Question

非常需要 M （手动）QX1上的曝光模式。我正在寻找我的问题的答案，但没有找到确切的答案。我可以通过API在QX1上选择完整的手动曝光模式吗？

Answer 1

不，您无法使用QX1相机上的当前固件设置手动模式。

您应该使用 getAvailableExposureMode 或 getSupportedExposureMode API方法来检索支持的模式（并可选择将其显示给用户），然后使用其中一种模式在 setExposureMode 。

但是QX1相机不支持手动模式，因此getSupported / Available方法不会返回它，这就是API将错误返回到 setExposureMode 调用的原因

该API旨在支持多种具有多种不同功能的SONY相机。对于每个属性，您都有以下API方法：

getSupportedProperty - ＆gt;返回摄像头支持的属性值。
getProperty - ＆gt;返回属性的实际值
setProperty - ＆gt;允许为属性设置新值
getAvailableProperty - ＆gt;返回当前值和支持的值。

这样，如果应用程序编码良好，它将支持所有摄像头。

因此，它不是API问题，而是固件问题。 QX1的当前固件不支持手动模式。

您是否尝试过此处：https://github.com/erik-smit/sony-camera-api/blob/master/actEnableMethods.sh

Answer 3

看来你可以。根据表格here，您可以在QX1上设置曝光模式。您可以将setExposureMode API方法与以下JSON一起使用：

{
    "method": "setExposureMode",
    "params": ["Manual"],
    "id": 1,
    "version": "1.0"
}
