Apple mobile phone camera related introduction:

1, the first generation of Apple had a 2-megapixel rear lens with a fixed focal length. They didn't have a flash, optical focal length and autofocus, so they didn't support shooting videos.

2. The camera lens of Apple 3 is made by OmniVision. It has a 3.2 megapixel lens, supports auto focus, auto white balance and auto macro, and can shoot 640 x 480 short films with 30 frames per second. Although it is different from the high-end CCD camcorder, it presents a rolling shutter effect, and short films can be cut on the iPhone and uploaded directly to the network.

3. Apple 4 has a 5 megapixel lens, which can shoot 720p short films and support high-resolution shooting. It also has a back-illuminated sensor, which can shoot in low light, and the LED flash can always be on when shooting. This is the first iPhone that can shoot with high dynamic range. There is also a front lens for video call, which can take VGA photos and SD short films. Stored records can be synchronized to the computer, sent by email attachment, or sent together with MMS.

4. Apple 5 is said to be able to capture the purple fog emitted by the light source, although Consumer Report pointed out that compared with previous generations of iPhone or other Android phones with fine lenses, it "is not so easy to capture the purple fog generated by bright light sources."

5. The brand-new 6s and 6sPlus have several upgrades, with the front and rear cameras upgraded to 5 million pixels/1200,000 pixels respectively.

6. The beta program of iOS 7 points out that Apple may assemble the slow-motion shooting mode in the lens of the next generation iPhone. On Apple 7, the front camera was upgraded to 7 million pixels.
