By the way, some cameras do run linux, and they take 5-15 seconds to start up. If a camera does take long to startup, it is because it's running linux. These are typically security cameras, which are switched on basically only once, or as a periodic power cycle. Consumer cameras always use a RTOS. Ambarella makes chips for both cases. for example the H2 is for linux, while the S5 is the same chip but for RTOS.

- chiph 9y agoMy first digital camera was a Kodak DC220 [0] and it ran the Digita operating system. [1] Boot time was in the 20-30 seconds (good for the time) but you would often miss shots. "Spontaneity" wasn't in it's vocabulary. Photos were surprisingly good for a 1 megapixel camera with fixed-focus.
