camera - QX1，手动拍摄模式（M）通过API

Question

QX1 上非常需要M（手动）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 上选择全手动曝光模式吗？

Answer 1

不，您不能使用 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（并可选择将它们显示给用户），然后在setExposureMode中使用其中一种模式。

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 将错误返回给setExposureMode调用的原因。

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

• getSupportedProperty -> 返回相机支持的属性值。
• getProperty -> 返回属性的实际值
• setProperty -> 允许为属性设置新值
• getAvailableProperty -> 返回当前值和支持的值。

这样，如果应用程序编码良好，它将支持所有相机。

因此，这不是 API 问题，而是固件问题。QX1 的当前固件不支持手动模式。

还没有官方固件更新:(

你有没有试过在这里找到：https ://github.com/erik-smit/sony-camera-api/blob/master/actEnableMethods.sh

Answer 3

看来你可以。根据此处的表格，您可以在 QX1 上设置曝光模式。您可以将setExposureModeAPI 方法与以下 JSON 类似：

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