Motion blur can cause the industrial camera to capture unsharp / blurry images. Unsharp images result in inaccurate measurements, bad fault detection or wrong classifications. Motion blur is caused by movement or vibration during the exposure time of the industrial camera . When the object moves for more than 0.5 pixel during the exposure time, the image will have motion blur. To avoid motion blur, the shutter speed must freeze the scene, so the object does not move more than 0.5 pixel during exposure time. This can be done by reducing the exposure time of the camera. However, reducing the exposure time will also make the image darker (as there is less time to capture light). Illustration of the effect of motion blur How to make your setup more light sensitive If your image is too dark you can check one of...

Applications with fast moving objects, often need a high framerate and short exposure time. Short exposure time comes with less light, meaning a light sensitive lens and image sensor are required. Here is an overview of settings that will help you find the optimal settings in your high-speed application. You can use this as a guideline. Set the correct Exposure Time The first setting to optimize is the exposure time. The maximum exposure time is 1/framerate. If you want to achieve 200fps, the maximum exposure time is 1/200= 5ms. The lower the exposure time, the darker the image, therefore you want your exposure time to be as long as possible to increase the brightness. However, it is limited by the calculated maximum exposure as shown above. Another important limitation you need to be aware of is the maximum exposure time to...
Depth of field is important for acquiring a sharp image of an object you are inspecting. With the right use of depth of field, you can ensure that the object you inspect is in focus, while the background and foreground are not in focus. That way it is easier for your vision software to recognize your object. Depth of field is an important factor that you can use to your advantage. This article will explain what depth of field is, and how to use it. What is depth of field? Technically, the depth of field is the distance between the nearest and furthest object of the image that is in focus during acquisition. In the image below, the working distance is 250mm. The closest object to the lens is 190 mm away. The furthest object is 250mm away and in between is an object 210mm away from the lens. If your camera set up has a...
Gamma is a machine vision technique used to correct the difference between the digital image readout and the perception of the human eye. It can also be used to correct over illuminated spots. This is a detailed article about Gamma correction. What is Gamma Correction? A camera sensor converts light intensity of a pixel into equivalent digital value. The digital value is directly proportional to the light intensity of a pixel and hence has a linear relationship. However, a human eye perceives the images as a logarithmic function of intensity instead of a linear function. If the images from a camera sensor are directly displayed on a display device, then the scene will appear unnatural because of the differences between the camera sensor and human eye perception. To compensate this, the image from the camera sensor goes through the...

When selecting the most suitable Gigabit Ethernet camera for your machine vision project, you should know the differences between industrial cameras with and without Power over Ethernet (PoE). PoE means that the CAT6 network cable simultaneously works as communication and as the power supply for the camera. You can recognise a camera with PoE by the article number with a “-P” at the end. For example, the MER2-630-18GC-P is our 6,3 mega pixel camera with Power over Ethernet, while the MER2-630-18GC has the same image sensor but no Power over Ethernet. Both cameras with PoE and without PoE have their advantages and disadvantages. These are explained below. Why choose for a camera with Power over Ethernet Using a GigE camera with PoE is the most convenient way to power your industrial Gigabit Ethernet camera. You only...
Global shutter is used for capturing moving objects, while rolling shutter is used for capturing still images. A rolling shutter camera is cheaper, especialy for resolutions above 1.6 Megapixel. For example, our 12MP rolling shutter camera costs approx. 200 euro: MER2-1220-32U3C . In contrast, our 12MP global shutter costs approx. 1000 euro: ME2P-1230-23U3C . A Global shutter has larger pixels, therefore a larger sensor as a rolling shutter camera. As a result, a global shutter camera is more light sensitive and produces sharper images. Exposure and Shutter Exposure time is a period of the shutter from open to close. During the period, the light exposing on the chip’s photosensitive array and Photoelectric effect occurs. After that, photoelectric charges are produced. By the A/D transformation, the...

The use of (color) C-mount lens filters is to be able to create contrast between colored parts of an object with a monochrome camera to easily detect and measure the specific part of the object. Additionally (color)C-mount lens filters are used to block external-environmental lighting. Why monochrome camera and not color? Because monochrome cameras are up to 3 times more light sensitive and produce sharper images. (Color)C-mount lens filters can be applied to camera lenses without significant loss of light or image quality. Color lens filter principle Using a Color lens filter to add contrast works on subtraction idea. For this example we take a red bottle cap with red lens filter. The red Lens filters does not brighten up the cap. Instead, the complementary colors and the colors close to the complementary colors are...
