Introduction

This explanation assumes that the i-PRO camera application development environment has been completed.
If you are not ready to build the development environment, please refer to here to complete it.

Also, in this tutorial, the SDK installation directory is described as ${SDK_DIR}.

Operation overview

jpeg_app is a sample application that saves camera images in JPEG format.
You can save an image like the example below.

How to change preferences

This application has some preferneces which a user is able to change.
When changing some preferneces, push "AppPrefs" button in "ADAM OPERATION UI" html page.

Resoultion:
Resolution to get jpeg images.
Specfify QVGA(320x240) or VGA(640x480) or HD(1280x720) or FHD(1920x1080).
However, by the ability of the camera, it may not work with the specified value.

Frame rate:
Frame rate to get YC(YUV) images which are encoded to jpeg images.
Specify 1 or more.
However, by the ability of the camera, it may not work with the specified value.
