NEW !!!


Test chart measurement procedure of moving objects  published !!!



Sharp and clean images are only possible when the viewed scene is still and has no moving objects.
In the world around us there is constant movement which affects the clarity and sharpness of objects. It is impossible to have sharp recorded footage even with the best camera and lens, without understanding the effect of moving objects in the recorded video.



With this new measuring procedure, ViDi Labs makes it possible to quantify parameters that influence bluriness of the recorded moving objects.



Measure the effect of moving objects on camera image ("object blur due to pixel shift effect").



This is the latest procedure with the ViDi Labs SD/HD test chart which allows determining the pixel blur due to moving objects.



The illustration and formula on the left are produced by Vlado Damjanovski and can be used to determine the effect of moving objects of any speed and at any distance on a camera recorded image. It can be applied on any type of camera, be that IP CCTV, still image DSLR or a motion picture camera.



Typical examples are moving vehicles where traffic authority or security operators want to determine the number plates, or perhaps, recognise a face of a person running in front of a camera, or in sports action recording.



The photos on the left are a practical example of the effect of an oscillating test chart, the calculated pixel shift and it's appearance in an exported frame, which is in accordance with the derived formula. 



You can produce similar measurements by ordering the test chart, above.

There are four test chart snap-shots from four different lenses shown on the left.

For obvious reasons there are no lens manufacturer's names mentioned.

All lenses are claimed to be mega-pixel lenses.

The same camera is used throughout and all camera settings are identical. The angle of view, compression settings and illumination are also identical.

All lenses are focused for best possible image.

Even though the exported images are reduced and cropped (for the purposes of displaying on the web site) the image quality is obviously different, the top one being the best, and lowest being the worst.

All lenses are vari-focal, mega-pixel and within a similar price range.

Lens quality may be one of the most important factors in obtaining the best possible image for your cameras.

The ViDi Labs test chart is one of the easiest and optimal methods for objective comparison and testing.
