Grouping photos by EXIF values

Leave a reply

Let’s say we want to search for photos taken with a focal length of between 12mm and 18mm.  We enter these values In Easy Photo Search:

and the results will be displayed like this:

as one long list of files on the left.

An alternative to just viewing this long list of files is to group the files.  Say we want to group by focal length, then by aperture.  In the grouping criteria, we select Focal length and Aperture.

Our search criteria then looks like this:

Our search results then shows the files grouped by focal length and aperture.

When we now click on the focal length or aperture item in the search results, Easy Photo Search will automatically display the first image in that grouping.

Working with PNG images containing Exif tags

Leave a reply

We recently received a request from a user who asked if we could add support for PNG files in Easy Photo Search.  We weren’t even aware that PNG files could contain Exif tags, and after some quick googling, we thought that there was no ‘standard’ in how the Exif tags would be stored in the PNG files.

After some more research, we understood that while there is somewhat of a (belated) standard in how Exif data is stored in PNG files, the Exif data block itself does follow the JPEG specifications.  It was only in where the Exif data is stored that may change, depending on the software used to embed the Exif data.  We thus decided to add support in Easy Photo Search to read the Exif chunk in PNG files where possible, as we only need to locate the Exif data block and process it.

Thus, Easy Photo Search 1.2 can now read Exif values stored in PNG files.  Note that you cannot modify the Exif values, nor remove them, from the PNG files at this point.

How Easy DICOM Viewer is different

Leave a reply

Easy DICOM Viewer is a DICOM imaging application co-developed by LISIT, Co., Ltd., a medical software company based in Tokyo, Japan and Yohz Software.

What sets Easy DICOM Viewer apart from the many other DICOM viewers out there?  In this post, we’ll describe the more interesting features and how it benefits you.

Customizable layouts

You can display your DICOM images in a grid with equal sized cells e.g. in a 2 x 2 grid

or in irregular sized cells e.g.

You can define your own layouts, save them, and recall them instantly when you need them.

Custom defined DICOM details

Like most DICOM viewers, Easy DICOM Viewer can display the DICOM tag values embedded in your images.  Unlike most other viewers, you can define exactly which tags you want to display. 

You can then save these tag ‘profiles’, and display them in your images depending on your needs.

Orthogonal measurements

Polygonal measurements in Easy DICOM Viewer include the long axis and short axis values.  This provides you with extra measures to improve diagnosis.

Measuring an area of similar color

This borrows a technique from image editors.  If you have an irregular shaped area that is of a similar color, you can easily measure that area by simply clicking in the center of that area.

Easy DICOM Viewer will create a polygon of that area of interest for you, instead of you having to manually plot each time of the polygon.

Magnifying an area of interest

Instead of enlarging the entire image, you can choose to magnify only the area of interest.  This lets you concentrate your diagnosis on a specific area while still retaining a context of the overall region.

Anonymize/modify DICOM tag values

You can define tag templates to anonymize/erase/modify groups of DICOM tags, and apply these templates to easily modify the existing values in your DICOM images.  This saves you time from having to repeatedly enter the same values each time you want to modify the tags.

View DICOM tags

Easy DICOM Viewer displays the tag values for all opened images in a spreadsheet-like layout.  This allows you to compare the values of different images easily.

You can also filter the displayed values, helping you to view only the tags you are interested in.

You can export the tag values to Excel when you need to share or work with the values in a different application.  This saves you time from having to copy the values manually, which is prone to errors.

Presenter mode to easily share images

In presenter mode, you can open any of your images and Easy DICOM Viewer will automatically anonymize all sensitive tag values that are displayed in your images.   The DICOM tag values are not modified in any way.  It is only the displayed values that are changed.

This means you no longer need to manually anonymize your images first before using them in a presentation or online screen sharing session, saving you time.

Redact parts of your DICOM images

Easy DICOM Viewer includes a redaction function to black out areas of the image that may be confidential.  You can then export the images with the applied redaction to share with other users.

Convert images to DICOM images

You may sometimes receive medical images that are in a bitmap, jpeg, or png formats, and you need to convert them to DICOM images so that they can be archived in your PACS system.  Easy DICOM Viewer can perform the conversion for you, and at the same time use the tag templates described above to provide some basic values in the new DICOM images.

Burn images to CD/DVD

You can burn the images you are currently studying to a CD/DVD using Easy DICOM Viewer.  The CD/DVD will contain an integrated viewer so your patients can easily open the images themselves without having to download another viewer.  You can also display your company logo/branding within the viewer.

Burning images to CD/DVD using Easy DICOM Viewer

Leave a reply

Easy DICOM Viewer adds the ability to burn your DICOM images to a CD or DVD.  You access this function using the Tools menu item.

If you have a workspace opened, Easy DICOM Viewer gives you the option to use images from that workspace.  You can also just choose other images on your computer.

