When the images are blurred or out of focus, almost always it has to with focusing.

1. Make sure the object (i.e. document) fill the screen of the camera and leave the blank black space as little as possible because you want the camera to focus on the document, not on the black cradle underneath it. If there's a lot of black cradle inside the frame and is part of the shot, of course there's a possibility that the camera will look to focus in on the cradle (background) instead of the document (object) that you want to shoot.

2. Use AF mode

3. For AF setting, select "One Shot" setting because that's the most suitable setting for our type of application (shooting stationary object) for "AI servo" was more suitable for shooting moving object and AI focus is the combination of both modes.

4. AF point, select Average.

When you capture an image with a Canon DSLR, the information such as shutter speed, focus length and focus point will be added to the image and can be viewed using the Canon also included software named “ZoomBrowser EX”, which should be part of what’s installed when you install the camera driver.

In ZoomBrowser, simply choose your image and double click. Then click on "Show Auto Focus Points" on the menu.

The red square depicts the focus point of the image taken. It the focus point is on your document, the image should come out fine.

However, you may want to retake the shot if the focus point was on something else (i.e. the black cradle) besides the document.

When shooting a blank page, dark page or page with little text on it, the camera may fail to focus. This is normal for DSLRs (which use passive autofocus). In plain English, DSLR cameras always need something to focus on. Without something to focus, it will not shoot.

If you experience a focus failure, please understand that the computer is not locked up. It just waits for assistance from the user. Once assisted (help the camera to focus) and the camera can shoot that page, user can go with shooting next pages.

Here are 2 simple ways to deal with the issue:

A. Decoy

Create a decoy for focus and then remove it. Here are the steps:

1. Once the camera has focus failure, insert your hand or a sheet of paper into the scene on top of the glass.

2. Press and hold the shutter button halfway. You will hear the sound of the cameras able to focus on the decoy (your hand or paper).

1. The decoy from the scene while still holding the shutter button halfway.

2. Now fully press the shutter button so that the camera captures the blank page.

Once the failed camera was able to take a picture, you can continue scanning next pages.

B. Post it note

The easy solution is to create a small post-it note that says something along the lines of "scanned by ABC Library". Whenever a blank page pops up, just throw this post-it note on top of the glass so that camera can takethe picture.

1.Copy the file "atizsys.lic" onto a flash drive. This file can be found on C:\Program files\Atiz\BookDrive Capture or BookDrive Editor Pro\atizsys.lic

2.Copy from the flash drive onto another PC that's connected to the Internet.

3.Open a web browser. Go to http://www.atiz.com/software/register Upload the file and submit. Atiz web will generate the activation code on the page. Please write it down on paper.

4.Use that code and fill in the activation code dialog box on the installed PC. Click "Activate". Done.

1. First, you have to deactivate the software on the old computer. Open the program thatyou want to deactivate, Click Menu / Help / Deactivate
2. You will see the deactivation window. Click "Deactivate".
3. The deactivation process is complete.
4. Install the program on the new computer. You have to go through the activation process again(as if you're activating the program for the first time) to obtain the new activation code for useon the new computer.

You don't actually take images with any DPI settings. All you captureis a number of pixels. DPI or PPI settings are only relevant when you want toachieve a specific physical size, such as when you go to print. Until that timeyou are working entirely with Pixel Dimensions.

Now it just so happens that in the EXIF data fields there is an entry for a DPIsetting. For Digital Cameras this is purely a recommendation and whatever themanufacturer decides upon. If there is no entry then the default is 72PPI.

It's real use is for electronically scanned documents, for example, whichfinish up as a number of Pixels. To get it to reproduce at the same physicalsize as the original the scanning DPI would be included.

The magic formula is :-
Pixel Dimensions / Resolution = Physical Size

Unless you are printing directly from the camera DPI is meaningless.

There is no difference in quality of the image you havetaken. You have still captured the same number of Pixels.

Let's for example assume you have a 6Mpixels camera which produces images of3000 x 2000 pixels. Marking these as 72, 300, 1024 or whatever PPI makes nodifference to the source image - it's always 3000 x 2000.

Now let's assume you want to print this.

If you want to print a 6 x 4 then the resolution will be 500PPI

3000/500 x 2000/500 = 6 x 4.

If you want to print at 10 x 6.67 then the resolution is 300PPI<

3000/300 x 2000/300 = 10 x 6.67

Pixels Per Inch or PPI (often confused with DPI) is a physical dimension - yourcamera has no concept of the physical size of the resulting image. That's foryou to decide when you print or display it.
