Programmable Motorized Focus Camera Raspberry Pi now Support Auto Focus

Featured

Introduction

The standard pi camera is fixed focus lens, some of them are glued which can not be adjust by users, and some of them are not glued which can be adjust the lens focus manually. But in certian circumstance, you want to programmably control the focus distance remotely where the device can not be reached. The ArduCAM team now designed motorized control focus 5MP and 8MP camera module for Raspberry Pi series boards to address this problem. Now the auto focus function is also implement by the Arducam team, now the auto-focus demo source code is available on our github.

Arducam V2.1 Multi-Camera Adapter Board for Raspberry Pi 8MP Camera IMX219

Featured

Introduction

Since the old multi-camera adapter board doesn’t work with Raspberry Pi 8MP IMX219 pi camera due to the camera driver issue. Now Arducam team designed upgrade V2.1 multi-camera adapter board for both 5MP and 8MP pi cameras. Consider that the high speed CSI camera MIPI signal integrity is sensitive to long cable connection, the new adapter board can only connect maximum 4 cameras to a single pi board. Because it covers the most of the use cases like 360 degree view photography and surveillance, and add more cameras will degrade the performance of the cameras. Like always please note that Raspberry Pi multi camera adapter board is nascent product that may have some stability issues and limitations because of the cable’s signal integrity and RPi’s closed source video core libraries, so use it on your own risk.

Application

  • IoT cameras
  • Robot cameras
  • Wildlife cameras
  • 3D scanner
  • 360 view surveillance camera

Features

  • Accommodate 4  Raspberry Pi cameras on an multi camera adapter board
  • Take still photos in sequence (not at the same time)
  • Display real time video in lower frame rate
  • 3 GPIOs required for multiplexing on the adapter board
  • All camera ports are FFC (flexible flat cable) connectors
  • Support 5MP OV5647 and 8MP IMX219 pi cameras

ArduCAM NOIR Raspberry Pi camera with Motorized IR Cut Filter

Featured

Background

Raspberry pi camera has both color version pi camera board and NoIR version pi camera board. So let’s take a look at the difference between these two types of camera. The color version pi camera has 650nm IR cut filter on top of the sensor, so it can only sensitive to visible light like human eyes. While the NoIR version pi camera also called IR filter removed pi camera which doesn’t have 650nm IR cut filter on top of the sensor, and can sensitive all spectrum of light including ultraviolet light and near infrared light which cannot be seen by humans. So people will think NoIR pi camera is better than the standard color pi camera, because it is sensitive to all spectrum rather than visible light. Yes, it is good, but it depends. The problem of this effect is that the color reproduction is drastically affected.
Unlike your eyes, camera sensors can detect “near infrared” light that just outside the range of the human eye. The image below shows the result.

The plants in this view reflect more infrared than green light so they appear pink in daylight.
To make the image more akin to what humans can see, most cameras are fitted with an infrared-cut filter which only allows visible light to pass through, reflecting unwanted infrared. This is where standard color version pi camera used for.

Motorized (Switchable) infrared-cut filters

There are some instances where capturing infrared light is an advantage. In low-light conditions, cameras capture as much light as possible to produce brighter images, regardless of color. For this reason, some entry-level night-vision cameras don’t feature a cut filter, instead capturing infrared light from on-board LEDs at night at the expense of true color reproduction during the daytime.
The optimum solution is to use a switchable infrared-cut filter. In daylight, the filter covers the sensor to provide color footage, while at night the filter opens for a brighter image. In industry terms, these cameras are known as day/night or true day/night cameras.
These cameras can be combined with infrared lamps which are much more discreet than conventional white-light lighting, since the light produced can’t be seen by the human eye.

Solution

Sometimes you need the camera to work on both daylight and dark (night time) conditions, like the IP-based security camera. ArduCAM pi cameras now feature a motorized IR-cut filter on NoIR pi camera board, the IR-cut can be switched on in the daylight and can be switched off at night, and cooperated with IR light source for night vision. The highlight of this motorized IR-cut mechanism is no additional cable needed between the Raspberry Pi board and camera board.

ArduCAM pi camera with motorized IR cut filter

First we have to edit the config.txt file

sudo nano /boot/config.txt

Add this line at the end of the config.txt file, save and reboot.

disable_camera_led=1

Then use our provide python script to take normal image with IR-cut on and night vision image with IR-cut off. Using the following commands there are two pictures captured.

cd piCamLed
sudo python ./RPI_camera_IR_CUT_NOIR.py
sudo python ./RPI_camera_IR_CUT_IR.py

Introduction
ArduCAM series camera shield is a universal camera control board for Arduino. It hides the complex nature of the camera and provides the plug and play camera control interface as well as the ready to use software source code library and demo code. User can make it works in minutes without writing a line of code. The ArduCAM supports variety camera modules from 0.3MP to 5MP with different format like RAW, RGB, YUV, JPEG and can be well mated with standard Arduino boards.
ArduCAM Shield V2 and ArduCAM-Mini-5MP-Plus are the second generation of ArduCAM products, they offers the improved performance and enhanced functions than the previous revisions. They not only can capture decent 5MP JPEG images, but also can do 5MP full resolution RAW image capture, which makes it to be the ideal solution for IoT and scientific image processing applications. Even more they can record short movie clips as well.
The ArduCAM is straightforward enough that it can be easily used with an Arduino, however this simple interface means that the ArduCAM is equally easily integrated with other single board computers such as the Raspberry Pi and the Beaglebone black. It isn’t just a camera for the Arduino, it’s a camera that because it can be easily interfaced to an Arduino, can be easily interfaced to any single board computer, either directly, or through an Arduino if needed for a larger system without exposed SPI/I2C busses. In short, the ArduCAM brings a plug and play solution to digital cameras at the hardware level.

24 x 24mm Coin Size Raspberry Pi Compatible Board

Featured

ArduCAM team now is developing a coin size Raspberry Pi compatible compute module. The total size of the SOM is 24mm x 24mm, compared to the offical Raspberry Pi compute module and new Pi ZERO, it will be the smallest Raspberry Pi compatible module in the world. The coin size pi compute module is fully customizable and can offer the extra features that wasn’t provided by the standard Raspberry Pi boards. User can run the system on a small 36mm x 36mm adapter mother board with camera support. It is ideal for battery powered portable device lilke smart watch, action camera etc. The highlight feature of this coin size pi module, it supports dual camera interface and stereo vision which can be used in robots for machine vision applications or high definition drone camera. Contact us for more information about customization. Note it is not a replacement for Raspberry Pi boards, just a supplement for Raspberry Pi ecosystem and Raspberry Pi is a trademark of the Raspberry Pi Foundation. (This post made Raspberry Pi engineer and forum moderator very upset and they said that it will would breach the bootloader license. But thanks to Kristina Brooks work on an open source bootloader for Raspberry Pi, released under BSD and GPLv2+, and not including any “Raspberry Pi only” conditions, although it is a “poor” alternate at the time being, and a lot of fans build bare metal firmware.  said it could also end up being killed and will never see the light of day, just as what happened to ODROID-W board, but they can’t kill the spirit of hacking just for funs and keep us away from building something new. Once again I have to emphasize that it is not a replacement of Raspberry Pi boards, please order pi boards from Pi foundation. Our SOM maybe double or even triple price than standard pi boards, so this SOM is only available for someone who really need it and NDA required.)
