The higher the PPI, the higher the image resolution and this also means the higher the image quality. Dot pitch is a measure used to determine the sharpness of an image. This is measured in millimeters (mm) and a smaller number means a sharper image. When you have closer spaced pixels, the image will look much sharper.
What factors affect picture quality?

- Image scaling. Speaking about factors that affect image quality, the primary thing to decide on is where these photos will be used.
- Sharpness.
- Digital noise.
- Distortion.
- Compressing images.
- Dynamic Range.
- Color Accuracy.
- Lens flare.
How can I improve picture quality?
To make a low quality picture high quality, you’ll need to correct its exposure for a start.
- Use auto enhancement. Auto enhance photos with light and color correction.
- Adjust exposure for better quality.
- Modify the chosen photo areas.
- Take care of white balance.
What determines good picture quality?
Main factors for pure image quality are:
Sensor quality (low noise, high dynamic range, and so on – all of which get better with a large sensor) Lens quality (sharpness, lack of chromatic abberation, quality of bokeh etc) Camera firmware, i e ability to use RAW format, or create JPEG files with good quality.
What are the 4 image quality factors?
The important components of the radiographic image quality include contrast, dynamic range, spatial resolution, noise, and artifacts. [3] We will discuss these components briefly.

There are four main factors that work together to create digital photo quality: The quality of the recording device (camera’s optics & sensor, scanner’s sensor). The size (in pixels) of the digital image. The digital format it is stored in (lossless vs lossy compression).

How does mAs affect image quality?
The first experiment showed that, when the film density is kept constant, the higher the kVp, the lower the resolution and image contrast percentage; also, the higher the mAs, the higher the resolution and image contrast percentage.
How does kVp affect image?
Radiation quality or kVp: it has a great effect on subject contrast. A lower kVp will make the x-ray beam less penetrating. This will result in a greater difference in attenuation between the different parts of the subject, leading to higher contrast. A higher kVp will make the x-ray beam more penetrating.
What is image quality?
Image quality can refer to the level of accuracy in which different imaging systems capture, process, store, compress, transmit and display the signals that form an image. Another definition refers to image quality as “the weighted combination of all of the visually significant attributes of an image”.
What causes low resolution in pictures?
A common cause for images to be of low quality is when it is enlarged without proper tools. Increasing the size of the image can often result in the photo losing its quality and resolution to drop significantly.

What does 7x optical zoom mean?
The Higher the Optical, the Better
In many cases, the optical is 3x with the additional 7x being digital. With camcorders, the optical zoom typically ranges from 10x to 64x, while the digital zoom can go from 100x to 1000x. See digital camera.
How far can 10x optical zoom See?
This means that if the camera you’re buying says 35 mm focal length with a 10x optical zoom, this means the minimum distance of the lens is 35 mm and the maximum zoomed-in distance would be 350 mm.
What does increasing kV do?
An increase in kVp extends and intensifies the x-ray emission spectrum, such that the maximal and average/effective energies are higher and the photon number/intensity is higher.
