he right to downsize the image. These online albums provide some fairly simple image-editing capabilities such as cropping and red-eye removal. Snapfish also provide some autocorrection including autocontrast. Both also provide view/review and share facilities. Companies such as Scalado7 and Shutter Fly8 provide similar capabilities though optimised for camera-phone applications supported via cellular network operators and integrated with existing MMS server topologies. Just as camera phones have to at least aspire to have equivalent functionality to digital cameras, SO these network-operator-specific service offerings have to be at least as good as existing and competitive online services. This is a challenge, particularly when competitive online services are free. 8.7 Summary User expectations of camera-phone image quality and functionality are influenced by the performance now available from entry-level and midtier digital cameras. Optical quality is a function of lens quality, sensor quality and the effectiveness of the algorithms used to correct for optical and processing impairments. Functionality includes capabilities such as autofocusing and autoexposure. The accuracy and speed with which these functions are performed provide differentiation between low-end and high-end products. Camera phones have at least to aspire to providing quality and functionality that is equivalent to similarly priced digital camera products. This can only be achieved through subsidy or by producing products in much higher volumes. There are also fundamental form-factor and power-budget issues to address. The user experience is also determined by how images are stored and managed in the network and whether the quality of the original image is preserved. In terms of image editing, cataloguing and management functionality, user expectations are increasingly dictated by the 4 http://www.opera.com/. 5 http://www.kodakgallery.com/gallery/welcome.jsp 6 http://www2.snapfish.co.uk/snapfishuk/welcome. 7 www.scalado.com. 8 www.shutterfly.c
