Camera megapixel war in smartphones: Picture perfect or just a gimmick?

In 2012, Nokia, which was at the top of the mobile industry, brought 808 PureView, a Symbian operating system (OS)-based smartphone with an insane 41MP camera that created quite a buzz.

Since then, Android-based smartphones started gaining traction and original equipment manufacturers (OEMs) began adding more megapixels to the cameras to lure the crowd.

Now Chinese smartphone makers have sounded the bugle for a megapixel war and the users are in for some sweet deals as camera sensors grow in specifications at affordable price points.

In India, Realme, which initially started off as a subsidiary of Chinese handset maker OPPO, became the first to introduce a 64MP camera smartphone -- Realme XT -- few weeks ago followed by Xiaomi, which has recently unveiled its Redmi Note 8 Pro with 64MP.

Samsung has even created a 108MP sensor for upcoming smartphones.

As many as 50 per cent of smartphones sold globally will have three or more camera sensors by the end of 2021, says Counterpoint Research.

According to industry experts, it is an attempt by the brands to differentiate themselves from competition and remain at the top of the consumers' mindshare.

"It should be seen as a marketing plank, which enables brands to showcase innovation for a feature which is important for smartphone consumers these days," Navkendar Singh, Research Director-Devices and Ecosystem, India & South Asia, International Data Corporation (IDC) told IANS.

These numbers indicate the availability of the sensor size at a cost that can let smartphone brands bring it in a model at affordable price points.

"In early 2020, we should expect launches with 92MP and 108MP in the market. Beyond a certain megapixel capability, a normal consumer cannot feel the difference in the photograph purely from a megapixel viewpoint," Singh noted.

According to Counterpoint Research, Xiaomi was at the second spot with a 17 per cent share in the Rs 15,001-Rs 20,000 price segment in India in Q2 2019, while Realme ranked sixth with 6 per cent share in the same period.

However, Realme inched up to the fourth position with 12 per cent market share, whereas Xiaomi slipped to the fifth spot with a share of 9 per cent in July-August.

"In Q2 2019, 14 per cent smartphones shipped with 48MP lens cameras and 70 per cent with two or more rear cameras.

"However, merely adding a bigger megapixel sensor does not determine higher picture quality," Karn Chauhan, Research Analyst at Counterpoint Research told IANS.

There are multiple factors, such as the lens, the size of the aperture, Image Signal Processor (ISP), software algorithms, AI, etc. which come into play while determining the quality of the picture.

"The tech advancements, exemplified by Samsung eISOCELL Bright GW1', the 64MP image sensor, used by the likes of Realme and Xiaomi, are essentially pushing the envelope for better, low light HDR photography and brighter, detailed photographs mimicking very closely the human eye vision," Prabhu Ram, Head, Industry Intelligence Group (IIG), CMR, told media.

Cybersecurity researchers on Monday warned of a Trojan malware campaign which is targeting India's co-operative banks using COVID-19 as a bait.

Seqrite, the enterprise arm of IT security firm Quick Heal Technologies, detected the new wave of Adwind Java Remote Access Trojan (RAT) campaign.

Researchers at Seqrite warned that if attackers are successful, they can take over the victim's device to steal sensitive data like SWIFT logins and customer details and move laterally to launch large scale cyberattacks and financial frauds.

According to the researchers, the Java RAT campaign starts with a spear-phishing email which claims to have originated from either the Reserve Bank of India or a nationalised bank.

The content of the email refers to COVID-19 guidelines or a financial transaction, with detailed information in an attachment, which is a zip file containing a JAR based malware.

Upon further investigation, researchers at Seqrite found that the JAR based malware is a Remote Access Trojan that can run on any machine which has Java runtime enabled and hence it can impact a variety of endpoints, irrespective of their base operating system.

Once the RAT is installed, the attacker can take over the victim's device, send commands from a remote machine, and spread laterally in the network.

In addition, this malware can also log keystrokes, capture screenshots, download additional payloads, and extract sensitive user information, Seqrite said, adding that such attack campaigns can effectively jeopardise the privacy and security of sensitive data at the co-operative banks and result in large scale attacks and financial frauds.

To prevent such attacks, users need to exercise ample caution and avoid opening attachments and clicking on web links in unsolicited emails.

Banks should also keep their operating systems updated and have a full-fledged security solution installed on all the devices, Seqrite advised.

Washington, Jan 7: Facebook will ban deepfake videos ahead of the US elections but the new policy will still allow heavily edited clips so long as they are parody or satire, the social media giant said Tuesday.

Deepfake videos are hyper-realistic doctored clips made using artificial intelligence or programs that have been designed to accurately fake real human movements.

In a blog published following a Washington Post report, Facebook said it would begin removing clips that were edited--beyond for clarity and quality--in ways that "aren't apparent to an average person" and could mislead people.

Clips would be removed if they were "the product of artificial intelligence or machine learning that merges, replaces or superimposes content onto a video, making it appear to be authentic," the statement from Facebook vice-president Monika Bickert said.

However, the statement added: "This policy does not extend to content that is parody or satire, or video that has been edited solely to omit or change the order of words."

US media noted the new guidelines would not cover videos such as the 2019 viral clip -- which was not a deepfake -- of House Speaker Nancy Pelosi that appeared to show her slurring her words.

Facebook also gave no indication on the number of people assigned to identify and take down the offending videos, but said videos failing to meet its usual guidelines would be removed, and those flagged clips would be reviewed by teams of third-party fact-checkers -- among them AFP.

The news agency has been paid by the social media giant to fact-check posts across 30 countries and 10 languages as part of a program starting in December 2016, and including more than 60 organisations.

Content labeled "false" is not always removed from newsfeeds but is downgraded so fewer people see it -- alongside a warning explaining why the post is misleading.

New Delhi, Jul 13: The Telecom Regulatory Authority of India (TRAI) has blocked Bharti Airtel's Platinum and Vodafone Idea's RedX premium plans that offer faster data speeds and priority services to customers as both the plans were violating net neutrality norms.

The telecom watchdog has asked Bharti Airtel to explain within seven days how such a similar plan being launched does not violate the rules of net neutrality.

Vodafone Idea's RedX plan has been in the market since November 2019. They made some modifications in May 2020 and the Bharti Airtel was soon going to launch a similar plan.

According to TRAI, the higher speed for premium customers discriminate against others and violates net neutrality.

Responding to TRAI's move, Airtel spokesperson said: "We are passionate about delivering the best network and service experience to all our customers. This is why we have a relentless obsession to eliminate faults and have been consistently recognised by international agencies as the best network in terms of speed, latency and video experience."

"At the same time, we want to keep raising the bar for our post-paid customers in terms of service and responsiveness. This is an ongoing effort at our end," the spokesperson said.
