(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
In the context of image processing, binning is the procedure of combining clusters of adjacent pixels, throughout an image, into single pixels. For example, in 2x2 binning, an array of 4 pixels becomes a single larger pixel, [3] reducing the number of pixels to 1/4 and halving the image resolution in each dimension.
Although the most common medium format film, the 120 roll, is 6 cm (2.4 in) wide, and is most commonly shot square, the most common "medium-format" digital sensor sizes are approximately 48 mm × 36 mm (1.9 in × 1.4 in), which is roughly twice the size of a full-frame DSLR sensor format.
An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
The vertical resolution is usually a multiple of 8 or 16 pixels due to most video codecs processing pixels on such sized blocks. A widescreen FHD video can be 1920 × 800 for a 12∶5 ratio or 1920 × 1040 for roughly 1.85 × 1 , for instance.

The number of pixels n for a given maximum resolution (w horizontal pixels by h vertical pixels) is the product n = w × h. For example, an image 1600 × 1200 in size has 1,920,000 pixels, or 1.92 megapixels. The pixel count quoted by manufacturers can be misleading as it may not be the number of full-color pixels.
In the case of large format, 4 x 5 inch films can record approximately 298.7 million pixels, and 1,200 million pixels in the case of 8 x 10 inch film. However, as with a digital system, poor optical quality of lenses will decrease the resolving potential of a film emulsion. [7] [8] [9]
