I need to start the Camera activity from within my application, take a picture, and return the photo URI to another activity. Surely this should be straightforward? But the Camera API sample code doesn't show how to get the URI. I can't find the answer on this forum, either.
I am working on image processing in mobile. When Camera,takePicture(null,null,pictureCallback) called I am getting (640*480) JPEG image data, its taking 1 second delay.When I try to get raw data it returns null value.I am interested only on delay.
My application while compiled in 1.5 works fine. I had some memory issues w/ 1.6 due to image size, which was strange b/c the image size increased when taking photos by taking a picture w/ surfaceholder/imagecapture callback. I seem to have fixed re-displaying those images by resizing them using a bitmapfactory matrix. But my camera is now rotating everything 90 degrees. It appears that my Override of surfaceChanged does nothing, which is where I was setting rotation at 90 (I can't remember why, it was 10 months ago!). I have tried at rotating the camera parameters paramters at 90 degrees, 0 degrees.
I'm writing an application for Android. I need to make some image processing on the picture taken from camera.I use Camera.PictureCallback to get the photo, and I get picture in byte array.The problem is I want to make operations on every pixel of photo (some filtering and other stuff) so I guess, have photo in byte array is not a bad idea. But I don't know how interpret information in this byte array... The only way I know to make the processing is use BitmapFactory.decodeByteArray() and then use Bitmap object. Is this a good way to handle a lot of image processing?
I am working with camera.. I am facing one problem during capturing image.The image is not saving directly to gallery.But when i reboot my device its appearing. Can anybody tell me why this happens.and How can i solve it.
I am using BitmapFactory.decodeFile to load Bitmaps of images into my application. However, the function returns null on large images (such as those from the camera). The filepath is definitely correct, I just can't figure out why it would return null. I tried supersampling, but it didn't seem to help.
Does anyone have any idea why it would do this or how I could more easily load images taken from the camera into a Bitmap?
At the moment I am attempting to set my camera on my Motorola Droid phone to take an image that matches the size of my screen (854 x 480 pixels), and I am attempting to accomplish via the parameters for the camera as such:
I have my activity implement the Camera.PictureCallback method of onPictureTaken (excluding log calls), so when the takePicture method is called it runs this method:
For some reason though, my camera is taking pictures in 1280 x 960. Is this some sort of minimum size the camera can capture an image in? From log calls I can see that the Camera's parameters are still set to have a picture size of 854 x 480, but image keeps coming out as 1280 x 960. Am I decoding the image incorrectly, am I setting the camera's parameters incorrectly, or am I doing something else wrong?
I'm using this camera code to ask the camera to rotate the captured image data... this seems to work on all phones, except the Droid. Has anyone else seen this? The image data is always landscape, however, the native camera app produces portrait images OK. I wonder if the Droid will only respect the new Camera.Parameters.set Rotation() method, but this seems to only be available in sdk level 5?
so i have an intent that use the system camera. so after i taken the photo, it brings me back my application. I want to display the image (just taken) as a thumbnail. How do i retrieve that latest image from Media Store.Images.
I worked on N95 mobile, my goal is to capture image for every 2 min and send the image data to server without user help. I am done with image capturing manually but I am unable to capture image automatically could you please suggest me. I am getting certification message pop up. Is there any way to start my application automatically. I am messed with code signature and manufacturer agreement with Nokia. So I have decided to change the platform to Android mobiles. Could you please let me can I able to implement the above application in android mobiles android platform.
I have a camera application that captures a 640x480 image.I want to convert this image to grayscale.I know I have to use the setSaturatio (float sat) in the ColorMatrix method to zero but I don't know how I can set it to grayscale.
As far as i know, Android emulator doesn't have a camera. To capture a live image we have to use the web camera. I have seen code in this web site to use the web camera in the android emulator to capture an image, but I don't know how to use this code.
Today I tried the sample code to get the camera preview working (http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html) But the image looks distorted when I start the application on my Galaxy S.
I am trying to implement Camera application in android,and i got some code from net to create a Live Camera through WebCam.Upto this no problem.Now i have to capture the images when click the button, and i displayed the captured images in the Dialog window.Without any exception the program is running but the captured image is not displayed,some default image is displayed.
My code is.
I have no idea from where this default image is coming.
I am having a problem capturing an image and storing it from the native camera app. Here is a sample of some of my code.
After the picture has been taken and I'm returned back to my original Activity, When I navigate to my sd card via Android DDMS File Explorer the picture is not there. Anyone know why this is not being saved?
This is the code that I have for camera preview and image capture.I am trying to do camera preview and as I press the space button I am trying to take picture and save it in the picture gallery of the Android development phone. The code compiles fine,but as I press the space button,it captures the image and throws an exception and closes the application...
On the G1 camera app, there's a handsome looking camera button which you can press to signal the app to take the picture. It's a round button with a little camera icon in it. Is that button resource available in android.R? I'd like to use it in my own app if possible?
I get the Failed binder transaction error in the logcat when returning the image taken with the camera from the camera intent back to the parent intent (as a byte using putExtra). I don't understand why, its not like its a big bitmap or anything. It only happens when i take pictures with lots of light, because then the byte is bigger. The error occurs when leaving the camera intent. Does anyone see a mistake in my code?
Here is the code of the camera intent:
And here is the code that calls the camera intent:
I managed to figure out how to get the camara application to give me an image, but it is rather tiny, only 18k. Has anyone figured out a reliable way to get a full-sized image returned if you are using a MediaStore.IMAGE_CAPTURE intent?
I'm using the android SDK in Eclipse on Linux. I've used the code at itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf to write an app to store an image captured through the camera onto SD card (there are various examples of this around). It works ok except that the image returned by the camera is not what's on the preview surface. Instead of getting the checkerboard image I expect, I get different versions of the android icon depending on which version of target I choose. If I render the image to an ImageView this is confirmed as it's the same as on the SD card.
