Currently Google Translate’s camera translation supports only a few languages. If you select an unsupported language, the camera icon will not be displayed on Google Translate app. Moreover, to use Camera translation, you need a data connection and requires Android 2.3 and above.
Using camera translation or image translation is quite simple. – Open Google Translate on your Android phone and select a desire language that you want to translate. If the language supports camera translation, the camera icon will be displayed at the bottom right of your screen. – Tap on the camera icon to take a snapshot of the image. Focus the image correctly to get a clear picture. – After taking the snapshot, highlight the text on the image (that you want to translate) with your finger (draw carefully above the text on the image with your finger). If the text selection is perfect, Google Translate will process and displays the result. Final thought: For me, camera function of Google Translate is a superb feature; however, it is unfortunate that many languages aren’t supported yet. However, I am sure that Google will add more languages in the next update of Google Translate for Android.
