Abstract:
1. An image pick-up method using a charge-transfer type solid-state image pick-up device wherein the charge-transfer type solid-state image pick-up device comprises: high sensitivity photoelectric conversion elements for executing photoelectric conversion with relatively high sensitivity; low sensitivity photoelectric conversion elements for executing photoelectric conversion with relatively low sensitivity; and vertical transfer channels for transferring signal charges from said high sensitivity photoelectric conversion elements and said low sensitivity photoelectric conversion elements, the method comprising: a charge transfer step of individually reading/transferring first signal charges from said high sensitivity photoelectric conversion elements and second signal charges from said low sensitivity photoelectric conversion elements onto said vertical transfer channels, without executing a high speed charge transfer operation for the vertical transfer channels after exposure of said solid-state image pick-up device; a smear component acquiring step of, using a first signal based on the first signal charges transferred and a second signal based on the second signal charges transferred, acquiring a smear component contained in one of the first signal and the second signal; and a smear component correcting step of correcting the one of the first signal and the second signal using said smear component thus acquired.
