Now no one can deny the fact that iPhone 5S exists in real. Everyday we hear stories about Apple's forthcoming iteration to iPhone. The speculated release date is pegged around September second week followed by retail availability in October 2013. Multiple reports in the past had thoroughly discussed about iPhone 5S design and form factor.
Also, various media channels have confirmed that the next-generation iPhone will boast fingerprint sensor. Recently, a well known Apple analyst predicted that iPhone 5S will come with a 4-inch Retina Display, Apple A7 processor, better camera, a 128GB internal storage and a new color option. Hence, iPhone 5S is portrayed as the next-big thing.
Meanwhile, iPhone 5S is also rumored to have a 12-mega pixel camera with improved image quality and HDR functionality. But till now, nothing concrete is known about iPhone 5S camera. Few details came in when Nowhereelse.fr, published images of camera module used in the next-generation iPhone 5S recemtly. Reportedly, the camera is said to be more powerful with large aperture alongside dual LED Flashlight.
Now GizBot has came across a patent filed by Apple, back in mid 2012. The patent details were published by China Patent Office trademark on its site in early 2013. According to a filing, Apple has developed an image sensor with HDR (High-dynamic-range) imaging. Titled "Image sensor having HDR capture capability," which is more than enough to say that Apple iPhone 5S could boast off an improved camera sensor capable, which could offer brilliant high dynamic range images.
The actual patent abstract from the China Patent Office Trademark reads, "The invention relates to an image sensor having HDR capture capability. A system and a method of generating a high dynamic range image are provided. A single reset of an image sensor may be executed followed by two or more reads of the sensor to retrieve data. These reads of the image sensor may be done prior to a subsequent reset of the sensor. These reads may also be accomplished at predetermined times relative to one another. Data read out during these scans may be deinterleaved by an image signal processor and combined into a high dynamic range image."
Back in April 2013, tinhte.vn published a report saying, "Apple iPhone 5S to have a 12-mega pixel camera with built-in HDR shooting features and a capability to shoot images in low light conditions." The reveal was made to folks over at Tinhte by Wonderful Saigon Electrics (iPhone camera module maker). The above mentioned patent traced by GizBot syncs well with the report by tincht.vn.
We also found another patent filed by Apple on September 2012. Once again, the patent was published by China Patent Trademark Office on April, 2013. Titled "Dynamic Autofocus Operations ", the patent reveals this very feature could be a part of iPhone 5S fantastic camera. So, now it would not be a pain to capture moving birds.
The actual patent abstract from the China Patent Office Trademark read "Systems, methods, and computer readable media for dynamically adjusting an image capture device's autofocus (AF) operation based, at least in part, on the device's orientation are described. In general, information about an image capture device's orientation may be used to either increase the speed or improve the resolution of autofocus operations. More particularly, orientation information such as that available from an accelerometer may be used to reduce the number of lens positions (points-of-interest) used during an autofocus operation, thereby improving the operation's speed. Alternatively, orientation information may be used to reduce the lens' range of motion while maintaining the number of points-of-interest, thereby improving the operation's resolution."
Back in March 2013, Patently Apple discovered two patents published by the US Patent & Trademark Office. Both of the patents were filed by Apple. One among them was titled "Dynamic Autofocus Operations ", while the second patent titled "Partially Lit Sensor". Especially, the second patent revealed a new type of image sensor.
Moreover, GizBot found two more patents published by China Patent Office Trademark. And, again both patents are related to camera module and HDR imaging technique. The first patent is titled "Camera test bench and Camera module ", however, the abstract is not given. The second patent titled "Operating a device to capture high dynamic range images "communicates about High dynamic imaging scene.
