Regarding the differences between vga hardware 0.3M and 1.3M on the physical local display screen, as well as the differences in photo sizes, the tens of thousands of pixel camera refers to the length * width pixels of the photo. For example, 0.3M is already a very low pixel, with 540 * 540 pixels, resulting in a slightly blurry photo. The photos taken with 1.3M pixels are better, and if there are no issues with focusing, the photos taken will be relatively clear. The storage method of digital images is generally based on pixels, with each pixel being the smallest unit of area in the digital image. The larger the pixel, the larger the area of the image. To increase the area of an image, if there is no more light entering the photosensitive device, the only way is to increase the pixel area, which may affect the sharpness and clarity of the image. So, when the pixel area remains unchanged, the camera can obtain the maximum image pixel, which is the effective pixel. The larger the effective pixel, the clearer the image. Overall, photos taken with 300000 pixels have a hazy beauty, while photos taken with 1.3M pixels are clearer and can be selected as needed.
There is a significant difference in resolution, clarity, and image size between 0.3M and 1.3M.

Resolution: As pixels are the precision of an image, the image shape is composed of many small squares, which are pixels. Therefore, higher pixels mean higher quality images are output. The resolution of 0.3M is lower and may not be as clear as 1.3M. Generally speaking, the higher the pixel quality of a camera, the higher the quality, or the highest resolution of a camera represents its imaging quality. High pixel ensures clearer details and a larger dynamic range, providing more space for post-processing and improving transmission efficiency. Therefore, overall, 1.3M has better resolution than 0.3M.
Clarity: Higher pixels often lead to better image quality performance, and this difference in image quality is reflected in the different parsing abilities for various scenes during video recording. Therefore, in the same shooting environment, 1080P videos are generally clearer and more visible than 720P videos. In other words, high-definition brings a more delicate visual effect.
Image size: With the increase of camera or phone storage capacity, it is now easy to save very large photos without worrying about the storage card not being large enough or the device running slowly. Generally speaking, if set to the same jpeg format and scaled to a printable size, a 10M image will have a coverage of approximately one thousandth of an inch of photo area of over a thousand. That is to say, if the image is 56mm x 49.5mm and then enlarged to a maximum width of about four centimeters (excluding the head scale), using larger pixels will make it easier to observe every part of the image; However, the effective display size of landscape photos taken by smaller card machines, such as those with a size of around 3MP, is not enough. To see more details clearly, the screen needs to be pressed closer to view, which puts more pressure on the eyes and is not conducive to maintaining a certain distance and relaxing the mood while enjoying the beauty of the entire picture. In this situation, choosing products with larger pixels is clearly more advantageous.
In summary, this means that products with higher pixels can provide larger image volume and quality, allowing users to browse a large amount of information in a relatively small time span while enjoying a good visual experience. Although the specific actual performance may vary depending on the specific product, we can usually conclude that 1.3M has higher resolution and clarity compared to 0.3M, and also has significant advantages in uploading and downloading large files.
