iOS has always tried to simulate zero shutter lag: the camera continuously captures full-resolution images into a ring buffer, and the app goes back in the frame buffer to find the image that corresponds to when you pressed the shutter.
- _pmf_ 10y agoThis sounds like a good way to drain the battery, and it will only work when no flash is required.
- tarancato 10y agoStill better than nothing.
- pjc50 10y agoPresumably it's quite cheap if you have enough RAM and hardware JPEG acceleration; the camera has to capture a string of images to display on the screen anyway.
- JustSomeNobody 10y agoNothing comes without a cost.
- dx034 10y agoZero shutter lag is what I love about the iPhone. Compared to my previous Xperia Z5, the pictures on the iPhone are not better (rather worse at bad light conditions), but I never have to wait to take one. The time it can take the Z5 to focus and finally take a picture is annoying.
