Lenticular Photo Processor

Purpose of the program

Lenticular Photo Processor program is designed to take the frame sets obtained by the Lenticular Photo Capture program and prepare them for printing. Within this program you can load frame sets, control the alignment of the frames not only in the X and Y directions; but also rotational and focal length (zoom). This program also allows you to select the final crop and the final size of the finished image and interlace to the desired pitch. You can then print from this program (picture 1)..

The Lenticular Photo Processor program accepts input formats BMP, PNG, TIFF, JPEG, output files are TIFF. The color mode of input and output files is RGB. The program supports TIFF files with LZW compression. TIFF files containing more than 4 layers are not supported.

Computer System requirements

The operating systems are Windows XP /Vista and Windows 7.

The resolution of the monitor should be 800 x 600 pixels or more. It is a good idea to use as large a monitor resolution as possible.

It is recommended that your computer should have at least 2Gb RAM. More is preferable.

Brief description

One of the most tedious and time consuming parts of the lenticular image process is the alignment of the multiple images in a frame set. This is especially so when multiple cameras are used. The Lenticular Photo Processor program resolves this quickly and easily. By capturing a set of images (one frame set) of our target the program can automatically create an alignment file in about 30 seconds by pressing the button button. This alignment file will appear on the lower right hand side of your screen and can be saved. This file is then used to correct all the frame sets taken at this session as long as the camera set up is not changed and the subjects are at the same location. As you retrieve the frame sets from this session they will automatically be corrected by this file as they are transferred from your hard drive to the Lenticular Photo Processor (Picture 2).

Align file
Picture 2. Align file

The first step is to select the base reference frame; this will normally be one of the central frames. All the other frames will be scaled, aligned and shifted relative to this frame. So, each frame will be shifted by axis X and by axis Y, rotated and scaled. These corrections will all be saved in the special alignment file with align extension. These files can be kept, loaded into the program and used to correct and align a series of frames. All parameters of the alignment are shown in the table in the right bottom corner of your display screen. As long as the camera position and zoom of the camera lenses is not changed during the photo session, you can use the same alignment file for whole photo session whether or not this be hours, days or weeks.. You should keep an alignment file of each photo session on the hard drive of your computer. Use the Save, Load, Reload buttons for the preservation and loading of an alignment file.

Please Note; If the alignment file is preloaded, the frames will be automatically aligned as they are loaded into the program. The values of shifting, rotating and scaling, shown in the table, are used for aligning the frames during loading. Due to the fact that the loaded frames are already aligned, all you need to do next is to select your finished image size and crop. Though it is normally not necessary, at this point you can click the histogram matching button to correct the colors and brightness of the cropped areas of the frames. After that you simply have to interlace the frames and print the interlaced file.

If you have loaded or have reloaded a new alignment file you have to click button Apply, the frames loaded into the program will be aligned with new alignment values.

The Viewing Screen

Viewing screen
Picture 3. Viewing screen

The program has two viewing windows (Picture 3): The main viewing window is on the left. The secondary viewing window is to the right above the correction file numerical display. Using the buttons Slider it is possible to look over the different images in the frame set. Using the buttons zoom you can enlarge or reduce the images. The image in the main left window can be enlarged or reduced by turning the wheel of the mouse.

Program Menus

Lenticular Photo Processor has several different menus. There are File, Alignment, Settings and Help. Let examine them.

- These icons are the main tools of Lenticular Photo Processor program:

!!! Set the best quality settings in your printer driver as default settings. Run Devices and Printers, select the printer, choose from the contest menu (right button mouse click) Printing preferences, set the best quality printing settings and click the button Apply. Your settings will be default.
Of course, select Set as default printer from the contest menu (right button mouse click for the printer icon).

Manual frame Alignment

On occasion you may wish to adjust the alignment of your frames to suit a specific type of image. This can be achieved by adjusting the individual values of the parameters generated in the alignment file for that image.

There are buttons for manual alignment under the main (left) viewing window (Picture 18):

!!! Pay attention, that the keys "-" and "Subtract", and "+" and "Add" are different on keyboard and do not mix them up during your work. Please, see the picture 19.

All these changes are shown in the table of the alignment parameters. Select the reference frame in the main (left) window. The reference frame will remain unchanged and we are going to align all other frames to it. In this example the reference frame is #6 and we are going to align frame #1 to it (Picture 20).

Frames Alignment
Picture 20. Frames Alignment

When we click the button Align relative to the left image, an anaglyph (Red-Cyan) image will appear in the left window for alignment of the right frame image (frame #1) relative to the reference image. An anaglyph picture of the combined images is a user friendly way to show the two frames simultaneously. In our example we see an inscription Align views 1 and 2. This means that the alignment buttons will be effective for aligning the right frame (#2) relative to the left frame (#1). All of these changes will be shown in the table of the alignment parameters.

When you have completed working with this frame just click the Align relative to the left image button again and this will return your display to normal. You can then select another frame on the secondary (right) viewing screen and repeat the previous steps.

Presets for Interlacing

Unlike conventional photography which is easy to resize the images, lenticular images need to have their data reformulated for each different size, lens format used and pitch used or even to suit different viewing distances on images using the same lenticular lens. Our software can save a lot of time as it contains the ability to have a large number of preset options for formulating the image output.

Before interlacing you have to enter into the Lenticular Photo Processor program all information about the lenticular lens you are going to use and the size of your final picture because the program needs this information for generating an interlaced file. We can do that in the Interlacing window (Picture 25).

Picture 25. Interlacing

If you want to make some certain size lenticular pictures using certain lenticular lenses again and again, it is better to create a special preset and use it always when you need it. It will save a lots of your time and effort.

For creating a preset you should:

  1. Enter all necessary information to an Interlacing window.
  2. Close the Interlacing window.
  3. Click the Manage button on the Preset line . Now you will see the Manage Presets window.

  4. Click button.
  5. It is always a good idea to select a name for preset that is as informative as possible to save you time during preset selection. For example it is good to have information about the position, size of picture, pitch of the lens and the name of lens manufacturer if you use the lenses from different manufacturers.

For loading a certain preset you should select one of available presets from the table and click button in a Manage Presets window.

TO deletE a certain preset you should select the preset from the table and click button in a Manage Presets window.

The program works with RGB color model and does not work with multilayered TIFF-files.
