I have an smartphone device with a camera. I would like to obtain and process this image data in MATLAB.
(Specifically, I have an Android device).

Hello, is it possible to edit the exposure of the android camera?

If you happen to use the same product as was discussed in the link on instructables then the vendor sight says that exposure is adjustable. https://www.e2esoft.com/ivcam-camera-settings/

You can use DroidCam if you are using an android phone. You'll need to install OS Generic Video Interface driver.
Hope it helps. :)

for anyone that can't find the correct address for droidcam simply connect to droidcam using your browser and click on the i button. It should look like this
http://192.168.1.61:4747/mjpegfeed?640x480
and then
camera = ipcam('http://ipaddress:port/mjpegfeed?640x480')

With the iPhone, using the App suggested by Ashish above (IP Cam), you can achieve the same pretty easily! The code is exactly the same:
url = 'http://<ipaddress>:8020/image.jpg';
ss = imread(url);
fh = image(ss);
while(1)
ss = imread(url);
set(fh,'CData',ss);
drawnow;
end

is the IP address for the android webcam streaming live video or simply a single image or series of saved images?

ipcam() was not introduced until R2015a, a year after amro posted their Answer.

Here's the working code for color detection using android camera:
url = 'http://192.168.0.100:8080/shot.jpg';
framesAcquired = 0;
while (framesAcquired <= 50) % the vedio will work till the 50 video frames, after that the vedio will stop. You can use while(1) for infinite loop
data = imread(url);
framesAcquired = framesAcquired + 1;
diff_im = imsubtract(data(:,:,1), rgb2gray(data)); % subtracting red component from the gray image
diff_im = medfilt2(diff_im, [3 3]); % used in image processing to reduce noise and for filtering
diff_im = im2bw(diff_im,0.18); % convert image to binary image
stats = regionprops(diff_im, 'BoundingBox', 'Centroid'); % measures a set of properties for each connected component in the binary image
drawnow;
imshow(data);
hold on
for object = 1:length(stats)
bb = stats(object).BoundingBox;
bc = stats(object).Centroid;
rectangle('Position',bb,'EdgeColor','b','LineWidth',2)
plot(bc(1),bc(2), '-m+')
end
hold off
end
%stop(vid); % to stop the video
%flushdata(vid); % erase the data video
clear all

I am not sure if this is exactly what you are looking for. However, you can use 'Simulink Support Package for Samsung GALAXY Android Devices' or 'Simulink Support Package for Apple iOS Devices' to access the appropriate smartphone camera. Both these support packages come with a Camera block that allow you to get the Camera data inside MATLAB. You can subsequently connect the Camera block to a Video Viewer block if you would like to visualize the data in Simulink.

You would either have to write the code in MATLAB and use MATLAB Coder, or else you would have to create a Simulink model and deploy that to Android.

You need to replace he "MY_IP " part by your actual IP address, such as http://192.168.0.10/shot.jpg

Hi All,
I found out that;
imread('http://MY_IP /shot.jpg');
works only on secured network for me. If I am on a public network, then it gives error.

Hi, there is a new feature on Apple devices (Continuity Camera) where we can directly use our phone's camera as our mac's webcam. With this feature activated, when using the command imaqhwinfo, i only see my mac's webcam and not my iPhone camera. Is there a way to acquire video (live) with my iPhone's camera ?
