Settings

The application allows the following settings:

Display Settings

Sort by last name Here you may decide that names are not ordered strictly alphabetically as given, but by the last name.
Guided setup of iris and pupil position Here you may decide if you are guided through setting the iris and pupil position before you can display overlays.
Default overlay color Here you can define the default color for iris topography overlays. (Standard: red)
Language Here you can change the language in which the app is displayed. A value change forces a restart of the app.
Display all hints Here you can re-enable all hints.
Do not display hints Here you can disable all existing hints (which is helpful after new installation if you know the app already).

Storage and Memory Settings

Eye Photo Folder

This is the folder in which the app manages the eye photos. Normally, you need not change this. From here, you can copy the photos to other devices.

The predefined folder is “EyePhotos”.

You can select here a folder either on your device memory or on an SD card. In Android 4.4 (Kitkat), storage on SD card has some limitations, therefore some operations will take longer. In Android 5, when selecting a folder on SD card, you will have to grant access rights to the SD card via Android's Storage Access Framework.

Max Bitmap size This is the size to which photos are scaled down before displaying. This downscaling is required to save device memory. The default value is 2048. In devices with little memory, it may be required to configure a smaller value (such as 1024). Too big values may crash the application.
Show image in full resolution Here you can decide under which circumstances the photo is displayed in full resolution, which allows to see more details on the photo, but consumes memory and computing time.
  • Always load automatically: The app always stores the photos in full resolution in memory. This gives the best user experience on high end devices, but may lead to crashes if there is not enough memory available.
  • Load automatically when displaying single photo: The app shows full resolution only when displaying a single image. This requires half of the memory.
  • Load only on demand: The app does not show the image in full resolution. This requires least memory and CPU, but details in the photo may be lost. The “magnifier” button allows to display the current picture detail in full resolution.
Save additional data in jpeg Here you can limit the storage of data in the JPG files by the app.
  • Store in EXIF (recommended): The app stores relevant information in the JPG file, even in standard fields which are visible in Windows.
  • Store in custom fields: The app stores information in the JPG file, but only in separate fields. Standard fields remain unchanged; the data exchange with Windows is not possible.
  • Don't store data in images: The app does not store information in JPG files. (This limits the functionality of the app.)
Automatic detection of iris Here you can select if the app should automatically try to find the position of iris and pupil in the eye photos. This typically will simplify the positioning of overlays, but it requires many resources of the phone, and the result may be incorrect.

Camera Settings

Start with left eye Here you can define which eye should be photographed first. By default this is the right eye.
Camera compatibility If your device runs on Android 5 or higher, then here you can select if the camera functionality should use the new Android 5 features or not. Selection of “Android 4” makes sense in case of issues with Android 5 compatibility.
Enable flash Here you may enable the flashlight functionality. By default, this is disabled, as it is dangerous to use the flashlight close to the eye.
Enable external LED flash Here you can set whether the use of a “Flash & Fill-in Light” plugged in the headphone jack should be supported.
Use front camera Here you can specify to use the front camera for taking pictures. By default, the rear camera is used.
Show link to Camera App Here you can specify if the button for taking photos with the system camera app should be displayed.
Camera screen position If the Miniris ribbon hides some buttons on the camera screen, then you can use this setting to shift the camera screen to the right or left.

Overlay Button Configuration

This page allows you to define which iris topography overlays can be displayed by pressing the overlay buttons. The same setting can also be done while displaying the photos, by making a long click on some overlay button.
