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.
“TCD2569BFG” offers high image quality with less color registration by reducing the spacing between pixel arrays (red-green, green-blue). A built-in sample and hold circuit lengthens the video output signal period of the sensor and contributes to easier design of high speed scanners for use in office automation equipment and industrial equipment. On top of this, 4-volt saturation output voltage in the CCD shift register reduces blooming. Installing a clipping function ensures the output signal voltage is held below 1.8 volts, which prevents output signal voltage from exceeding the maximum input voltage range of the analog front-end IC.
* 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
