When flicking through photos, pictures appear to move. Why and how?

[Akagi]

Hi guys, I have always wondered this. When I flick through pictures I have taken with some form of digital camera such as a compact or a cameraphone, when I flick through them on the device or on my PC, its almost as though another frame is present.

It quickly flicks past what would be a frame later if it were a video in a fraction of a second before the picture loads. If you blink you would miss it, and you have to flick between a few photo's several times before you figure out what is happening.

It is only really apparent in shots where something is moving.

Why does this happen?

Nah its different to that, for example if I were to take a picture of moving traffic, in the 'split second frame' the traffic will have moved further. Or if I were to take a picture of someone turning around, in the 'split second frame' they would have turned further.

It's very strange

It's called "Shutter Lag", it's normal on cheap cameras

Thanks. I'm not going to deny that my camera(s) are cheap. Hell, the camera on my phone is better than my compact.

Will get an SLR when I can afford it, don't worry
