7.1.1 Capture pictures via USB port
When a USB flash drive is plugged into the USB port and icon showed up to illustrate the drive is
ready, user can snap shot or capture the picture showed on the LCD and save it into the flash disk.
Here are the procedures: When the USB flash disk device is ready, whether the video phone is in cam-
era local loopback mode or in a live video call, just press “OK” button once, the LCD will freeze 1 or 2
seconds, the captured picture will be saved in the disk using a format like: “gxv_xxxx.yuv”.
Only one picture can be saved at one time.
User needs special decoding software to see the captured pictures stored in the USB flash disk. A free
software called XnView can be downloaded from:

Once this software installed, please choose file type “YUV - YUV 4:2:2” to open and see the captured
pictures.
