![]() ![]() If we wish to make is smaller, and the condition is that the quality remains the same or in other way the image does not get distorted, here how it happens. This is a sample image, which has 100 rows and 100 columns. It does not let the image to get distorted when aspect ratio is increased. The common aspect ratios are:ġ.33:1, 1.37:1, 1.43:1, 1.50:1, 1.56:1, 1.66:1, 1.75:1, 1.78:1, 1.85:1, 2.00:1, e.t.c AdvantageĪspect ratio maintains a balance between the appearance of an image on the screen, means it maintains a ratio between horizontal and vertical pixels. This ratio differs in different images, and in different screens. It is commonly explained as two numbers separated by a colon (8:9). Aspect ratioĪnother important concept with the pixel resolution is aspect ratio.Īspect ratio is the ratio between width of an image and the height of an image. ![]() Its pixel resolution = 2500 * 3192 = 7982350 bytes.ĭividing it by 1 million = 7.9 = 8 mega pixel (approximately). Lets say we have an image of dimension: 2500 X 3192. Size = pixel resolution X bpp ( bits per pixel ) Calculating the mega pixels of the camera The size of an image can be defined by its pixel resolution. We can calculate mega pixels of a camera using pixel resolution.Ĭolumn pixels (width ) X row pixels ( height ) / 1 Million. We can define pixel resolution of an image as 4500 X 5500. We can say that the higher is the pixel resolution, the higher is the quality of the image. The first number the width of the picture, or the pixels across columns, and the second number is height of the picture, or the pixels across its width. If we define resolution as the total number of pixels, then pixel resolution can be defined with set of two numbers. If an image has M rows and N columns, then its resolution can be defined as M X N. In pixel resolution, the term resolution refers to the total number of count of pixels in an digital image. You have probably seen that in your own computer settings, you have monitor resolution of 800 x 600, 640 x 480 e.t.c Out of which we are going to discuss pixel resolution. Such as pixel resolution, spatial resolution, temporal resolution, spectral resolution. The resolution can be defined in many ways. Now since we have defined a pixel, we are going to define what is resolution. We also defined that a pixel can store a value proportional to the light intensity at that particular location. We have already defined a pixel in our tutorial of concept of pixel, in which we define a pixel as the smallest element of an image. Before we define pixel resolution, it is necessary to define a pixel.
