Every year in October, Japan's largest electronics show, Ceatec, showcases all that's new and upcoming from the world's sharpest consumer electronics vendors. Ceatec 2007 brought us some world-first technologies, including a 3mm thick TV, a laptop with super-charged graphics processing and some new high-definition video recorders.

Here are our picks from Ceatec and other new gadgets from the past month:

Incidentally, this year Ceatec hit a major milestone: attendance of more than 200,000 people across its five-day run. Organisers had been looking to break the record for the past three years so it came with more than a little relief that they finally managed it.

Sony 3mm thick OLED TV

Without a doubt the coolest thing at Ceatec this year was Sony's OLED (organic light emitting diode) television. This is something we've been promised all year and the first commercial product doesn't disappoint - except perhaps on price.

The set has an 11in OLED panel and is 3mm thick. OLEDs offer other advantages over LCD and PDP technology, including wider viewing angles, faster response time, and better contrast and colors. However, the technology is difficult to manufacture and the OLED material degrades over time.

Sony said the XEL-1 has a viewing life of 30,000 hours, which allows a user to watch eight hours of television each day for 10 years. The television goes on sale in Japan on December 1, and will cost ¥200,000 (£875). Currently, there are no plans to sell the television outside Japan, as Sony plans to manufacture just 2,000 sets each month.

Here are our picks from Ceatec and other new gadgets from the past month:

Panasonic Blu-ray Disc recorders

Panasonic kicked off Ceatec by unveiling of three new Blu-ray Disc recorders. The recorders can cram up to 18 hours of high-definition video on to a 50GB Blu-ray Disc - something that hasn't been possible until now.

Previous recorders took the MPEG2 digital TV stream as it was transmitted and recorded it directly to disc resulting in a recording capacity of about four hours on the 50GB discs. However the new Panasonic recorders can convert this into the more efficient MPEG4 AVC compression system and thus the greater storage capacity on each disc. They also have built-in hard-disk drives. All three recorders will go on sale in Japan on November 1 with the top-of-the-range BW900 costing ¥300,000 (£1,300).

There are no immediate plans to sell them overseas but Panasonic said it is examining the possibility.

Here are our picks from Ceatec and other new gadgets from the past month:

Toshiba SpursEngine laptops

One of the cool gadgets being demonstrated by Toshiba was a prototype Qosmio laptop that includes a multimedia co-processor, called SpursEngine, based on the Cell Broadband Engine processor core. It's based on the same processor core found in the PlayStation 3 and aims to provide better video-processing capabilities for computers.

One laptop offered facial-recognition capabilities that find a user's face, and then allow virtual makeup and different hairstyles to be applied and viewed in three dimensions. A second demonstration used the SpursEngine to search a video, and then break the video clip into scenes based on facial expressions, allowing a user to find a particular scene more easily. Toshiba has yet to finalize plans to commercialize SpursEngine.

Here are our picks from Ceatec and other new gadgets from the past month:

Omron Okao Vision

While not strictly a gadget, Omron's Okao Vision is a software application that could certainly make other gadgets cool!

A new addition to the facial-recognition family finds a face in a video image and then provides an estimation of how much a person is smiling (from 0 to 100 percent). The technology could be used, for example, in a digital camera to sense when photo subjects are smiling and ready for their picture to be taken.

Sony's recently launched DSC-T200 has just such a feature - branded Smile Shutter by Sony - but it's not based on the Omron system. Omron hopes to find customers for the software this year.

Sharp LCD with optical scanner

If you think the iPhone screen's two-finger touch is cool then Sharp has something for you! The company showed a prototype 3.5in screen integrates an optical scanner pixel alongside each LCD pixel.

This means the screen can scan objects such as name cards placed on its surface and recognise fingers or other objects. Because it's determining the position of fingers from a scanner input and not a touchscreen, it's possible to touch the screen in more than two places and have all fingers recognised. The panel is still a prototype but commercialisation is expected in the first half of next year. Samples are already in the hands of potential customers but Sharp wouldn't name those companies.

Whoever they are, you can be sure some are trying to outdo Apple's iPhone!

Samsung music phones

Away from Ceatec, Samsung unveiled a refreshed line-up of three new cell phones that are targeted at music lovers. The top-of-the-range SGH-i450 boasts an amplifier developed by high-end audio specialists Bang & Olufsen and runs the Symbian S60 smartphone software platform. It has a 2.4in display and a 2Mp camera. It works on WCDMA (wideband code division multiple access) networks and supports HSDPA (high-speed downlink packet access) data service up to 3.6M bps (bits per second).

The phone will first appear in Italy at the end of October and will follow in other European countries. It will cost about €360 (£250) before carrier subsidies. One weak point of the handset is the amount of built-in memory, which is just 35MB. That's about enough for 7 to 10 songs, which is disappointing for a music phone. Memory can be expanded up to 4GB with a Micro SD memory card.

Sony Video Walkman with TV

Sony is adding mobile digital TV viewing and recording to the video Walkman it sells in Japan. The "OneSeg" system, as it is marketed, has proved a popular addition to many portable gadgets and can now be found on many high-end mobile phones, laptop PCs, car navigation systems and even electronic dictionaries.

The only difference between the three new Walkman devices with TV is their memory capacity. The NW-A916 has 4GB of memory, the NW-A918 has 8GB and the NW-A919 16GB. Compared to the most recent players the screen size has been increased to 2.4in from 2in. They'll go on sale in November in Japan only. The NW-A916 will cost about ¥30,000 (£130), the NW-A918 ¥35,000 and the NW-A919 ¥45,000.
