Morphology
camera + obscura
The phrase literally combines 'camera' (a chamber/device) with 'obscura' (from Latin for 'dark'), so knowing both parts would point toward a 'darkened chamber/box' and thus partially reveal the projected-image sense. However, 'obscura' is not a common English word and the modern sense of 'camera' (photographic device) can mislead learners; the term is technical/loanword rather than everyday composition. Cross-linguistic cognates (e.g. Spanish 'cámara oscura') make the logic more inferable, but because knowledge of the specific form 'obscura' is required, I rate it semi-transparent.
Etymology
Camera obscura comes from Latin words camera 'room' and obscura 'dark', and it was a dark room or box with a small hole that let light in. The hole made an upside-down picture of the outside on the opposite wall, so the name helps you remember it is an early way 'to project' an image.
