Toshiba introduces lens reduction type CCD linear image sensor for A3 multifunction printers

August 14th 2025

Toshiba Electronics Europe GmbH (“Toshiba”) introduces the TCD2728DG, an advanced lens reduction type CCD linear image sensor specifically designed for A3 multifunction printers. This product significantly improves upon Toshiba’s existing TCD2726DG by achieving an approximate 40% reduction in random noise (NDσ). This crucial enhancement, which stems from reducing the output amplifier gain, directly improves the image quality in multifunction printers, addressing the impact of irregular noise that affects image quality.

The TCD2728DG features a high-speed CCD linear image sensor with a maximum data rate of 100MHz (primary clock frequency 50MHz × 2 channels). To mitigate electromagnetic interference (EMI) that can arise with increased operational speed, the sensor incorporates a built-in timing generator and a CCD driver. These devices not only generate the necessary signals to drive the linear image sensor but also substantially reduce the number of required CCD drive terminals, thereby simplifying system development and integration.

Featuring a three-line configuration with 7500 pixels for each red, green, and blue colour filter, the TCD2728DG is well-suited for A3 multifunction printers. Beyond printers, its capabilities extend to various inspection devices, including semiconductor inspection equipment and food sorting equipment. Toshiba is committed to continuously expanding its product lineup to support advanced scanning functions in multifunction printers and diverse sensing applications.
