Continuous movement is important for a thorough scan result. We recommend moving the device over the bin , so that you have covered over the majority of the fruit within 10-15 seconds. |

In some instances, the color accuracy is impacted negatively if the white balance is changes changed during a scan. This may be because the iPad has auto-adjusted the white balance to a range based on lighting conditions not reflective of the scanning environment. For example, if the iPad camera was in a dark settingplace, and then an you immediately attempt to scan is started immediately in a brighter lighting conditions place without any pause for auto-adjustment, white balance inaccuracies can occur.

When scanning fruit smaller than the standard size (apples), the resolution of the images captured in the scan can be adjusted for better results. In the HQV preference menu, there are options for changing the default resolution of the scans. For fruit that is cherry size -sized or smaller, the recommended resolution is ‘Ultra High’. For fruit the size of a prune plum, the ‘High’ resolution setting is recommended.

You can assess the quality of your scan’s data capture after you tap the Stop button. Review the scan coverage by moving the camera around the area you just scanned to see that the fruit in the bin is covered fully and that you have not scanned anything else that is at a vastly different depth, like such as the ground.
You can also check scan quality by looking at the scan reconstruction on the web browser.
