Linear Image Sensors

A linear image sensor is a solid-state device that converts an optical image into an analog signal in a line-by-line fashion. There are two types of linear image sensors with distinct circuit configurations: CMOS image sensors and CCD image sensors. Linear image sensors are suitable for applications such as copier scanning components, image scanners, barcode readers, the line scan camera used for a visual examinations (a film, printed matter, cloth, etc.),　grain color sorter, etc. and bank note recognition systems in banking terminals.

These are photos of packages housing linear image sensors.

Toshiba has long been an industry leader in the area of linear image sensors for scanning applications, delivering a multitude of products to major market segments. Toshiba will expand its portfolio of image sensors for sensing applications and is focused on the development of technologies and products applicable to a wide range of applications.

Lineup

Monochrome sensor
A Monochrome sensor has a configuration with a single photodiode row without a color filter. Suitable for position detection and monochrome imaging.
Details
Color sensor
A Color sensor has a confirguration with 3 lines of photodiode rows with a color filter (Red, Green, and Blue).
It has a color filter, so a color image can be obtained with a white light source.
