I've noticed that a lot of people (myself included) have an issue with the camera's auto focus. The problem is that most pictures will go slightly out of focus. Even when touching the viewfinder to focus manually you can see the picture focus perfectly before going slightly out of focus and "going green" to indicate it thinks it's focused correctly.
I was trying to take some photos from the audience of performers on the stage, and the camera was really struggling and failing to Focus. Understandable, that the lighting would be difficult for an auto-focus setup, so I dug into the settings.
The choices under Focus are: Auto, Manual, and Face tracking.
I am developing an android app in which when i open camera intent, i would want something like this screen-shot from the app Keyring. Instead of the Bar Code, I want to capture a Credit Card. A border for the user to focus the card in, Auto-focus the image and Auto-Capture. Please give me direction! Any help will be appreciated.
Also, Can this be done with Action_Image_Capture Intent?
i know this has been discussed on the site and people seem to be split about the rattle which i have on noticed when i set my phone down on a hard surface and of course if i shake it. it still shakes when auto focus is locked also.
I have been building my own camera app for a couple of days now, faced and fixed a lot of issue[orientation,video rendering etc...]. I was trying to achieve the auto focus exposure("Informally known as touch to focus") and i have not been able to get the white brackets(in some phones a green circle that appear around the focus region, apart from this the auto focus feature is also working.
I bought a Canon dslr that came with an 18-55 IS that does not work on auto focus. The seller said it was the lens an not the camera, I do not have another lens to test right now though. I saw a couple of links where they were saying this is a potentially cheap and easy fix, has anyone here did this?
