Sony has announced the industry’s first to three-layer CMOS image sensor for smartphones, which provides verzamelen video. iPhone with this sensor will be able to shoot Full HD video at 1000 frames per second.
The latest generation of image sensors Canon releases in the form of two-layer structures. In the upper layer of the sensor with the filters and microlenses is an array of photodiodes with back-illuminated, at the bottom – the logic that processes raw data from sensors and managing the sensors. New Sony module is a three-tier, where the average “intermediate” layer is an array of DRAM memory capacity of 1 GB.
The use of capacious DRAM buffer allows you to bypass the limitation of the interface to transfer raw data into the processor for image processing. In other words, during high speed shooting data is written to the buffer as the processing is transferred to the processor without any loss in the form of skipped frames. This approach, among other things, provides the ability verzamelen shooting video, previously impossible on smartphones.
The iPhone 7 and iPhone 7 Plus, with some of the best mobile cameras on the market allows for time-lapse movies with a maximum speed of 120 fps in Full HD and 240 fps in 720p. By the way, 1000 fps is more than a camera Sony RX 100 V, which removes high with a velocity of 960 fps.
The photosensitive layer of three-layer matrix consists of 21.2 Sony effective megapixels with a resolution of 5520 × 3840. The size of the diagonal of the matrix of 7.73 mm (ratio of 1/2,3). The size of the photosensitive cells equal to 1.22 × 1.22 µm. Static images can be taken at 30 frames per second with an aspect ratio of 4:3 (19,3 MP) and 16:9 (17,1 MP). Video allows shooting at 60 fps with 4K resolution (3840 × 2160) and 240 fps 1080p and 720p (short-term shooting is possible at up to 1000 frames per second).
Sony have not yet called the timing of production of new sensors. As the company is the official supplier of Apple’s new CMOS module can be used in future iPhone models.
