A Camera is the sweetest and most beautiful person you will ever meet. She knows what's appropriate and when to stop. She lightens up your day like no other. A Camera is a little shortie that you have to look down at, but it just makes her so much more adorable. She has the ability to make you laugh. Her smile is one of a kind. She does the cutest and most random things. When you see her, you just can't help but smile. She brings so much happiness to you, that it's overwhelming. But, she gets annoyed easily and isn't the most confident girl in the world. Compliments can turn her shitty day the whole way around. She has an adorable laugh like no other. She also has eyes that if you look into for too long, that you'll lose track of time. She gets a lot of shit from people that barely know her. She's good at making people think that they don't get to her. But for every mean comment she gets, she falls a little deeper in a hole. But unlike any other girl, she's strong enough to climb her way out within the same day. She's overall the most sweetest and caring person you'll ever meet. If you're lucky enough to know a Camera, then hold onto her. She definitely a keeper.

an apparatus used to take photographs by the admittance of light rays through an aperture. Often using a lens to focus the rays onto a film of light-responsive chemicals.

Dutch slang for cool.

[Sarah]

Any thing usable to capture an image for future viewing.

Today’s smartphones come equipped with a very comprehensive set of camera related specifications. Our smartphone, for many of us, has become our primary camera due to it being the one we always have with us.
In its purest form, smartphone photography is all about collecting photons (light) and converting them into electrons (image). The capabilities of the supporting hardware and software are paramount to producing high-quality images of your chosen subject. Image Signal Processor (ISP)
An equally important part of the smartphone camera experience is the Image Signal Processor (ISP), this is part of the silicon within a smartphones chip-set/CPU and in conjunction with the phones software and OS provides additional enhancements and special effects when both capturing images and to the pictures once captured. These include face detection, filters, panoramic scene capturing and object identification.
Images are also geo-tagged with the GPS coordinates of where the image was captured if the phone has an internal GPS chipset. Quicklinks Camera Index
Our Phone Specification pages have detailed camera specifications and features as shown in the Huawei P20 Pro example below:

The resolution of the image taken by a smartphone is measured in megapixels, a higher megapixel count doesn’t always equate to a better picture. The desire to have more and more megapixels has slowed as manufacturers focus on the quality of those megapixels captured. Accomplished by having larger pixels within the CMOS Sensor to capture more light, contrasting with a high-resolution CMOS sensor that has smaller pixels and therefore captures less light. Higher megapixel images allow ‘cropping’ of the original without losing too much detail. Higher megapixel images also ensure a higher quality image when printed, for example when printing ‘posters.’
As a comparison, when playing back images on a television or monitor - a 4K TV has an 8.3-megapixel count while an HD TV has a 2.1-megapixel number.
In most cases still images are stored either as jpeg or HEVC, these compress the image file size without losing any detail (loss-less compression). Some high-end phones capture in RAW leading to much larger file sizes. The most common format for recording video is H.264/H.265. Google and Apple provide paid ‘cloud’ storage for off-loading your photo’s and video’s over WiFi or cellular to reduce the impact on the phones internal storage.

Aperture
The Aperture of a lens indicates how much light the lens lets in. The larger the aperture, the more light is let in, conversely a smaller aperture lets in less light. Measured in f-stops, these are inverse values, as shown in the aperture chart above, the larger the aperture the lower the f-stop number. An aperture of f/1.4 lets in more light than an aperture of f/8.

Electronic Image Stabilization (EIS) and Optical Image Stabilization (OIS)
Helps eliminate camera shake and produce a better quality image. Some phones successfully use Digital OIS, but the best phones use a mechanical Optical Image Stabilization system.</p>

Autofocus
Modern smartphones have an internal autofocus system, you can’t see this as the external Lens Covers is fixed in place. Only autofocus cameras can allow shooting of really close objects - i.e., macro shooting.
Many smartphones, when zooming in on your subject, use a digital zoom which produces a lower quality image at any given size as it’s effectively ‘cropping’ in for you. However, many flagship smartphones are using a 2nd lens to provide Optical Zoom.
Phase Detection Auto Focus (PDAF)
PDAF Technology uses paired masked pixels on the image sensor, designed to mimic your eyes. The ISP adjusts the camera lenses until both images are synchronized with each other and the subject deemed to be in focus.
PDAF is faster to focus that Contrast Detection Auto Focus (CDAF) and gives a sharper photo.
Laser Autofocus
The camera system is outfitted with a laser transmitter and receiver. The phone uses the time taken for the laser to bounce off its subject to determine the distance to the target.
Good for taking photos quickly and in low light but less useful for landscape photos where the subject is far away from the camera.

Flash Type
A flash will brighten your subject when lighting conditions are poor.
LED flash technology was until recently the most common flash for smartphones. It’s low power, takes up little physical space and can be used continuously. However, it only illuminates a very small area, it’s slow (resulting in blurred fast moving objects), and the color temperature is often ill-suited for a given scene.
For example, an LED flash gives off light roughly at a temperature of 5,500 Kelvin (K) which equates to the temperature of Sunlight. This is why some photos may appear blue when shooting indoors in low light with an LED flash.</p>
To provide a light temperature that better matches the environment some smartphones include multiple LED’s in a flash itself. Each LED produces a different temperature of light, and when combined can create a more natural looking image.

HDR
HDR or High Dynamic Range attempts to add more dynamic range to your photographs.
As opposed to taking one photo, HDR mode takes three photos at different exposures. The CPU/ISP combine these three images together and highlight the best parts of each photo. Often your smartphone can give you the regular photo and the HDR photo. The result should better mirror what you see rather than what your smartphone lens sees.
Check out the comparison shots below to see the starked difference when looking at shadows for example.
Dependent on your subject matter and lighting conditions HDR isnt always the best solution. As such, smartphone manufactures employ AI and Auto HDR to determine the best possible use of HDR and other modes.

Panoramic Photography
A number of steps happen behind the scenes in order for your smartphone to capture a panoramic picture. Firstly, your camera app takes a series of overlapping frames as you pan your phone across the scene or landscape. The individual frames are then stitched together by your CPU/ISP to form the finished Panoramic.
Clearly, its not as simple as described. The CPU/ISP works in conjunction with your smartphones camera AI, gyros, and other features to not only to position each frame within the overall panoramic but also to ensure each frame matches its neighbors exposure, color and so on. All this remarkable trickery ensures the highest quality overall image possible.

Video
The majority of smartphones are capable of capturing 720p HD video 30 frames per second (FPS) as a minimum. The higher the FPS the smoother the video or in the case of slow-motion shooting, the slower you can make a video without losing quality. The higher the resolution and the higher the number of frames the more storage space is required.
