13megapixel

13 megapixels refers to a digital image resolution of approximately 13 million pixels. This is a common specification found in digital cameras, particularly in smartphones and point-and-shoot models. A megapixel is a unit of digital information equal to one million pixels. Pixels are the smallest individual units of a digital image.

When a camera sensor has a 13-megapixel resolution, it means the sensor is capable of capturing an image composed of roughly 13 million individual picture elements. The total number of pixels is usually calculated by multiplying the width and height of the image in pixels. For example, an image with a resolution of 4160 pixels by 3120 pixels would have approximately 12.9792 million pixels, often rounded up to 13 megapixels.

Higher megapixel counts generally allow for greater detail in an image and enable larger prints without significant loss of quality. However, megapixel count is not the sole determinant of image quality. Other factors such as sensor size, lens quality, image processing, and low-light performance play crucial roles. A 13-megapixel image can be cropped and enlarged to a certain extent before pixelation becomes noticeable, making it suitable for a variety of common uses like sharing on social media or printing in standard photo sizes.
