Example of frame sizes with VB-C50i*
This is true for the VB-C50i and VB-C50FSi.
The following tables give some typical frame sizes (in kilobytes) for various quality and
resolution values from a VB-C300 and VB-C50i. However it is important to note that,
depending on the complexity of the image, the frame sizes may vary substantially from
those listed in the tables. For example, images of an empty corridor would typically be
smaller than these values and images of a very intricate pattern such as a crowded
shopping mall would typically be larger than these.
