Late last year Hewlett Packard announced that it was exiting the digital camera market, citing a lack of growth in that business sector. But just because HP has quit the camera business doesn’t mean it’s abandoning all of its digital camera technologies; the image processing algorithms originally developed for HP’s digital cameras will now be incorporated into cell phones, enabling users to create high-quality prints from pictures taken with camera phones.
HP has provided a license of its image processing algorithms—which include, for example, red-eye processing, subtle lighting adjustment, and color correction—to Flextronics, a company that makes electronics modules for cell phones. Flextronics’ modules incorporate HP’s algorithms, and in return, HP receives royalties.
Based on the demo given at the Mobile World Congress, the resulting hardware/software solution can generate high-quality images out of relatively mediocre optics and image sensors. At the demo HP showed some stunning 8x10 prints made from pictures taken with an image sensor module that’s used in cell phones. (HP has posted before-and-after images on its website, at http://www.hp.com/hpinfo/abouthp/iplicensing/nr_flextronics_images.html)
This is a classic application of digital signal processing—substituting algorithms and compute power for high-quality hardware. With enough compute power and some excellent algorithms, it’s possible to compensate for many shortcomings in the hardware (in this case, the image sensor and optics). All of which raises the question, are camera phones on the verge of subsuming a big chunk of the digital camera market?
According to Brian Carlson, Strategic Marketing Manager for Texas Instruments’ Wireless Terminals Business Unit, that’s exactly what’s happening. “The gap between digital cameras and camera phones is closing quickly, starting from high-end phones and moving into mid-range phones over the next few years,” Carlson says. “Right now, it’s all about meeting customer expectations from digital cameras and camcorders—you can expect to see features like image stabilization, face tracking, and slow-motion capture coming to camera phones in the near future.”
In fact, it’s likely that cell phones will not only subsume a significant portion of the digital camera market, but many other classes of consumer electronics products as well—including portable media players, portable gaming consoles, etc. Increasingly, previously standalone products (like digital cameras) will become features of other products (like cell phones). When that happens, it’s typically the algorithms that maintain their value, rather than the hardware. As a result, HP’s investment in image processing algorithms for its digital cameras will continue to pay off—even without HP cameras to put them in.
