Camera2 api 预览与捕获不同

Question

我正在使用 camera2Basic example 并且我修复了曝光时间、iso、白平衡等

mPreviewBuilder.set(CaptureRequest.CONTROL_AF_MODE,CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTURE);

//mPreviewBuilder.set(CaptureRequest.LENS_FOCUS_DISTANCE, DEFAULT_FOCUS_DISTANCE);

mPreviewBuilder.set(CaptureRequest.CONTROL_AE_MODE, CameraMetadata.CONTROL_AE_MODE_OFF);

mPreviewBuilder.set(CaptureRequest.NOISE_REDUCTION_MODE, CameraMetadata.NOISE_REDUCTION_MODE_FAST);
mPreviewBuilder.set(CaptureRequest.EDGE_MODE, CameraMetadata.EDGE_MODE_FAST);
mPreviewBuilder.set(CaptureRequest.CONTROL_AE_PRECAPTURE_TRIGGER, CaptureRequest.CONTROL_AE_PRECAPTURE_TRIGGER_CANCEL);

mPreviewBuilder.set(CaptureRequest.CONTROL_AWB_MODE, wbMode);
mPreviewBuilder.set(CaptureRequest.CONTROL_AWB_LOCK, wbLock);

mPreviewBuilder.set(CaptureRequest.SENSOR_SENSITIVITY, isoValue);
mPreviewBuilder.set(CaptureRequest.SENSOR_EXPOSURE_TIME, exposureValue);

我通过旋转我的 phone 来拼接几个 photos。拍照的时候preview looks还好，但是拍出来的亮度就完全不一样了

当我检查图像 exif 数据时，它们具有相同的曝光时间和 iso（不在 Nexus 上）

我不知道我错过了什么。有什么建议为什么会发生吗？谢谢

我的问题是没有正确使用 session.setRepeatingRequest() 和 session.capture()。请检查
