NEC Electronics has released the uPD9281GC as part of its NeoClearResolution super-resolution ASSP (application-specific standard product) lineup. The ASSP addresses the divergence between image resolution and the high resolution of AV (audio-visual) display systems, and supports the LVDS (low-voltage differential signalling) interface, a technology adopted in broad ranges of flat panel displays, projectors for digital TVs and PC monitors.
For the more advanced models of flat panel displays and projectors, higher screen resolution is essential to the specification of products with high display quality. NEC Electronics and NEC Central Research Laboratories jointly developed a technology that enables high-resolution processing with one frame of image data.
The new ASSP supports the LVDS flat panel display interface with an integrated LVDS-interface circuit that connects the flat panel display and the image data processing circuits. The ASSP reduces external components, saves space on system boards, and reduces "mosquito noise" caused by JPEG and MPEG compressed images. The ASSP integrates a noise-reduction feature to reduce mosquito noise unique to compressed video images of MPEG2, widely used for digital media such as DVDs and Blu-ray discs, and H.264 used for viewing digital satellite broadcasting.
The ASSP also reduces mosquito noise for JPEG compressed images used especially for digital still cameras. Reducing the mosquito noise enables processing of images that are more natural. The ASSP can be used to select area to apply super-resolution. Designers can select up to four specific sections of an image and apply the company's super-resolution technology to enhance image quality of those sections. This feature enables the application of the super-resolution technology, such as applying the technology onto a specific area of the picture-in-picture display, which is useful for picture-enhancement demonstrations at consumer electronic stores.
