Bitmap Image Quality Missing

Hello! I would like to change the quality of imported bitmap images (which their actual resolution is high), but they appear pixelated. For some reason, the Bitmap Image Quality option appears missing in Camera view if going to Top>View. I also double-clicked the image layer, tried the shortcut ctrl+q, and check the other View menu from the bar above, but none seem to work. Is there a step I missed to find the option? Any suggestions would be appreciated!
