Toshiba Electronics has unveiled the TCD2728DG: an advanced lens reduction type CCD lineage image sensor specifically designed for A3 multi-function printers.
This solution significantly improves upon Toshiba’s existing TCD2726DG by achieving an approximate 40% reduction in random noise (NDσ). This key 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 occur 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, therefore 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 multi-function printers. Beyond printers, its capabilities extend to other inspection devices, such as 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.
