N3290x_Design_Guide_A1.pdf



 Capture (CMOS Sensor I/F)
  CCIR601 & CCIR656 interfaces supported for connection to CMOS image sensor
  Resolution up to 3M pixel
  YUV422 and RGB565 color format supported for data-in from CMOS sensor
  YUV422, RGB565, RGB555 and Y-only color format supported for data storing to system memory
  Planar and packet data format supported for data storing to system memory
  Image cropping supported with the cropping window up to 4096x2048
  Image scaling-down supported
  Vertical and horizontal scaling-down for preview mode supported NO.:
  The scaling factor is N/M
  Two pairs of configurable 8-bit N and 8-bit M for vertical and horizontal scaling-down
  The value of N has to equal to or less than M
  Frame rate control supported
  Combines two interlace fields to a single frame supported for data in from TV-decoder

可以接 300万像素的摄像头。

分辨率应该还受DCMI接口最大时钟影响,内存带宽有限。
300W应该只是内部DMA的可搬移范围,如果时钟比较低,那应该是可以满足300W。
