Morphology
television + pickup + tube
The phrase is largely compositional: 'television' (TV) + 'pickup' (to pick up or receive) + 'tube' (an electronic tube) together denote a tube that picks up or receives television images/signals. A B1 learner who knows those constituent meanings can reasonably infer the technical function, so the construction is transparent.
Etymology
Television pickup tube comes from early TV cameras where a glass tube would 'pick up' light from a scene, which is why the word pickup is used, and then change that light into an electronic signal. That's why the name means a device that receives an image and makes an electronic signal.
