2. As shown in the figure below, click the photos taken in the gallery to pop up the photo information bar, and click "Details".
3. As shown in the figure below, the height and width of the photo appear and are carefully recorded.
4. As shown in the figure below, calculated with a mobile phone calculator, it is 4608×3456= 15925248, which is160,000 pixels, that is, the maximum pixel reached by the camera when taking pictures with a mobile phone.
Extended data:
(1) The photo (or picture) stored in the computer already has a certain number of pixels, specifically, there are several pixels in the horizontal direction (represented by X) and several pixels in the horizontal direction (set to Y), so how many pixels are there in the whole picture (set to Z)? Z=X*Y
(2) The clarity of photos is directly related to the total number of pixels in the picture, so the resolution can be directly expressed by the number of pixels. Then the above formula is what you call the relationship between resolution and pixels, and (Z=X*Y) is their calculation method.
(3) A pixel refers to a small square of an image, which is called a pixel. These small squares have definite positions and assigned color values, and the color and position of these small squares determine the appearance of the image.
