摘要:
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.

A focus state detection device comprising: a first optical conversional system for forming an optical flux in one of two symmetric regions with respect to an optical axis of an optical flux from a subject to be photographed; a second optical conversional system for forming an optical flux in the other of the two symmetric regions; and a third optical conversional system for forming an optical flux in a region including the optical axis. The device further comprises a first and a second photoelectric converters for generating electric signals in response to optical intensity distribution data of the fluxes formed by the first and second systems, respedtively; a third photoelectric converter for generating an electric signal in response to optical intensity distribution data of the flux formed by the third system; and a calculation unit for detecting a focus state of the subject on the basis of correlation between three electric signals output from the first, second and third converter means.

In a focusing state detector, a light beam transmitted through a photographing lens is divided into three light beams in three regions through a condenser lens and three converting optical systems. The three light beams are focused and formed as an image on three photoelectric converting portions and are photoelectrically converted to three kinds of electric signals. A correction calculator receives data of an integral time ratio provided by a charge coupled device at a plurality of time points from a correction coefficient calculator. The correction calculator corrects image data obtained by the three photoelectric converting portions by using a correction coefficient according to the integral time ratio. A phase difference calculator receives the corrected image data of the correction calculator and provides phase difference data. The focusing state of a lens system is accurately detected even when a photographed object is moved in a direction perpendicular to an optical axis of the lens system in a plurality of detections of the detecting state and a brightness distribution of the photographed object is changed.
