攝像頭控制器芯片MV3018工作原理:MV3018 is a Camera Control Processor providing the most efficient camera functions for portable terminal devices such as mobile
handsets. MV3018 provides rich video functions up to 30-frame display with minimized tasks in the handset main processor as well as
hardware based real-time JPEG compression and decompression. MV3018 directly transmits and previews the RGB data to the LCD
graphic memory by processing the sensor output data according to the cell phone’s command. MV3018 can allow the host processor to
download with scalable sized compressed data. In addition, MV3018 can download the compressed image to either store the original RGB
data or transfer the image to the LCD. This feature allows the main processor to minimize its function while obtaining the result of the image
process. MV3018 can support sensors up to 300K pixels with 1Mbit internal memory.
MV3018 utilizes 16-bit/18-bit data bus for communication with the main processor, including bus interface types such as Intel 80series,
Motorola 68 series, TI and AGERE base band chipsets. MV3018 provides features such as capturing and previewing 90, 180, 270-degree
images, which enables developers to be free from limitation of PCB design layout due to mechanical reasons by positioning sensors to fit
the design space. EZ-OSD technology provides Picture-in-Picture (a variable size window with overlay functions) and dynamic menu display
during image previewing. EZ-OSD allows the main processor to access OSD memory during MV3018 is in camera preview mode.
MV3018 is integrated with a hardware 2D graphic Acceleration Engine for gaming application. MV3018 provides precise power control
states, from standby state to full operation state.
