From the 1st of August, Fujitsu will begin sales of two new image-processing chips, MB91683 and MB91686, in its Milbeaut line of advanced image processing large-scale integrated circuit (LSI) chips for digital cameras.
MB91683 and MB91686 are part of the new fourth-generation line (M-4) of Fujitsu’s Milbeaut chips. The MB91683 provides features in a single chip numerous functions that are ideal for compact digital cameras, while the MB91686 in addition features video functionality. Peripherals functions are now embedded in single chip; this enables smaller camera size and lowers overall cost. Programs stored on NAND flash memory can boot system, eliminating the need for external memory to program.
The Milbeaut line of image-processing chips integrate various functions necessary for image processing – such as color interpolation, compression, and a variety of interfaces – into a single chip, thereby making it ideal for use in a variety of digital cameras and mobile phones featuring imaging functions.
The new MB91683 chip has 13mm square, and is designed for compact, slim, and lightweight digital cameras, as it provides basic functionalities required on a single chip. Functions which in the past required peripherals devices – such as audio processing, calendar features, anti-shake with high-sensitivity photography, are now featured on the chip. Integrating these functions into a single chip enables the design of smaller, lighter, and slimmer cameras featuring high-resolution imaging. MB91683’s CPU internal clock is 108 MHz (maximum), and its image-processing unit, 54 MHz.
MB91686 is based on the MB91683 model and offers additional features for video recording and playback and CD-quality audio processing. MPEG4 codec is embedded, offering both high-quality imagery and high compression rates. It also enables high-quality video recording and playback at 30 frames per second with video graphics array (VGA) (640 x 480) resolution. MB91686’s CPU internal clock is 132 MHz (maximum), and its image-processing unit, 66 MHz.
Both chip models are manufactured at Fujitsu’s leading-edge advance semiconductor fab in Mie, Japan using 300-mm wafers and 90 nanometer (nm) process technology. MB91683 will cost 3,500 yen, and MB91686 4,000 yen. Fujitsu will produce 300,000 chips/month per model.
