Toshiba Launches Lens Reduction Type, 5340-Pixel by 3-line Linear Image Sensor
Toshiba Electronic Devices & Storage Corporation has introduced the “TCD2569BFG,” a lens reduction type, 5340-pixel by 3-line color CCD linear image sensor for office automation and industrial equipment that realizes 24 lines per millimeter resolution for an A4-size document.
More and more users want A4-size multifunction printers that can deliver the same high image quality and high speed operation as A3-size models, especially for scanning objects other than documents, three-dimensional objects with very high reflectance and shiny objects. Scanning these objects with conventional lens reduction type CCD linear image sensors often results in blooming of the sensor and horizontally streaked images—and the output signal voltage of the sensor in the blooming area often exceeds the maximum input voltage range of the analog front-end IC.
The Key Features of the Toshiba TCD2569BFG include:
- 2-line spacing between pixel arrays (red-green, green-blue)
- Longer video output signal period with built-in sample and hold circuit
- Maximum output signal voltage of 1.8 volts with clipping function
The Major Application include:
- A4-size multifunction printers,
- image scanners
- input devices for measuring equipment
- color sorting machine
Mass production shipments start today.
