摄像头是天敏的minicom，硬件像素30万，插值像素48万。最大分辨率640x480.
安装驱动的过程如下：
软件包是spca5xx-source。这是 source for the spca5xx driver。apt-get 安装以后，在/usr/src/下面有驱动的源码包。解压后
[root@localhost spca5xx-20060501]# make
[root@localhost spca5xx-20060501]# make install
[root@localhost spca5xx-20060501]# modprobe spca5xx
看看驱动模块挂载好了没有?
[root@localhost spca5xx-20060501]# lsmod |grep spca5xx
spca5xx 659920 0
videodev 7040 1 spca5xx
我们再查看一下设备/dev/video0是否存在?
[root@localhost spca5xx-20060501]# ls -lh /dev/video0
crw------- 1 beinan root 81, 0 06-08 09:33 /dev/video0
还可以这样查看硬件信息：
root@etch:~$ lshal | grep video4linux
udi = '/org/freedesktop/Hal/devices/usb_device_ac8_303b_noserial_video4linux'
info.udi = '/org/freedesktop/Hal/devices/usb_device_ac8_303b_noserial_video4linux' (string)
linux.subsystem = 'video4linux' (string)
video4linux.device = '/dev/video0' (string)
info.capabilities = {'video4linux'} (string list)
info.category = 'video4linux' (string)
linux.sysfs_path = '/sys/class/video4linux/video0' (string)
root@etch:~$ lshal -l -u usb_device_ac8_303b_noserial
udi = '/org/freedesktop/Hal/devices/usb_device_ac8_303b_noserial'
info.udi = '/org/freedesktop/Hal/devices/usb_device_ac8_303b_noserial' (string)
linux.subsystem = 'usb' (string)
linux.hotplug_type = 1 (0x1) (int)
usb_device.bus_number = 2 (0x2) (int)
usb_device.can_wake_up = false (bool)
usb_device.is_self_powered = false (bool)
usb_device.version_bcd = 272 (0x110) (int)
usb_device.speed_bcd = 4608 (0x1200) (int)
usb_device.linux.device_number = 5 (0x5) (int)
usb_device.num_ports = 0 (0x0) (int)
usb_device.max_power = 160 (0xa0) (int)
usb_device.device_revision_bcd = 256 (0x100) (int)
info.product = 'PC Camera' (string)
usb_device.product = 'PC Camera' (string)
info.vendor = 'Vimicro Corp.' (string)
usb_device.vendor = 'Vimicro Corp.' (string)
usb_device.product_id = 12347 (0x303b) (int)
usb_device.vendor_id = 2760 (0xac8) (int)
usb_device.device_protocol = 0 (0x0) (int)
usb_device.device_subclass = 0 (0x0) (int)
usb_device.device_class = 255 (0xff) (int)
usb_device.num_configurations = 1 (0x1) (int)
usb_device.linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2' (string)
info.linux.driver = 'usb' (string)
info.bus = 'usb_device' (string)
info.parent = '/org/freedesktop/Hal/devices/usb_device_0_0_0000_00_1d_1' (string)
linux.sysfs_path_device = '/sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2' (string)
linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2' (string)
然后，可以安装应用软件。
软件1：gqcam
可以用apt-get来安装。运行命令如下：
root@etch:~$ gqcam -v /dev/video0
这个东西的界面很大，几乎占了半个屏幕。不好用。
软件2：camstream
可以用apt-get来安装。还可以安装说明文档camstream-doc。
运行命令是：
root@etch:~$ camstream
可以自己添加菜单项来运行它。
软件3：SpcaView 软件包，包括一组工具
这个东西我只是听说。没有用过。
