New Photo Enlargement Software Gives Cell Phone Photos Better PrintResults
San Diego, CA (PRWEB) April 19, 2005 -- A new technology has just been
released called Imagener that enlarges pictures without loss of image quality. Cell phone photos often do not have enough resolution to deliver acceptable printout results. Cell phone cameras tend to make images at 160 pixels per inch, while the acceptable resolution for printing is in the 300 dpi range. Kneson Software (kneson.com) has developed new photo software technology that extends current enlargement techniques to analyze more of the image and give mobile phone photos new life. Limited technology exists to enlarge cell phone photos to print quality. Most commercial programs use a technique called bicubic interpolation to figure out how to add pixels that will increase resolution. Bicubic compares immediately adjacent pixels to the one being enlarged which starts to show those blocky squares above 200% enlargement. Even the most expensive commercial programs do not have enlargement capabilities beyond this bicubic method. Imagener’s "Progressive++" technology analyzes pixels well removed from each targeted pixel and then estimates how colors change based on overall image patterns. This fills in areas with pixel colors based on much more image information than current enlargement methods, and enlarges cell phone photos to printable quality. “Before now there was really no way to get cell phone snapshots into frames and up on the wall,” said Donald Henderson, president of Kneson Software. “You can enlarge in small increments in the high priced commercial photo software packages, but results are often not sufficient for printing. Another option is to take the digital file to a photo kiosk for printing, but these also use bicubic enlargement methods.” Improvements in enlargement methods have lagged behind other digital image technology developments. Today, the advent of evolved object-oriented computer programming languages like C++ has allowed the development of much more sophisticated means of enlarging digital images like those from cell phones. Products like Imagener extend the usefulness of cell phone photos closer to images from traditional and multi-megapixel digital cameras.

Even the free Irfanview provides Lanczos interpolation. Lanczos is a type of windowed-sinc interpolation that can be scaled to *any* size of kernel, looking at an arbitrarily large number of input pixels for each output pixel. (Though Irfanview itself doesn't let you choose the size, it's got to be larger than the 4x4 input samples used by bicubic). But even the best interpolation methods only do a better job of preserving detail. A 640x480 pixel image doesn't have much detail period. In the case of my cellphone camera, it also has colour moire and other artifacts I'd rather *not* preserve faithfully. I'm sure the paragraphs above were written by a marketing person who went to the company engineers, said "tell me how our method is better than what already exists", came away with a very limited knowledge of interpolation, and then extrapolated from that. Hey - the marketing copy is *better* than the truth. About Kneson Software Kneson Software is a software manufacturing and marketing company with over 15 years experience in perfectly matching identified customer needs with world-class software development. Kneson Software develops all of its products using pure C/C++, programmed by developers that have used C++ since its earliest days of existence. This is utterly useless information. An interpolation algorithm is a mathematical method, and will give the same output (if implemented carefully) whether you write in assembler, Basic, Fortran, C++, or anything else. Besides, using C++ for software development is not exactly notable these days. You can read more about Kneson Software at kneson.com. I see no point in doing so. Dave |
