相机 ISO 设置/快门速度 [英] Camera ISO setting/ shutter speed

问题描述

我正在寻找一种方法来改变我的 Evo 4G 摄像头的感光度.我知道这不是相机的快门速度，因为它是数码相机.下一个最相关的方面是 ISO 设置，但 Android SDK 无法操作它.有人知道替代方案吗?即场景模式、曝光或效果

I am looking for a way to change the light sensitivity of my Evo 4G camerea. I know it is not the camera's shutter speed because it is a digital camera. The next most relevant aspect is the ISO setting, but the Android SDK does not have a way to manipulate it. Does any one know an alternative? i.e scene mode, exposure or effects

**parameter.set("iso", int) 设置iso.

**parameter.set("iso", int) sets the iso.

有人知道场景模式值代表什么吗?

Does anyone have the run down on what scene mode values represents?

感谢您的意见.我已经多次查看这些页面.我一直在寻找类似于 parameter.set("iso", int) 的函数，因为该函数成功地更改了 iso 设置.相机没有光圈作为设置.也许我可以操作一些固件文件.

Thanks for the input. I have looked over those pages numerous times. I was looking for a function similar to parameter.set("iso", int) because this function was successful in changing the iso setting. The camera does not have aperture as a setting. Maybe I can manipulate some firmware files.

Sorry it's late but might be helpful for others

设置光圈:

Camera.Parameters params = camera.getParameters(); 
params.set("mode", "m");
params.set("aperture", "28"); //can be 28 32 35 40 45 50 56 63 71 80 on default zoom
params.set("shutter-speed", 9); // depends on camera, eg. 1 means longest
params.set("iso", 200);
