Abstract
A camera which imprints alphanumeric messages on the film. The camera allows a user to view, in the order of most frequently used, the messages which can be imprinted. In order to reduce the cost of the camera, there is a dot matrix LCD display which can only display a limited number of characters which is less than the total number of characters of the largest message. After a user takes a picture, the dot matrix display scrolls through the message which has been imprinted on the film so that the user can confirm that the correct message has been imprinted. The speed at which the characters are scrolled or displayed is determined based on the total number of characters of the message. As an alternative to scrolling, the characters can be displayed one or two at a time. As an alternative, instead of displaying the alpha-numerical characters of the message, a graphical indication is given that some type of information has been imprinted on the film. The duration at which this confirmation of message imprinting is displayed or scrolled corresponds to the length of the message in order to give the user some indication of the message.
