Using the EMVA1288 standard
By Linus Frantzich | Comparing the performance of two image sensors can almost be an administrative, rather than a technical task. Most image sensor metrics depend on exposure time, gain, lens performance and temperature to name a few. Including all conditions and comparing using the same conditions exponentially increases the adminis
Sharpness and resolution, part II
By Henrik Eliasson | In the previous post we looked at the relation between optical resolution and sharpness. We could see that there is no clear correlation between the two. In this post we will complicate things a little by including the pixel resolution (we therefore assume a digital camera) into the mix. The last […]
Sharpness and resolution, part I
By Henrik Eliasson | Sharpness is one of the most important image quality attributes for a camera. Often, the sharpness and resolution of a camera system are confused and used interchangeably. In this post, I hope to sort out some of the confusion. Figure 1. Same scene captured with two different lenses. In Figure 1, […]
