There are just four days left until Apple's 10 September event, which means this is the last Friday leaked images round-up before the truth is revealed by the company itself.

Surprisingly, there haven't been as many leaked images as in previous weeks this week, but we've still got an alleged iPhone 5S fingerprint sensor and an iPad 5 vs iPad 4 comparison video to show you.

iPhone 5S fingerprint sensor

This week there have been two leaks of the iPhone 5S's rumoured fingerprint sensor, which is expected to be built-in to the Home button for more secure mobile payments.

The first photograph came from on Tuesday, and shows a part that could be the iPhone 5S's fingerprint sensor. The image show the iPhone 5 Home button and an earlier iPhone 5S home button leak alongside the new leak, which has a more complex design.

A later report from Sonny Dickson added credibility to the earlier leaks because it contained photographs of what looks like the same iPhone 5S Home button component.

Analyst Maynard Um from Wells Fargo on Wednesday boosted his price range for Apple stocks based on the expectation that the iPhone 5S will have a fingerprint sensor, and says that the new feature could encourage consumer and corporate markets to adopt Apple's smartphone.

iPad 5 casing and digitiser video

A video uploaded to YouTube on Tuesday shows what is claimed to be the front digitizer and the rear casing of Apple's next-generation iPad, dubbed iPad 5.

The video offers a closer look at how the iPad 5 could compare to its predecessor.

The iPad 5 is expected to have a slimmer, lighter design with thinner side bezels and a look that more closely resembles the iPad mini.

We don't expect to see the iPad 5 launch at Apple's 10 September event. It's more likely that the iPad 5 will be unveiled at a separate event in October, alongside a new iPad mini.

KGI Securities analyst Ming-Chi Kuo has predicted that Apple will start shipping parts for the two new iPads late in the third quarter of the year.
