Toshiba released lens-reduction type CCD linear image sensor with low random noise that helps improve image quality in devices such as A3 multifunction printers.
Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched a lens-reduction type CCD linear image sensor “TCD2728DG” for A3 multifunction printers. The sensor has 7,500 image sensing elements (pixels) and supports A3 multifunction printers. It is also more effective at reducing random noise (NDσ) than Toshiba’s current TCD2726DG.
Business offices are seeing a growing need for high-speed, high-resolution copying and scanning of large volumes of different kinds of documents. This is particularly true for A3 multifunction printers, where improving image quality has become an important issue, and NDσ in the signal has to be suppressed to enhance image quality.
TCD2728DG has lower output amplifier gain than Toshiba’s current product, TCD2726DG, and reduces NDσ by approximately 40%. This improvement enhances image quality in multifunction printers.
The new CCD linear sensor achieves a data rate of 100 MHz (50 MHz × 2 channels), enabling high-speed processing of large volumes of images. This makes it well-suited for line scan cameras used in inspection systems that require real-time decision-making.
The company added: “Toshiba will continue to expand its product lineup to support scanning by multifunction printers and the sensing applications of inspection devices, and to meet growing demand for high-speed, high-resolution imaging and sensing technologies.”
Shipments of the new CCD linear sensor start immediately.
