takePicture rawCallback返回一个空指针。 getPictureFormat仅允许使用.jpg。虽然可以使用getParameters（）setJpegQuality（100）setParameters改进jpeg，但返回的图像仍然是jpeg。要获取位图图像需要调用BitmapFactory.decodeByteArray，这可能需要1/2秒才能处理。
我正在处理的应用程序需要相机可以生成的最详细的图像，这并不一定意味着漂亮。原始相机芯片捕获格式是拜耳。
答案 0 :(得分：10)
android（至少是我的）有2个相机参数"rawsave-mode"和"rawfname"，默认为rawsave-mode=0。通过设置rawsave-mode=1，相机将保存原始相机图像文件，并照常执行其他相机功能。
Camera.Parameters parameters=preview.camera.getParameters();
parameters.set("rawsave-mode", "1");
parameters.set("rawfname", "/mnt/sdcard/test.raw");
preview.camera.setParameters(parameters);
preview.camera.takePicture(shutterCallback, null, jpegCallback);
生成的文件的实际名称将被修改为包含正在生成的原始文件的参数。对于我的某个机器人，生成的名称为"test__1604x1206_10_2.raw"，其为a1 1604x1206图片，10bit格式为2.而"test__1284x966_10_3.raw"为1284x966图片，10 bit格式3. 10 bytes存储为2 byte short int (little endian)。
parameters.set("rawsave-mode", "2");
// setting the rawsave-mode to 2 increased the resolution to 3204x2406
// and output the file test__3204x2406_10_2.raw
图像数据大致为8 bit，但浮在10 bit内，其中较亮的图像可能使用较高的值而较暗的较低。这允许图像处理软件创建直方图并捕获图像的有用范围。由于光不是常数，因此也可能需要以不同的方式调整一个通道，以使图像看起来颜色正确。网上有很多关于色彩理论的信息，可以完全解释这一点，但是新用户要注意，10 bit到8的转换很快就会深入。如果你想要漂亮的图片，请使用android图片捕获而不是原始图片！
格式表示位的拜耳模式。 Bayer是一种格式，其中行和列的奇数/偶数值指示像素表示的颜色，其中RGB对于每个像素的每个颜色通道具有8 bit值，拜耳只有一个{{ 1}}像素值，其中一个像素为红色，然后是下一个绿色，红色，绿色，红色，绿色。然后下一行有蓝色，绿色，蓝色，绿色，蓝绿色。要确定像素的10 bit值，需要解释周围的像素。
RGB格式3的像素顺序为
Format 2 has pixel order
// 0 1 2 3 4 5
// 0 G R G R G R
// 1 B G B G B G
// 2 G R G R G R
// 3 B G B G B G
我不确定这种技术是否适用于其他机器人，或者它是否适用于未来的机器人。如果有人试图这样做，请添加成功或失败的评论。我的手机是直接中国进口解锁iHTC Android手机已根植。
