Should I learn about computer vision when I want to work in NLP?

Hi!

I'm going through the deep learning specialization of deeplearning.ai in Coursera and I've finished the first three basic courses of it. Though right now I'm entering convolutional neural nets and it's all about image processing and computer vision. I know I want to continue NLP as my major field of research but I'm not sure whether I should learn about image processing or not? Do you think I should take the time and go through this course? Do these fields relate to each other?
Thanks in advance!
