What is a front camera?

The front-facing camera was developed by mobile phone manufacturers to meet people's needs for video calls. As the name suggests, the front-facing camera is placed in front of the mobile phone, so that when you are making a video call with others, you can view your Transfer video to others. The pixels are around 300,000.

The main parameters measured by the camera. Resolution (pixels) Resolution is one of the parameters we are most familiar with. The resolution is mainly determined by the image sensor. The higher the resolution, the more detailed the image and the better the effect, but the image takes up more storage space. Generally speaking, camera pixels are the maximum pixels in photo mode. The pixels in photography (video) are usually smaller. For example, the N97 camera has 5 million pixels, but the maximum resolution in photography mode is only 640 x480.

The number of pixels in a digital camera includes Effective Pixels and Maximum Pixels. Different from the maximum pixels, the number of effective pixels refers to the pixel value that actually participates in photosensitive imaging, and the value of the highest pixel is the real pixel of the photosensitive device. This data usually includes the non-imaging part of the photosensitive device, and the effective pixels are when the lens zooms. The value converted under magnification.

The English name of the effective number of pixels is Effective Pixels. Different from the maximum pixels, the effective number of pixels refers to the pixel value that actually participates in photosensitive imaging. The highest pixel value is the actual pixel of the photosensitive device.

Digital images are generally stored in pixels, and each pixel is the smallest unit in a digital image. The larger the pixels, the larger the image area. To increase the area size of a picture, if no more light enters the photosensitive device, the only way is to increase the area of ??the pixels, which may affect the sharpness and clarity of the picture. Therefore, when the pixel area remains unchanged, the largest picture pixel that a digital camera can obtain is the effective pixel.
