The Plane with image texture blured when I rotate it

Hi, guys, Im a beginner on three.js.
I create a plane and add a image as texture on it, I use standard material:

and when I roate it, I got:

the more it not towards the camera, the more blur I got.
How to avoid this?

var maxanisotropy=renderer.capabilities.getMaxAnisotropy();
texture=new THREE.TextureLoader().load("image.jpg");

thank you so much Chaser! Love you!
