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.

Google has indexed invite links to private WhatsApp group chats, meaning anyone can join various private chat groups (including several porn-sharing groups) with a simple search.

According to a report in Motherboard, invitations to WhatsApp group chats were being indexed by Google.

The team found private groups using specific Google searches and even joined a group intended for NGOs accredited by the UN and had access to all the participants and their phone numbers.

Journalist Jordan Wildon said on Twitter that he discovered that WhatsApp's "Invite to Group Link" feature lets Google index groups, making them available across the internet since the links are being shared outside of WhatsApp's secure private messaging service.

"Your WhatsApp groups may not be as secure as you think they are," Wildon tweeted on Friday, adding that using particular Google searches, people can discover links to the chats.

According to app reverse-engineer Jane Wong, Google has around 470,000 results for a simple search of "chat.whatsapp.com", part of the URL that makes up invites to WhatsApp groups.

WhatsApp spokesperson Alison Bonny said: "Like all content that is shared in searchable public channels, invite links that are posted publicly on the internet can be found by other WhatsApp users."

"The links that users wish to share privately with people they know and trust should not be posted on a publicly accessible website," Bonny told The Verge.

Danny Sullivan, Google's public search liaison, tweeted: "Search engines like Google & others list pages from the open web. That's what's happening here. It's no different than any case where a site allows URLs to be publicly listed. We do offer tools allowing sites to block content being listed in our results."

Bengaluru, Jan 17: India’s latest communication satellite GSAT-30 was successfully launched from the Spaceport in French Guiana during the early hours on Friday.

In a press release, ISRO, has stated that the launch vehicle 'Ariane-5 VA-251' was blasted off from Kourou Launch Base, French Ginana at 0230 hours, carrying India’s GSA-30 and EUTELSAT KONNECT for Eutelasat, as per schedule.

The Ariane 5 upper stage in an elliptical Geosynchronous Transfer Orbit.

With a lift-off mass of 3,357 kg, GSAT-30 will provide continuity to operational services on some of the in-orbit satellites.

GSAT-30 derives its heritage from ISRO’s earlier INSAT/GSAT satellite series and will replace INSAT-4A in orbit.

“GSAT-30 has a unique configuration of providing flexible frequency segments and flexible coverage. The satellite will provide communication services to Indian mainland and islands through Ku-band and wide coverage covering Gulf countries, a large number of Asian countries and Australia through C-band," ISRO Chairman Dr K Sivan said.

Dr Sivan also said that “GSAT-30 will provide DTH Television Services, connectivity to VSATs for ATM, Stock-exchange, Television uplinking and teleport Services, Digital Satellite News Gathering (DSNG) and e-governance applications. The satellite will also be used for bulk data transfer for a host of emerging telecommunication applications.”

ISRO’s Master Control Facility (MCF) at Hassan in Karnataka took over the command and control of GSAT-30 immediately after its separation from the launch vehicle. Preliminary health checks of the satellite revealed its normal health.

In the days ahead, orbit-raising maneuvers will be performed to place the satellite in Geostationary Orbit (36,000 km above the equator) by using its onboard propulsion system.

During the final stages of its orbit raising operations, the two solar arrays and the antenna reflectors of GSAT-30 will be deployed. Following this, the satellite will be put in its final orbital configuration.

The satellite will be operational after the successful completion of all in-orbit tests.
