需安装：jpegoptim

```sh
#!/bin/bash

# 预处理目录
pre_dir=/mnt/sda/cam/pre
# 最终保存目录
dir=/mnt/sda/cam

mkdir $pre_dir 2&>1 > /dev/null
mkdir $dir 2&>1 > /dev/null

# 【可选】上报电池信息，用于自动化充电
# adb shell dumpsys battery | grep -E 'level|AC' |
#     sed ':a;N;s/\n/,/g;ta' - |
#     sed 's/AC powered/AC/g' - |
#     sed 's/ //g' - |
#     sed 's/,/,"/g' - |
#     sed 's/:/":/g' - |
#     sed 's/^|&/"/g' - |
#     sed 's/^/{"/g' - |
#     sed 's/$/}/g' - |
#     xargs -I value -o mosquitto_pub -t 'phone/battery/level' -h 192.168.31.110 -p 9883 -m 'value'

adb shell input keyevent 26
sleep 0.5
adb shell am start -a android.media.action.STILL_IMAGE_CAMERA
sleep 0.5
adb shell input tap 539 900
sleep 1
adb shell input keyevent 27
sleep 1
adb shell input keyevent 4
adb shell input keyevent 26

adb shell find /sdcard/DCIM/Camera -name "*.jpg" | xargs -o -I path adb pull path $pre_dir
adb shell rm /sdcard/DCIM/Camera/*

# 【可选】压缩图片，修改size可控制图片大小
find $pre_dir -name "*.jpg" | xargs jpegoptim --size=500k

mv $pre_dir/* $dir
```

python3版本：

添加了对屏幕是否亮屏的检测

```python
#!/bin/python3
