What means the sharpness and clarity of an image?
In practical terms, resolution describes the sharpness, or clarity, of an image or picture. It is expressed in terms of the number of pixels that can be displayed both horizontally and vertically. Resolution is an important factor to measure the visual quality of digital images, photos and videos.
Sharpness is when fine details are clear and distinct (think of a close-up shot of fine watch or crisp landscape). Lens quality, shutter speed, camera stability, and focus are critical to capturing sharp images.
Clarity adjusts the contrast within the details of your image, without affecting the overall tone of the image. As you adjust Clarity, the details are either clarified or smoothened, but the whites and blacks remain unaffected, and sharp edges remain sharp.
Clarity is a local contrast increase that focuses on the mi-tones of the image. If differs from sharpness, because whereas increasing sharpness increases the contrast between dark and light tones, clarity increases the contrast within the middle tones of the image.
Sharpness is the level of the clarity of detail in a photo and is a valuable tool for emphasizing textures of subjects and subjects' details in an image. The sharpness of an image is described by two main factors: resolution and acutance.
If you want to improve the quality of a photo, try sharpening it. Use an unblur tool to get rid of fuzzy photos and get crisp details. Choose your image, click Edit Image, and under Adjust, move the Blur and Clarity sliders until you're satisfied and ready to share it.
Comparing restoration results requires a measure of image quality. Two commonly used measures are Mean-Squared Error and Peak Signal-to-Noise Ratio .
Image quality can be assessed using two methods: subjective and objective. Subjective methods are based on the perceptual assessment of a human viewer about the attributes of an image or set of images, while objective methods are based on computational models that can predict perceptual image quality.
Resolution refers to the amount of pixels or lines that your camera can capture per inch or per degree. It determines how much detail and information your image can contain. Sharpness refers to the contrast and clarity of the edges and contours in your image.
The sharpness of a digital image refers to the degree of clarity in both coarse and fine specimen detail. A lack of sharpness in digital images captured with the microscope often results from poor focus adjustment, vibration, or the specimen not being flat with respect to the imaging plane.
Does sharpness affect image quality?
Sharpness is one of the most important image quality attributes for a camera. Often, the sharpness and resolution of a camera system are confused and used interchangeably. In this post, I hope to sort out some of the confusion.
Aperture The aperture of your lens has a definite effect on image sharpness. Each lens has a “sweet spot” aperture that provides maximum sharpness. This is, generally, two or three stops from the lens's widest aperture. Therefore, an f/2.8 lens will have a sweet spot around f/5.6 or f/8.
resolution. The clarity or sharpness of an image.
For example, the size of the imaging sensor in a digital camera affects the range of the lens, as well as the field of view (size of area captured). In addition, the file format used in the camera to store images can negatively affect image quality and clarity.
Sharpness is characterized by its edges, while clarity suggests a lack of haze.

For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image. In effect, spatial resolution refers to the number of independent pixel values per unit length. The spatial resolution of consumer displays ranges from 50 to 800 pixel lines per inch.
With most TVs, it actually masks fine detail. That means when your sharpness is set too high, you could lose some of the crisp detail possible on that new TV. In some cases, the best sharpness setting is actually zero, while on most TVs the setting is best in the bottom 20% or so.
In general, a higher sharpness setting will make the image look sharper, but it can also make the image look more grainy or artificial. If you are playing a game that requires you to be able to see small details, such as a shooter or a strategy game, then a higher sharpness setting may be helpful.
What is the best setting for image quality?
- Aperture: f/1.8-f/5.6 in low light or for a narrower depth of field, and f/8-f/16 for a wider DoF.
- Shutter Speed: From 30 seconds to 1/4000th of a second depending on the scene.
- ISO: 100-3200 in entry-level cameras, and 100-6400 in more advanced cameras.
Sharpness: Set at 0%
Of course, you want the images on your TV to be sharp, but most movies and TV shows are already sharp enough. So, you want to set the sharpness value to be fairly low. Depending on what TV you have, you should set your sharpness to 0% or anything under 50%.
We suggest you turn the sharpness control down to zero, then add sharpness sparingly only if the image looks soft, with poorly defined edges. Also turn off any noise-reduction and image-enhancement or “dynamic” modes; these tend to reduce image quality.

Resolution and sharpness are two different beasts. Sharpness can be subjective and the perception of sharpness is influenced by a handful of factors like aperture, depth of field, shutter speed, lens resolution, and camera sensors. It has a lot to do with contrast too, especially along the edges of objects in a frame.
Sharpness is quite difficult to define precisely because it's based on subjective evaluations, which are influenced by the contrast along edges in a photo. This characteristic is known as 'acutance'. We judge an image to be sharp when the edge contrast differences we see are relatively large.
Sharpening can help make it look crisp and clear by enhancing the edges of objects in the image. However, adding too much sharpness can actually make an image look worse, or it can lead to a loss in image detail. As you can see, the right amount of sharpness makes the photo look crisp.
So you want the sharpest area in the image to be the most important area in the image. If the whole photo is slightly soft, but the subject's face is less soft than the background, this isn't a big issue. Sharpness is in a three-way tie for 4th place for factors that affect image quality.
Almost all TV's and projectors have at least a sharpness control. Setting this level to mid point or low is generally safer than putting it too high as an overly sharp image is generally much more distracting and annoying to watch than a slightly-under or normal sharpness setting.
