Canon: Major Possibilities in Smartphone Segment But Quality is Supreme

According to Mizoguchi, "unless we have a comprehensive imaging system ready for smartphones that provides a high-level experience to users as they have with our cameras, we will not go ahead for the smartphone camera market"

DSLR leader Canon brings its first mirrorless camera to India.

At a time when smartphone makers are looking at camera giants to help them add top-of-the-line functionalities to enhance user experiences, Japanese major Canon on Wednesday said possibilities are there in the growing smartphone segment but the company cannot compromise with quality and standards.

According to senior Canon executives, discussions are currently on at the Internal levels but they are not yet convinced at delivering perfect smartphone camera experience, the way they have achieved with ‘true’ cameras.

“I do not deny the possibility when it comes to making lens for smartphones. However, a true and complete camera experience is core to our philosophy. We provide state-of-the-art ecosystem – lens, camera and processor — and not just one component,” Naoya Kaneda, Advisory Director, Group Executive, ICB Optical Business Group, Image Communication Business Operations, Canon, told IANS.

“We maintain very high standards when it comes to cameras and unless we achieve that for smartphones we will not enter that segment,” Kaneda added during a media roundtable at Canon’s headquarters here.

According to Yoshiyuki Mizoguchi, Group Executive, ICB Products Group, Imaging Communications Business Operations, Canon, they have been exploring the possibility of delivering a lens system for smartphones.

“However, we can’t compromise on our camera legacy. Camera has always been centric to us,” Mizoguchi added.

An early innovator in smartphone camera technology, Chinese smartphone maker Huawei has brought a Leica-designed, tri-camera system to the device, which is its USP.

Huawei P20 Pro is the world’s first smartphone to feature a triple camera system from Leica, the German camera maker.

The rear camera system has a primary 40MP RGB sensor, a 20MP monochrome sensor and an 8MP sensor with telephoto lens.

All three lenses use the same optical image stablisation (OIS) technology, thus ensuring clearer shots.

According to Mizoguchi, “unless we have a comprehensive imaging system ready for smartphones that provides a high-level experience to users as they have with our cameras, we will not go ahead for the smartphone camera market”. (IANS)

Usage of Smartphones for Eye Check-up May Lead to Misdiagnosis

However, when the images were calibrated, the differences between lighting levels and camera types were significantly minimalised - with differences between smartphones reduced by approximately 30 per cent

Using smartphones to capture photographs of patients’ eyes for check-up may lead to misdiagnosis as camera colour sensors vary and as a result, images of the same eye may appear different depending on the model of smartphone used, warn researchers.

The study, published in the journal Scientific Reports, suggests that calibration of phone cameras is vital to capture accurate data.

Eye examinations to look for redness in the eye can indicate a variety of conditions including conjunctivitis, dry-eye disease and tear-gland dysfunction.

Clinicians increasingly use smartphones in conjunction with ophthalmic imaging equipment, such as the eyepiece of a slit lamp, because of their portability, ease of use and relatively low cost.

The connectivity also allows for upload to the Cloud, which is useful for telemedicine – the remote diagnosis and treatment of patients using telecommunications technology – and Artificial Intelligence applications that store thousands of images from different institutions.

However, the autofocus algorithms and hardware specifications of cameras may be different for different manufacturers which means different cameras can produce different results for the same scene.

“It is important that clinicians bear this in mind,” said lead study author Carles Otero from Anglia Ruskin University in England.

For the study, the researchers took 192 images of eyes using three smartphone cameras, two different lighting levels and two zoom levels.

The images were duplicated and one set was white balanced and colour corrected (calibrated) and the other left unaltered.

The researchers took photographs in autofocus mode with the iPhone 6s, the Google Nexus 6p and the Bq Aquaris U Lite, and found that the iPhone results were significantly different from the other two devices, when computing relative redness of each eye, and when compared to a clinician’s diagnosis.

However, when the images were calibrated, the differences between lighting levels and camera types were significantly minimalised – with differences between smartphones reduced by approximately 30 per cent.

“Our results show that while the clinician’s subjective evaluation was not affected by different cameras, lighting conditions or optical magnifications, calibration of a smartphone’s camera is essential when extracting objective data from images,” Otero said. (IANS)
