Leaflet: Image Overlay and zoom levels

I added an image to my map (image overlay). Can I "adjust" the zoom levels due to the image?

At zoomlevel 17, the resolution of the raster map is too low compared to the screen resolution. At zoomlevel 16, the raster map isn't readable anymore.

Is it possible to define something like "zoomlevel 17: 1px of the image = 1px of the screen"?

Please excuse my bumpy English. Thank you very much!

var map = L.map('image-map', {
  minZoom: 16,
  maxZoom: 18,
  }).setView([46.975768, 7.436308], 17);


var imageUrl = '../Bilder/Karten/Normalansicht.png',
    imageBounds = [[46.966635, 7.415942], [46.998849, 7.470108]];

L.imageOverlay(imageUrl, imageBounds).addTo(map);

map.setMaxBounds(imageBounds);
