Figure 4 Complete Image on a 5 inch x 3 inch screen Figure 5 Subset of Complete Image Future of PDA screen resolutions It is debatable how fast the screen resolution of the Palm VII will improve. Therefore, the technology is already there. However, it is believed that Palm made a conscious decision to make the Palm VII more like mobile phones. Most mobile phones only have black and white colors. The benefits of fewer colors include simpler screen displays and faster download times.
Conclusions There are many computer processes that have been automated.
For instance, as discussed above, the conversion of JPG to WBMP can be automated. However, for image display on a Palm VII there needs to be much human decision making in the process of creating the image. In this way, the scientist can better control what is displayed by the four colors. Unsupervised classification does a reasonable job classifying the image into four colors. However, a human needs to decide what the produced classes mean.
