Android Question cameraEx Photo Size (with,heigh)

TheArkhangel · Aug 4, 2016

Greetings to all
Would like to know using the library and the module cameraEx as forcing the device to take a picture with a certain size (4260x3180), knowing in advance that the device has the resolution.

The application on my LG G4 makes the images with a resolution of (5312x2988) whereas if I install a BQ Aquarius M5 always makes the photos (160x200) and click on the button indicates resolution change ..... that is selected (4680x3120).

Can anyone tell me where failure?

What is the output of Log(CamEx.GetSupportedPicturesSizes) ?

TheArkhangel · Aug 6, 2016

B4X:

Sub Camera1_Ready (Success As Boolean)
    If Success Then
        camEx.SetJpegQuality(96)
        camEx.SetFocusMode("continuous-video")
        'camEx.SetPictureSize(4160,3120)
        Log(camEx.GetSupportedPicturesSizes)
        camEx.CommitParameters
        camEx.StartPreview
        Log(camEx.GetPreviewSize)
       
    Else
        ToastMessageShow("Camara no disponible.", True)
    End If
End Sub

the log...

** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
0
[Lb4a.example.cameraexclass$_camerasize;@dcad7f3
[Height=1080, IsInitialized=false, Width=1920
]

My smartphone are a LG g4 the photos size default with the app are (5312x2988), the same app installed at BQ Aguarius M5 photo size are 160x200 but when touch the resolution button the message see (4160x3120) but no make the photo at this size, I don`t have the BQ device to connect and see the log.

I use the line commented to change the photo size and send the app but now i don't have a response if it's ok or failed.

Why can made to app detect the max resolution and set it for default photo ?

Change your code to:

B4X:

For Each cs As CameraSize In camEx.GetSupportedPicturesSizes
   Log($"${cs.Width} & ${cs.Height}"$)
Next

de commented line 'camEx.SetPictureSize(4160,3120) I change for first resolution and ok........ my question.....how to made the app use ever the first resolution o the most high ? Becouse I dont have other smartphone to know who resolution are ok.....

Something like:

B4X:

Dim maxSize As CameraSize
For Each cs As CameraSize In camEx.GetSupportedPicturesSizes
   If Power(cs.Width, 2) + Power(cs.Height, 2) > Power(maxSize.Width, 2) + Power(maxSize.Height, 2) Then maxSize = cs
Next
Log($"${maxSize .Width} & ${maxSize .Height}"$)

Thanks Erel
All correct, now the app detect de max resolution of the device and take the photo with it.

This is the code for event camera ready

B4X:

ub Camera1_Ready (Success As Boolean)
    If Success Then
        camEx.SetJpegQuality(96)
        camEx.SetFocusMode("continuous-video")
        camEx.SetPictureSize(5312,2988)
        camEx.CommitParameters
        camEx.StartPreview
        Dim maxSize As CameraSize
        For Each cs As CameraSize In camEx.GetSupportedPicturesSizes
           If Power(cs.Width, 2) + Power(cs.Height, 2) > Power(maxSize.Width, 2) + Power(maxSize.Height, 2) Then maxSize = cs
        Next
        Log($"${maxSize .Width} & ${maxSize .Height}"$)
   
    Else
        ToastMessageShow("Camara no disponible.", True)
    End If
End Sub

You should learn from the code.

You always set the picture size to 5312x2988. No matter if the camera support this resolution or not.
Then you calculate the biggest resolution... But you do not use the info you found.

DonManfred sorry, at the code I not comment the line

camEx.SetPictureSize(5312,2988)

As you see it this line set the picture size resolution to 5312x2988

At my code the line are commented and the app work fine.

Thanks.
