PiCam - UI for portable Raspberry Pi Camera

SCRIPT IS FUNCTIONAL BUT NOT FINISHED YET!

This Script makes a basic UI for controlling and viewing Camera settings. Images can be viewed with feh.

It is verry likely that you'll have to make changes in the code to make it work for your hardware and needs. For example:

• Screen and Preview resolution

wscreen  = 800 #Screen width
hscreen  = 480 #Screen height
wpreview = 640 #Preview width (https://andrew.hedges.name/experiments/aspect_ratio/)
wmenu    = 100 #Menu with (left)

• Font size (adjust if you changed some of the above)

#                                                                               Font size
#                                                                                  ▼▼
button_ISO = Menu.button(xdistl, ydist + button_dist*0, button_w, button_h, "ISO", 26, button_ISO_pressed, True)
button_SS  = Menu.button(xdistl, ydist + button_dist*1, button_w, button_h,  "SS", 26,  button_SS_pressed, True)
button_AWB = Menu.button(xdistl, ydist + button_dist*2, button_w, button_h, "AWB", 26, button_AWB_pressed, True)
button_EXP = Menu.button(xdistl, ydist + button_dist*3, button_w, button_h, "EXP", 26, button_EXP_pressed, True)
button_ETC = Menu.button(xdistl,  h - ydist - button_h, button_w, button_h,   "⚙", 30, button_ETC_pressed, True)

• Default settings

#Output settings
setting_output_location = "/home/pi/Pictures" #Where to store pictures
setting_output_prefix = "FCM_"   #Filename prefix
setting_output_suffix_noraw = "" #Filename suffix when RAW disabled
setting_output_suffix_raw = "R"  #Filename suffix when RAW enabled
setting_encoding = "jpg"         #Encoding of picture taken
setting_mode = 3                 #Sensor mode
setting_quality = 90             #Compression quality
setting_thumbnail = "64,48,35" #Thumbnail settings ("width,height,quality")


#Default Camera settings
setting_ISO = 0        #ISO
setting_AWB = "auto"   #Auto White Balance
setting_SS  = 0        #Shutter Speed
setting_EXP = "auto"   #Exposure Mode
setting_EXM = "matrix" #Exposure Metering
#Default additional settings
setting_FoM     = False  #Display focus FoM value
setting_raw     = False  #Add raw Bayer data to JPEG
setting_flicker = "50hz" #Flicker avoidance
setting_hf      = False  #Flip Image horizontally
setting_vf      = False  #Flip Image vertically
#Default advanced settings
setting_USB  = True
setting_HDMI = True
setting_WiFi = True
setting_SSH  = True
setting_VNC  = True

#Artist
setting_photographer = "YOUR NAME HERE" #Name of photographer (for EXIF Artist)





#Other
title = "PiCam"
cursor_hidden = True
style = "line-keys" #How the UI looks. You can use "boxes", "line", "line-keys" or "line-touch"
debugging = False #Debugging (print stuff to console)

• Hardware integration:
  • GPIO Pins

#GPIO Buttons
#If you use buttons connected to GPIO, you can set the pin numbers here:
button_capture = Button(5) #Take a photo
button_up      = Button(13) #Move up in menu
button_select  = Button(26) #Select in menu
button_down    = Button(19) #Move down in menu

• Battery and RTC

#Hardware
hw_battery = False #Enable battery. You have change the "battery()" function yourself if you use something different than a pisugar: https://github.com/PiSugar/PiSugar/wiki/PiSugar-Power-Manager-(Software)
hw_utc = False #Enable UTC. You have change the "utc()" function yourself if you use something different than a pisugar: https://github.com/PiSugar/PiSugar/wiki/PiSugar-Power-Manager-(Software)

def battery(): #Get battery level in %
    if hw_battery:
        battery = os.popen("echo get battery | netcat -q 0 127.0.0.1 8423 | sed s/[^0-9.]*//g").read()
        battery = battery.split(".")[0].strip() + "%"
        return battery
    else:
        return "N/A"

def utc(): #Set System time from UTC and update time from internet if connected
    time = 300
    Timer(time, utc).start() #Run function periodically
    os.system("echo rtc_web | netcat -q 0 127.0.0.1 8423 > /dev/null 2>&1 &")
    os.system("sleep 5 && echo rtc_rtc2pi | netcat -q 0 127.0.0.1 8423 > /dev/null &")

Hardware I personally use:

• Raspberry Pi 4 Model B: https://www.raspberrypi.org/products/raspberry-pi-4-model-b/
• Raspberry Pi HQ Camera: https://www.raspberrypi.org/products/raspberry-pi-high-quality-camera/

And of course:

• C & CS Mount lenses
• Some generic push-buttons
• A case thet I 3D printed
  • Screws & Glue
