Rising demand for camera enabled devices such as tablets, phones, PC and digital camera is expected to drive the image sensors market. Optical images are converted into electrical signals by image sensors which have replaced the traditional cameras. Increasing digital cameras in the recent years is expected to further fuel the market demand. Digital cameras use light cavaties and array of photosites to record the image. Depending upon the image sensor, the camera uses the light to create an image. Depending upon the sensors the quality of the image varies. Larger sensors are used in digital cameras for better picture quality and small image sensors are used in mobile phones. Additionally, digital cameras such as DSLRs are also fitted with interchangeable lens with large sensors.
Technology includes complementary metal–oxide–semiconductor (CMOS), charge-coupled device (CCD) and contact image sensors (CIS). CCD technology helps image sensors to charge the capacitors automatically by absorbing the light which is converted to numerical value to produce the image. These sensors are widely used by scientific and medical devices. CMOS image sensors have transistors which contains a photo detector that absorbs light and is converted to optical signal. In low light sensitivity, CMOS sensors enable electronic pan, stabilization and tilt to get high quality images. Image sensors are portable which consume lesser power and cost efficient when compared with the other products. The sensors cannot be used for scanning. Technological advancements in consumer electronics have driven the market demand. CIS used for scanning a document by directing the gathered light from green, blue and red. These sensors are used in smaller components as they require less power and their compact nature.
Applications include consumer electronics, automotive, aerospace & defense, surveillance, medical, industrial and others. They are also used for scanning a document. Automotive image sensors are used for scene processing and scene viewing. Decreasing parking spaces have led to the adoption of parking sensors in vehicles. Usage of reverse parking camera prevents drivers from potential accident, which is expected to drive the market demand over the forecast period. The sensors can detect walls, children, pillars and fences, which is expected to provide positive avenues to market demand in the coming years. Increasing demand for consumer electronics such as tablets, smartphones and PCs is expected to provide positive avenues to market growth rate over the next five years. Growing usage of cameras in defense sector is expected to fuel the market demand in the near future. Some systems need to run on batteries in the field by which CMOS sensors use on very less power which plays a vital role for market demand. Image sensors are used for facilitating ophthalmology and digital radiography. For example, these are used in fundus cameras. The health care segment is expected to boost the market growth over the next few years. Video surveillance for detecting unlawful activities is expected to drive the market demand.
North America and Europe is expected to grow at a significant rate. Asia-Pacific is expected to grow considerably over the forecast period. Increasing awareness of application of sensors, growth in automobile industry and favorable government rules and regulations are the factors expected to drive the parking sensors market in India over the forecast period.
The key players in the image sensors market include Aptina Imaging, Samsung Electronics Co., Ltd., Sony Corporation, Canon Inc., Fujifilm, CMOSIS, Sony and others. Sony invested USD 340 million to boost the sensor technology for smart phone market.
