camera Zoom changed

念茜 2011-05-13 03:56:08
希望研究过camera的高手指点下，下面是我从zoom 1倍 smoothzoom拖到 8倍的log
在你看来这里有问题么？逻辑问题？可能出在哪里




V/camera  (30714): Zoom changed: value=1. stopped=true

D/camera  (30714):  ^_^ ZOOM_STOPPING

V/camera  (30714): Zoom changed: value=2. stopped=true

zoom change 发出的值可能和控件有关，如果控件发出的消息需要处理函数处理，在处理函数没有及时结束时消息是不正确的，这很正常。我觉得应该给处理函数加适当的同步机制，检查控件发出的消息是否正常。
i2c这种并联总线，串扰可能性非常大，如果每次启动都挂那就是错误，只有一定几率出现的才叫bug。建议将当个设备拆下来，检测重启N次是否正常

我的英文不怎么好 看得懂写不流利
我有考虑若还没有头绪 就去google group android-developers stackoverflow 等等去试试了 还得写篇英语作文-。- 对于我来说 这个工作量不比解bug小

引用 36 楼 yiyaaixuexi 的回复:

不如我这样问：
我调节从 zoom 1倍到8倍并不终止任务，而是拖着smoothzoom又回到1倍。犹豫preview速率与用户拖动调焦的速率不一致，比如我已经在调1了，它没有跑完一个过程的8，这个过程的touch的事件怎么分析。
是根据我的目标值随即就回1，还是继续到8的任务？

如果是消息队列的处理机制的话，那就会继续到8的任务，……

我怎么知道是不是消息队列的处理的呢

I2C挂了，试一下检查sensor上电时序，再有查一下同一路的I2C设备是否有过载，可以试着去掉设备看看。
[/Quote]


关掉了 G-sensor 和I2C上有可能干扰的其他设备，I2C不会挂了，这个问题已经解决。
但是zoom的stop的标志位还是错乱的，不和逻辑的。这个标致是从底层读取的，我不能人为强行赋值。

This is a fork from Google's CameraView. Based on the original one, the following has been done (As per Version 0.9.4): Resolved some bugs Implemented zoom feature (Configurable since v0.9.5) Improved API friendliness Changed return image from byte[] to Bitmap, with rotation d

camera缩放倍数频率修改
前面计算公式的distanceRatio就是这个mDistanceRatio，所以distanceRatio = 0.08；mSettingDevice2Requester.createAndChangeRepeatingRequest()——如此，调用到的camera的api2的接口函数，看名字可知该方法应该是去create和有changed时repeating请求的方法，这应该就是camera缩放倍率显示效果的函数；发现camera缩放倍率=1.0x的时候，zoomRatio = 1.0；