A lite version of Easy DICOM Viewer is included on the CD/DVD containing your DICOM images.  When started, this viewer will automatically load and display the images that are found on the CD/DVD.

You can choose to display your company logo/brand when the viewer starts up.  Simply select the image to display, and for how long the image should be displayed.

Easy DICOM Viewer then prepares the disc image.  Once prepared, you can then click on the Test button to simulate how the viewer will display your logo (if selected) and how it displays your images.

You can also add additional files into the disc image if required.  Click on the Open folder button to open the staging folder, and copy the required files into that folder and sub-folders.

Next, simply provide the media to write the disc image to, and you’re once.

Using layouts in Easy DICOM Viewer 4

Leave a reply

Easy DICOM Viewer 4 uses a new grid-based layout which offers more flexibility when it comes to displaying your DICOM images.

You can now easily display your DICOM images in a grid using the number of rows and columns that you require:

The above example creates a grid containing 2 rows and 2 columns.

You can then save this layout simply by entering a name for it, and clicking on the Save button e.g.

You can then recall the layout in the future whenever you need to use it.

You can also create layouts with cells than span across multiple rows and columns e.g.

You merge columns and rows by clicking on the Modify layout button and selecting the Merge column and Merge row items.

You can then save these unique layouts and apply them whenever the need arises.

Displaying logical page numbers in search results

Leave a reply

By default, the search results In Easy PDF Search displays the physical page numbers where the search words/phrases are found.

You may sometimes want to display the logical page numbers instead. For e.g. say we have a PDF file that has a cover, followed by a blank page, then 5 pages of prefaces using roman numbering, followed by another blank page, then finally the actual content.

The logical numbering of the PDF would look something like this:

  • cover (physical page 1)
  • blank page (physical page 2)
  • page I (physical page 3)
  • page II (physical page 4)
  • page III (physical page 5)
  • page IV (physical page 6)
  • page V (physical page 7)
  • blank page (physical page 8)
  • page 1 (physical page 9)
  • page 2 (physical page 10)
  • …

In Easy PDF Search 5.2, you can now define the logical page numbering for a PDF file and display that numbering scheme in your search results.  The search results using logical page numbering for the above example will then be displayed this way:

To define the logical page numbering for a PDF file, right click on the PDF file name in the search results and click on the Define logical page numbering item.

In the Logical Page Numbers screen, enter the page count for each page type that have their own numbering scheme or none at all. Using the example above, this is how we would define the logical page numbers.

Adding EXIF data to photos taken using vintage lenses

Leave a reply

I have a collection of Canon and Minolta vintage lenses that I sometimes use with my Samsung NX300/NX500 cameras to achieve that ‘retro’ look.  Obviously, my Samsung cameras are unable to detect the lens details, and hence the EXIF details for focal length, aperture, lens make and model are all empty.

I want to fill in these values so that I can search for these photos later.  So what I do in Easy Photo Search is to first search for photos where the focal length is 0, since this is the value stored in the photos taken using my vintage lenses.

I then choose to export the search results, which contains all photos with a 0 focal length.

In the screen to modify the EXIF values, I enter the relevant details for my vintage lens.

Easy Photo Search then exports the photos with the new EXIF values.

And that’s it – now my photos taken using vintage lenses contain EXIF values which Easy Photo Search can index and search easily, and also displayed in information profiles and overlays.

Search for photos using EXIF data

Leave a reply

Most digital photos contain EXIF information that stores details about the camera and lens settings that were used when the photo was taken e.g. the ISO value, lens focal length, aperture setting etc.

Easy Photo Search is an application that helps you search for your photos based on these EXIF values.  The search screen initially simply looks for all photos.

Say we want to look for photos with an ISO value between 800 and 1600.  We would click on the ISO entry, then select the between ISO option.

We then enter the ISO values, and start the search.

It is that simple.  By default, you can search for photos based on the following EXIF attributes:

  • comment and description
  • lens focal length
  • ISO
  • aperture
  • shutter speed

You can add additional attributes to search by clicking on the Add attribute button.

This expands the search attributes to:

  • camera make
  • camera model
  • date
  • exposure program
  • focal length in 35mm equivalent
  • metering mode
  • GPS location

If you need to search based on other EXIF attributes, drop us a line at support@yohz.com.  We will add additional attributes based on user request.

In Easy Photo Search, the EXIF values for the selected photo is displayed in the Details window on the right, in the Tags tab.

If you chose to display multiple images in different panels, then the EXIF data for all the opened images will be displayed in a tabular form.

This lets you compare EXIF values for different photos easily.

To open multiple images, right click on one of the thumbnails to bring up the context menu, then select the Open images in new panel item.

Now every time you click on a thumbnail, the selected image will be opened in a new panel.

You can also export the EXIF data to an Excel spreadsheet.  Click on the Export images and tags to Excel button to start the export wizard.

Customize the export parameters to your needs.

The Excel spreadsheet is then generated according to your settings e.g.
