Scanned images of the front and back sides of postcards, New Year's cards, business cards, etc. are output as a single composite image file after correcting the shooting angle.
[How to use]
When a rectangle is recognized, it will be surrounded by a red frame and displayed on the screen, so press the shutter button.
After scanning the front and back sides, a combined image file is generated.
The image is automatically corrected to the data acquired from directly above.
*It is also possible to save images without automatic correction by changing the setting.The first image and the second image should be scanned in the same direction.
For example, if you scan the first image vertically, you must also scan the second image vertically.To cancel the first image, press the menu button to display the setting screen and click Return.
It is also possible to change the setting to save images one by one instead of generating double-sided images.
Automatic correction speed can be increased by specifying a fixed aspect ratio.
When processing standard postcards of the same size continuously, image correction can be performed faster and more accurately than automatic correction.
For example, for a fixed value, set "1.48" for the official Japanese postcard (100 mm x 148 mm).You can select whether to output the image to the built-in memory or the SD card. The captured images are output to the following folders.
