Sure, here's a two-paragraph answer to the question How do I scan and translate a picture in Google Translate?
To scan and translate a picture in Google Translate, open the app and select the language you want to translate to. Tap the Camera button and hold your camera up to the text you want to translate. You can also snap a picture to manually select text or open an old picture from your gallery. For iPhone and iPad users, download the language you want to translate to and from, and select Detect language to automatically recognize the language. Then, tap the camera icon, select the language you want to translate to, and tap the scan icon. Point your camera at the text you want to translate, and the app will translate it in real-time.
Alternatively, you can also use the Import feature to translate text from photos on your camera roll. To do this, tap the Gallery button, select the photo you want to translate, and highlight the text you want to translate. The app will then translate the selected text, and you can hear the translation by tapping the speaker icon. Additionally, Google Translate's instant camera translation feature allows you to point your camera at a sign or handwritten text, and the app will translate it in real-time. To use this feature, download the Google Translate app, and tap on Instant to point your camera at the text you want to translate.
