Decide which problem you are actually solving
Camera translation converts the text on the page. That is enough for a menu written in a language close to your own, where “grilled sea bass with fennel” means exactly what it says. It is not enough where the name of a dish is a name rather than a description: a correct translation of “tête de veau” is “calf's head”, and a correct translation of 螞蟻上樹 is “ants climbing a tree”, which is minced pork with glass noodles. In both cases the translation is right and you are no better informed. A menu app closes that gap by describing the dish, listing its ingredients and flagging allergens, which is a different job from translating.
