Nowadays, a digital camera or a mobile phone is used to capture images. Most of the cameras and the mobile phones use an autofocus technology. However, sometimes happens the area being captured by the camera or mobile phone is out of focus, especially when different subjects are at different distances in the scene.
To overcome the shortcoming described above, a method of capturing images with multiple focuses through infrared automatic focus or contrast automatic focus is used. A plurality of images is captured from the far object distance to the near object distance to form an image array. Each area of the view is checked and the clear image from the image array is picked according to the object distance of the selected area. However, in many cases, when taking a plurality of images from the far object distance to the near object distance, there will be many unused images, resulting in wasted time, storage space, and increased cost of the image capturing device.
