說明

The DM355 is a highly integrated, programmable platform for digital still camera, digital photo frames, IP security cameras, 4-channel digital video recorders, video door bell application, and other low cost portable digital video applications. Designed to offer portable video designers and manufacturers the ability to produce affordable portable digital video solutions with high picture quality, the DM355 combines high performance MPEG4 HD (720p) codecs and JPEG codecs up to 50M pixels per second, high quality, and low power consumption at a very low price point. The DM355 also enables seamless interface to most additional external devices required for a complete digital camera implementation. The interface is flexible enough to support various types of CCD and CMOS sensors, signal conditioning circuits, power management, DDR/mDDR memory, SRAM, NAND, shutter, Iris and auto-focus motor controls, etc.
