mpacts generally have better resolution, image stabilisers and longer-range zooms, they do not have the speed, viewing systems or ultimate image quality of their digital SLR equivalents. The above examples also illustrate how high-end product features migrate towards low-end products over time just like the car industry and/or mobile phones where smart-phone functions migrate over time towards lower-end products. Self-evidently, it is not practical to replicate the optical quality and functionality packaged in a 600-g digital camera in a 100-g cellular phone. However, users of digital cameras don't necessarily understand this and we cannot expect consumers to be particularly sympathetic to the cost and size and power budget constraints implicit in cellular phone design. All they will say is this phone doesn't take good pictures. Having said that, a modern smart phone generally produces some pretty impressive results. 8.5 Camera-Phone Network Hardware Even SO. it is sensible to concentrate on some of the other user benefits that come from packaging phones with cameras. Optical quality and functionality are not just a function of the digital camera or camera phone but a composite of the components used to store, process and handle images once they leave the users device. Image stores, image servers and the way in which imaging storage is realised in hardware are all part of the 'quality and value' process. For imaging, the amount of storage needed is partly driven by how often users take pictures but also by the imaging bandwidth. Given that high-end cameras are now capable of capturing 40-megapixel images, it seems churlish not to provide an equivalent increase in storage capability. Imaging bandwidth directly determines the amount of storage needed. Note we cannot automatically expect users to downgrade a RAW or TIFF image to a JPEG just for our convenience. What's the point of having a decent camera capability if you the throw 90% of the image in the bin. Other metrics include the time it takes to upload and dow
