The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
By 2011, cell phones with an integrated camera were selling hundreds of millions per year, which were causing a decline in digital cameras. In 2015, digital camera sales were 35 million units or only less than a third of digital camera sales numbers at their peak and also slightly less than film camera sold number at their peak.

Samsung NX500 - Same 28 MP APS-C sensor as NXI but 4K video is not downsampled from 6.5K so less details and more noise than the NX1 - with this 2.4× crop factor the kit lens become a 38–120mm f8.5–13.4 equivalent for depth of field; 15 min max recording time limit
Panasonic Lumix CM1. This is a list of smartphones with a primary camera that uses a 1.0-type (“1-inch”) image sensor or larger. However, as of February 2024, there are no smartphones that use a sensor larger than 1.0-type.
11: The Galaxy Z Flip's ultra-wide camera utilizes the 16 Mp sensor, but images are cropped down to 12 Mp. 12: The Galaxy S21 and S21+ utilizes either one of two sensors: the Samsung 2LD (Exynos variant) or the Sony IMX555 (Snapdragon variant). [70] They are regarded as nearly identical sensors.
An image of N pixels height by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as "resolution", the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and ...
This makes them more efficient than FR models at the expense of lower accuracy. No-Reference Methods (NR): NR models try to assess the quality of a distorted video without any reference to the original signal. Due to the absence of an original signal, they may be less accurate than FR or RR approaches but are more efficient to compute.
These techniques, along with several others, help H.264 to perform significantly better than any prior standard under a wide variety of circumstances in a wide variety of application environments. H.264 can often perform radically better than MPEG-2 video—typically obtaining the same quality at half of the bit rate or less, especially on high ...
