Sony Semiconductor Options to Launch Business’s First*1 CMOS Picture Sensor for Safety Cameras That Concurrently Delivers Full-Pixel Output of
Captured Pictures and Excessive-Velocity Output of Areas of Curiosity
Atsugi, Japan — Sony Semiconductor Options Company (SSS) right now introduced the upcoming launch of the IMX675, a 1/3-type CMOS picture sensor for safety cameras with roughly 5.12 megapixels*2 that concurrently delivers each full-pixel output of the entire captured picture and high-speed output of areas of curiosity.
In an business first,*1 the brand new sensor from SSS leverages Twin Velocity Streaming know-how to output all the pixels in a captured picture at a most charge of 40 frames per second whereas concurrently outputting particular user-set areas of curiosity at excessive pace. Utilizing this picture sensor permits a single digicam not solely to supply complete photographs of scenes, but in addition to assist high-speed recognition of particular objects at a excessive stage of element.
The brand new sensor additionally employs distinctive STARVISTM 2 know-how from SSS, which delivers high-sensitivity and a large dynamic vary, however with roughly 30% much less energy consumption than standard fashions,*3 due to its proprietary stacked construction.
These applied sciences come collectively to ship high-performance, high-quality picture seize no matter utilization circumstances or time of day, thereby contributing to a safer, safer society.
*1 Amongst CMOS picture sensors for safety digicam functions. As of announcement on July 20, 2022.
*2 Primarily based on picture sensor efficient pixel specification technique.
*3 In comparison with SSS’s IMX335 1/3-type 5.12 efficient megapixel CMOS sensor.
The necessities for safety cameras differ relying on the place and the way they’re used. On the similar time, protecting the variety of cameras optimized at a minimal is important to maintain system prices low.
Due to proprietary Twin Velocity Streaming know-how from SSS, the brand new sensor can concurrently output the entire captured picture and particular areas of curiosity at totally different body charges, enabling seize of a complete picture of the scene whereas additionally precisely recognizing quick-moving objects, all with a single digicam. This design helps scale back system prices. The brand new sensor can be utilized to seize, for instance, the entire picture of an intersection whereas recognizing folks and automobiles transferring by means of it, or to seize an total picture of a freeway whereas additionally capturing the small print wanted to determine the license plate numbers of automobiles travelling on it.
Moreover, STARVIS 2, a know-how which delivers excessive sensitivity and a large dynamic vary, however with roughly 30% much less power consumption than standard fashions,*3 permits a dynamic vary of 78 dB, roughly 2.5 occasions that of standard fashions,*3 when utilized in a single publicity technique. Consequently, the brand new sensor product has potential functions past safety cameras, for example in drive recorders and webcams, each of that are seeing growing demand in latest occasions.
Most important Options
■Geared up with Twin Velocity Streaming for simultaneous full-pixel output of captured photographs and high-speed output of particular areas of curiosity
This picture sensor is the business’s first*1 to make use of Twin Velocity Streaming know-how to concurrently output all pixels in a captured picture at a most charge of 40 frames per second whereas additionally studying particular areas of curiosity at a excessive body charge, a feat made doable by its authentic readout circuits. The placement of the area of curiosity within the body might be specified vertically, along with the corresponding body charge. Relying on the aim, customers can select to learn solely the mandatory area at excessive pace to reduce the load on the digicam system at a later stage by decreasing the quantity of knowledge in comparison with the standard technique of studying all pixels.
Instance of body charge and area of curiosity vertical specification
■Consumes 30% much less energy than standard fashions*3
This product makes use of a stacked construction, using a Cu-Cu connection*4 between the pixel unit and circuit unit, to attain an optimized format for a number of high-speed sign processing circuits. This ends in considerably decrease energy consumption, roughly 30% decrease than standard fashions.*3 In lots of circumstances, safety cameras function across the clock, creating points equivalent to energy consumption prices, influence on the setting, and digicam warmth technology. With this new sensor, the variety of heatsink parts within the digicam system might be decreased, decreasing the general system value and contributing to decreasing the influence on the setting.
*4: Know-how that gives electrical continuity through related Cu (copper) pads when stacking the pixel part (prime chip) and logic circuits (backside chip). In contrast with through-silicon through (TSV) wiring, the place the connection is achieved by electrodes intruded across the circumference of the pixel space, this technique provides extra freedom in design, improves productiveness, permits for a extra compact dimension, and will increase efficiency.
■Single publicity technique with roughly 2.5 occasions wider dynamic vary than standard fashions*3
The brand new picture sensor employs STARVIS 2 know-how developed by SSS, which makes use of distinctive processing know-how to extend the realm of the light-receiving unit regardless of pixel dimension limitations, leading to a large dynamic vary in a 1/3-type 5.12 megapixel format. This design delivers a dynamic vary roughly 2.5 occasions wider than standard fashions,*3 at 78 dB, thereby enabling high-precision monitoring.
■Improved sensitivity within the near-infrared area delivers high-quality photographs in darkish places
The brand new product comes with a proprietary system construction from SSS, the place irregularities are included into the incidence planes of the sunshine receiving unit to refract incident mild and thereby improve the absorption charge of invisible close to infrared mild. This design ends in a sensitivity roughly 2.5 occasions larger than standard fashions,*3 making it doable to seize high-quality photographs even in close to infrared conditions, which is commonly utilized in darkish scenes and at evening.
