240fps 4-megapixel CMOS image sensor

Photobit Technology has introduced the PB-MV40, claimed to be the world’s fastest 4-megapixel CMOS image sensor.

The sensor captures images at speeds of up to 240 frames per second (fps) at full resolution, resulting in a throughput of a gigabyte per second.

The PB-MV40 is suitable for a range of applications including electronics inspection, automotive crash testing, microscopy, and motion picture special effects.

A camera system based on this sensor can record an event with a series of images taken at a high frame rate, allowing them to be viewed at lower speeds.

Photobit say that the PB-MV40 compares favorably with CCDs in two categories: speed and price – CCDs that offer the same 4M resolution run up to only 25 fps. Secondly, CCDs of this resolution can cost three times as much – the PB-MV40 sells for less than $1,000.

In addition, the PB-MV40 makes frame rates of greater than 2,000 fps possible through partial scan.

Features include on-chip 10-bit analog-to-digital converters outputting monochrome or colour digital video in 2352H-by-1728V-pixel format, a 4:3 aspect ratio, at 0-240 fps.

The PB-MV40 is designed with a 7-micron-square active-pixel, has a digital responsivity of 2,500 bits per lux second and an architecture that provides the camera designer access to internal sensor operations.

Frame rate, integration time, windowing function, and other parameters are adjusted via a simple digital interface to suit specific applications.
