Image Editing versus Image Processing and Low Frequency Flat Field Correction

Image editing vs image processing

Image editing is often thought of as image manipulation, a word with nasty connotations. Image editing is about changing the image in some way, you could say manipulating it. However, “I photoshopped a picture from my fishing trip,” conjures up images of making the minnow you caught into a prize marlin when perhaps all you did was heighten the color saturation or increase the contrast. In contrast, image processing is about bringing the information out of the noise. Image Processing is the science of image enhancement and includes photo editing. Both enhance the image and both can be used to bring out otherwise hidden information but image processing is all about bringing the information out of an otherwise noisy scene. Image processing is generally about applying equations and algorithms to images to make data stand out, be easier to detect. Image processing is what Adimec does to generate True Accurate Images and remove system defects and artifacts so that the scene image is accurate.

Resolution versus Field of View

Posted by James Hendrix on Thu, Sep 28, 2017

When we talk about more megapixels for a sensor our first thought is that we have higher resolution which in some sense is true but really what you get is an increased field of view (FOV) given the same optics, scene and pixel size. Field of view is the angular extent of the image scene and resolution is the number of pixels on target. See the figures below for examples. The first shows a patterned semiconductor wafer and the relative area or FOV each of several cameras sees given the same optics, distance from the sample, etc.

How do you choose a Lens Mount for an Adimec Camera?

Posted by James Hendrix on Thu, Sep 14, 2017

For most Adimec cameras you get a flat plate interface that references to the sensor and all applications require optics in front of the camera so you really need a lens mount If you look at our lens mount selection it is easy to be overwhelmed, but fear not. This blog will cut through the complexity and make the choice relatively simple. The first task is to identify the camera that you need a lens for. Simple, right? Then you determine the screw pitch based on the model number from the handy dandy overview sheet below.
