The official Raspberry Pi camera module has the advantage that it doesn’t need any USB ports or GPIO pins and can be used directly via the CSI port. It is available with and without an infrared filter, which for example can be of advantage when shooting at night.

This tutorial shows how to set up, install, and take pictures or videos.

Required Hardware Parts


At the moment there are two different camera modules: the standard version and one without an infrared filter (NoIR). This makes them ideal for infrared imaging or low light applications. Otherwise, both cameras have 5 megapixels and can record 1080p videos at 30 frames per second.

* Raspberry Pi model B

* Raspberry Pi camera module

* alternatively: NoIR Raspberry Pi camera module

* if necessary, a longer ribbon cable

Setup


Except for the Raspberry Pi Zero and the Compute Model, all versions have two ports on the board: DSI (for the official touch screen) and CSI (Camera Serial Interface) for the cameras. For new models, the ports are labelled, the CSI port is closer to the USB port.

To connect the camera properly, first, you have to loosen the clipper on the Pi (best with two fingers at the same time). Then you can connect the ribbon cable. In this case, the side of the cable on which the contacts are free must be on the opposite side of the clipper (see the picture below, where the contacts are also visible).

If the length of the “ribbon cable” is not enough, there are also longer ones yor can buy.

The contact side of the ribbon cable must point “up” where the contacts of the CSI port are.

Installation


Depending on how long your operating system (Raspbian/Jessie) has not been updated, some new packages may need to be loaded:
sudo apt-get update && sudo apt-get upgrade
Then we activate the camera module by means of
sudo raspi-config
and select “Enable Camera” -> Enable.

After that, you have to restart.

Now we can record. To get general information about the parameters of the program, you can do the following:
raspistill
For example, to take a simple photo (via the console), enter the following command, which will shortly open a window (if you are connected to SSH, X server should be activated, otherwise remote would also be an option).
raspistill -o ~/img.jpg
Where -o specifies the output path + name. Of course, you can specify additional parameters, such as. -vf for the vertical flip.

To make videos, you can use the raspivid command. Again, you get all the possible options when entering the command without parameters. Here again, a name including the file ending (and if necessary the path) must be specified as well as the length of the video in milliseconds. The following example would take a 10-second video and save it in the home directory.
raspivid -t 10000 -o test_vid.h264
One more important note: the camera does not have a built-in microphone, so you should not be surprised why no sound is playing.

You can display your recorded files via the console as follows (you may still need to install the image viewer using sudo apt-get -y install fim):
fim -a img.jpg omxplayer test_vid.h264
All of these commands can also be nicely integrated into Python or Bash scripts.

The complete documentation for the camera module can be found here.

This is holographic projection of a whale. It is a photographic process that produces images, thanks to the differences between 2 laser beams. These images are projected on to a gym using a special camera. There is not a drop of water in the gym, let alone a whale.

The #DIY-Thermocam is a #do-it-yourself #infrared #camera, based on the popular FLIR Lepton long-wave-infrared array sensor. Everything, from #software to #hardware, is completely #open-source! This allows everyone to modify or extend the functionalities of the device to their own needs!

Features:
- Fast #ARM #Cortex M4 processor (240MHz), based on the popular, #Arduino compatible #Teensy 3.6
- 160 x 120 pixel FLIR Lepton3 long-wave infrared array sensor for live thermographic #images
- Frame rate of up to 9 FPS (US export compliance) over the serial connection, 5 FPS on the device itself
- 2 MP visual camera to capture optical images, that can be used in a combined image
- MLX90614 single point-infrared sensor for high-precision spot temperatures (10° FOV)
- HDMI or analog #video output capabilities (640x480 pixel) over external video output module
- 3 operating modes: thermal only, thermal + visual, video recording
- 18 different color schemes including rainbow, ironblack, grayscale, hot & cold
- 3.2 inch LCD touch #display with bright colors, wide angle and resistive touch
- Save thermal and visual images with a resolution of 640x480 pixels on the device
- Save real-time videos and interval images with different time-lapse settings
- 8GB internal storage, accessible as an exchangeable SD / microSD slot
- 2500 mAh lithium polymer battery for long operation time (4-6 hours)
- Open-source firmware written in Arduino compatible C/C++ code
- Regular #firmware #updates with new features, flashable over a standalone firmware updater
- Standalone thermal viewer application to save high-quality thermal images & videos on the computer
- Fully compatible to the comprehensive thermal analysis software #ThermoVision by Joe-C
- Use simple commands to receive all thermal & configuration data over the #USB serial port with high speed

Where are the Eyes?


 
Hi community! #Question about #smartphones: My partner needs a new phone, and it needs to: - have a good #camera - not be Apple - be #Android-based for availability of apps - works in and can be ordered from #Australia - good battery life - secure and as much #freesoftware as possible - good environmental and ethical track record

Fairphones are sadly not available here. We were looking into the #One+3 and it looks pretty good.

Wadya reckon? :) #oneplus
