Day 1 of the International Consumer Electronics Show

The International Consumer Electronics Show is underway in Las Vegas, where companies from around the world get to show off the new and exciting technology they’ve been honing over the past year.

Take a look at some of the technological developments that were on display at the first day of the annual show.

LG kicked off the show with a 55-inch television that offers “ultrahigh-definition’’ resolution four times the sharpness of regular HD TV.

The model is the smallest in the company’s 2013 lineup, which includes 65-inch and 84-inch versions.

Qualcomm Inc., a leading maker of chips for cellphones, says it can offer HD cell phone videos with its new Snapdragon 800 chips. The new model has 75 percent more horsepower than Qualcomm’s former fastest model.

At CES, Samsung unveiled new televisions that can be controlled with hand gestures. People will be able to swipe through on-screen menus in a reimagining of the old remote control.

The company said certain high-end Samsung smart TVs sold last year will also be able to be upgraded with the features with an add-on kit.

In addition to Samsung’s products, many of the new “smart’’ televisions are outfitted with speech and motion controls.

In an improvement from the complicated design of former 3-D cameras, Samsung has created a single lens that can go from 2-D to 3-D with the flip of a switch.

Pictured: Michael Abary, senior vice-president for Samsung Electronics America, showed off the new 45mm F/1.8 lens for the NX300 camera, describing it as the world’s first single-lens 3-D system.

With all of the buzz around ultra-HD TVs, one point of interest that’s also been brought up is how to acquire content that lives up to the supremely high resolution.

Sony is taking advantage of being a conglomerate that owns both technology and the media that plays on it by offering a tablet and computer server preloaded with 10 movies with their 84-inch ultra-HD set. The movies, like “The Amazing Spider-Man,’’ come from the Sony Pictures library, or its subsidiary, Columbia Pictures.

The cost of owning the newest technology in the market? A cool $25,000.
