The Moon: Raspberry Pi HQ Camera + Tamron SP 500mm f8 Mirror Lens

This photo and video was token using Raspberry Pi HQ Camera + Tamron Adaptall-2 SP 500mm f8 (55BB).


using Nikon-C adapter






In my usage scenario: The Raspberry Pi 4B/8G is installed with HQ Camera Module (mount with manual focus lens). Remote control with Android with xrdp/Microsoft Remote Desktop. Such that I can control and change setting on remote Android device running Python code, adjust focus/aperture on the lens, and check the effect on local HDMI preview at real-time.

rpiCam_20210619a.py, to capture still photo.

min. version of RPi/Python Code to control Camera Module with preview on local HDMI

It's a minimum version of my another exercise "RPi/Python Code to control Camera Module with preview on local HDMI"; with minimum functions preview and capture only, using PyQt5 GUI, fixed resolution 240x240, and display the captured image on GUI. You can also choice save file name; image.jpg or img_<timestamp>.jpg, under Desktop folder. It's used to prepare images for my coming exercise "Raspberry Pi/Python send image to ESP32/MicroPython via WiFi TCP socket".

In my usage scenario: The Raspberry Pi 4B/8G is installed with HQ Camera Module (mount with manual focus lens) and a 4 inch HDMI IPS Touch Display. Remote control with Android with xrdp/Microsoft Remote Desktop. Such that I can control camera on remote Android device, adjust focus/aperture on the lens, and check the effect on local HDMI preview at real-time.

RPi/Python Code to control Camera Module with preview on local HDMI

It's a Python3 code run on Raspberry Pi to control Camera Module with various setting. The preview display on local HDMI. 


In my usage scenario: The Raspberry Pi 4B/8G is installed with HQ Camera Module (mount with manual focus lens) and a 4 inch HDMI IPS Touch Display. Remote control with Android with xrdp/Microsoft Remote Desktop. Such that I can control and change setting on remote Android device, adjust focus/aperture on the lens, and check the effect on local HDMI preview at real-time.

It's a long time ago, I make a similar code with preview stream video, both control and preview on remote desktop, Python to capture image from Pi Camera Module, with image effects. But I'm not satisfied by the delay of stream video, that's why I re-develop this code again.


The lens shown on the video is a Nikkor ais 28mm f2.8 manual focus lens, connected to HQ Camera Module via a Nikon F to C mount adapter.

#==========================================================
root.mainloop()

print("- bye -")
Remark:
As this is writing, picamera is still 1.13, so the maximum resolution is 3280x2464 for V2, not HQ. 


~ Another minimum version:  with minimum functions preview and capture only, using PyQt5 GUI, fixed resolution 240x240, and display the captured image on GUI. You can also choice save file name; image.jpg or img_<timestamp>.jpg, under Desktop folder.

Python to control Raspberry Pi Camera

It's a simple Python script run on Raspberry Pi/Raspbian to perform simple control of camera, start preview, stop preview, and capture photo.

It run with Python3.

import sys
from tkinter import *
import picamera
from pkg_resources import require
import time

#event callback functions
def evStartPreviewBtnPressed():
    print("Start Preview")
    camera.start_preview()

def evStopPreviewBtnPressed():
    print("Stop Preview")
    camera.stop_preview()

def evCaptureBtnPressed():
    print("Capture")
    timeStamp = time.strftime("%Y%m%d-%H%M%S")
    targetPath="/home/pi/Desktop/img_"+timeStamp+".jpg"
    print(targetPath)
    camera.capture(targetPath)

print(sys.version)
print(require('picamera'))


#Prepare camera
camera = picamera.PiCamera()


root = Tk()
root.geometry("600x360")
root.wm_title("Hello")
#root.configure(bg = "#909090")

labelSys = Label(root, text=sys.version, justify=LEFT)
labelSys.grid(row=0, columnspan=2, sticky=W)
labelPiCameraVer = Label(root, text=require('picamera'), justify=LEFT)
labelPiCameraVer.grid(row=1, columnspan=2, sticky=W)
                         

btnStartPreview = Button(root, text="Start Preview",
                         command=evStartPreviewBtnPressed)
btnStopPreview = Button(root, text="Stop Preview",
                        command=evStopPreviewBtnPressed)
btnStartPreview.grid(row=2, column=0, sticky=W+E)
btnStopPreview.grid(row=2, column=1, sticky=W+E)

btnCapture = Button(root, text="Capture",
                    command=evCaptureBtnPressed)
btnCapture.grid(row=3, columnspan=2, sticky=W+E)


root.mainloop()

#close tasks
camera.close()

With Microsoft's Remote Desktop on Android device, it can be run remotely. The camera preview will be displayed on local screen.


xredp have to be installed in Raspberry Pi, with command:
$ sudo apt-get install xrdp

This video show how it run on Raspberry Pi 3 with Waveshare 4" HDMI LCD, run it on Android phone with Remote Desktop app. The local mounted display (4" HDMI LCD) is used as viewfinder.


Remark:
If you run the script locally, the preview will cover the GUI, but you can still click on it. Click the original position of the Stop Preview button to close the preview.

NOT WORK on High Quality Camera

Once I received High Quality Camera and tested on it, the script fail when capture continuously. Then I make a simple script to take photos using RPi Camera Module, work on v2.1, but also faile on High Quality Camera with "picamera.exc.PiCameraRuntimeError: No data received from sensor."


What's wrong on the script? or my Raspberry Pi High Quality Camera defected?

Tested on:
- Raspberry Pi 3B+
- Update Raspberry Pi OS
- Python 3.7.3
- picamera 1.13

doCappp.py 
import picamera
import time

with picamera.PiCamera() as camera:
    camera.start_preview()
    for i in range(5):
        camera.resolution = (1280, 720)
        time.sleep(1)
        filename = 'imageA%02d.jpg' % i
        camera.capture(filename)
        print('Captured %s' % filename)
    time.sleep(7)
    
    print("End")
    camera.stop_preview()
    time.sleep(1)
    print("End End")
    camera.close()
    print("End End End")
