Clarification: Software is a collection of instructions which a computer needs to carry out a task. For instance, a tool to edit photos, like Adobe Photoshop, is a kind of software.
A software may be included in some digital cameras. The software that you see on a computer is to complete certain tasks, for example, to edit images or organize digital image files.
Inside a digital camera itself, the instructions to ensure that the unit works correctly are known as firmware, not really a software.
