 10.7 megapixels at a high frame rate of 120 fps. Available from the global imaging specialist FRAMOS, IMX294 has an excellent SNR1s* value and enables HDR shots with minimal movement artifacts thanks to the Quad Bayer pixel structure.
The image sensor adopts the standardized 4/3" optical format.. It offers various combinations of output formats: 10 megapixels (3,704 x 2,778) for 4:3 ratio, UHD (3,840 x 2,160) for 16:9 and 4,096 x 2,160 pixels for the 17:9 image format. Depending on the application’s requirements, it is possible to select a color depth of 10, 12 or 14 bits. The extraordinary low-illumination performance of 0.14lx for SNR1s is achieved by the large 4.63 µm pixel size . This makes IMX294 ideal for applications with low incident light, eliminating the need of additional illumination.
The IMX294 uses a Quad Bayer structure which outputs 2x2 binned pixels in normal mode. In HDR mode, two pixels of the quad array are used for a short exposure and the other two for a long one (Fig. 1). This eliminates the temporal delay between short and long exposures seen in common two image HDR implementations, resulting in HDR images with minimal artifacts when imaging moving objects.
The industry and product experts at FRAMOS have specialized knowledge ranging from sensor to full imaging system, and provide complete support for the integration of new sensors into their applications. The Sony IMX294 works well with lenses such as the LMXC series from Kowa, as well as the Computar MPY series. FRAMOS also offers additional services such as development support, cover glass removal, as well as storage and logistics services.
