Pixels per inch (PPI) (or pixels per centimeter (PPCM)) is a measurement of the pixel density (resolution) of devices in various contexts: typically computer displays, image scanners, and digital camera image sensors. It is defined as the horizontal or vertical density (for square pixels) as those are the same but the density on along the diagonal is lower.

The dimensions of these sensors are normally not standardised and result from the resolution and pixel sizes of the sensors. Everything is permitted and only limited by the budget. A line scan camera with 2048 pixels with 10 μm pixel sizes has a line length of 10.48 mm, in case of 14 μm pixel size the sensor is already 28.6 mm long.

DPI Calculator. The DPI calculator also referred to as the mouse DPI calculator, is used to calculate the dots in one inch of the display. To use overwatch DPI calculator, enter the horizontal and vertical pixels along with diagonal size in the input boxes given above. The diagonal size can be entered in millimetre, centimetre, and inches.

Image File Size: The file size of an image is expressed by the total number of pixels in the width and height of an image. For instance a file size might be written as 3,456 X 2,304. That means there are 3,456 total pixels in the combined rows of pixels in the image from left to right, and 2,304 total pixels in the combined columns of pixels from top to bottom.

It is also known as step size of DAC converter. Following DAC conversion formula/equation is used for this 8 bit DAC calculator. For example, consider 8 bit DAC which has 0 to 3 V as output voltage range. Now, the step size (or resolution) is equal to 3/2 8. This gives us 11.72 mV as resolution of DAC.

24-01-2012·Consider that a photo or image has 2 factors: canvas size and picture size normally both factor are equal. In HD the picture and canvas are 1920 x 1080 pixels at 72 dpi. What is DPI (dots per inch) more dpi more quality in but the quality can cause problem as example computer screen can use 72, 96 or 120 dpi. but to print a high quality on common printer you need at least 150 dpi or 300 or 600.

Resolution. This is Section 2.2 of the Imaging Resource Guide. Resolution is an imaging system’s ability to reproduce object detail. It can be influenced by factors such as the type of lighting used, the sensor pixel size, and the capabilities of the optics. The smaller the object detail, the higher the required resolution.

Pixel Dimensions and DPI There are three different ways to describe a digital image’s resolution that essentially mean the same thing: (1) total pixel dimensions, (2) DPI at a certain digital image size, and (3) DPI at a certain output size. The total pixel dimensions of an image will tell you how many total pixels (dots) the image is made up of.

DPI Calculator. DPI stands for Dots Per Inch. It is a measure of spatial printing or video dot density and is used to describe the image resolution number of dots per inch in a digital image print. Images printed with higher DPI have more detailed output. Use this online DPI calculator to calculate the image size in Dots Per Inch resolution.
