Patent ID: 8350948

Claim:
An imaging device, comprising: an optical system formed so that an amount of blurring of a focal point becomes substantially constant at a focus position and at distances before and after the focal point, an imaging element capturing an object image passing through the optical system and generating an image signal, a converting means for correcting the blurring of the focal point of the image signal and generating a restored image signal, a signal processing means for performing predetermined image processing on one of the image signal and the restored image signal and generating a processed image, a switching means for selectively inputting the image signal or the restored image signal to the signal processing means, a storage means for storing the processed image of the signal processing means, a trigger signal generating means for generating a trigger signal instructing the image storage, an image monitoring means for displaying the processed image of the signal processing means, and a controlling means for inputting the image signal to the signal processing means through the switching means during display of a through image by the image monitoring means and, when receiving the trigger signal from the trigger signal generating means, inputting the restored image signal to the signal processing means.
