A camera including a flashlight device for emitting a flashlight, a shutter, such that the camera has a flash synchro photographing mode in which the flashlight device emits the flashlight in synchronism with the shutter, a vibration detector for detecting a vibration quantity of the camera, a vibration correcting device for correcting an image blur on the basis of a vibration signal output from the vibration detector. The camera also includes a control device for controlling, while performing flash photographing by use of the flashlight device and driving the vibration correcting device, the shutter so that a maximum shutter time in the flash synchro photographing mode is shorter than or equal to a maximum shutter time in a non-emission of the flashlight. As a result, the flashlight device does not emit the flashlight.

A camera with a data imprinting device has a plurality of in-line LEDs producing light focused by an optical system upon a photographic film at a first and a second position, corresponding to a full size format and a panorama size format, respectively. The focused light imprints data images upon the film at the first position are larger than data images imprinted at the second position. The optical system has first and second prisms, with integrated lenses, for reflecting and focusing the light upon the film at the first and second positions, respectively. A shutter plate is selectively positioned over apertures through which the light is focused, thus blocking the light and allowing only a selected imprint to be made upon the film. A vertical pattern of the data image is created by a controller selectively illuminating the in-line LEDs while a horizontal pattern is produced by the controller illuminating the LEDs in coordination with the movement of the film past the apertures. The controller actuates a motor for advancing the film and has a sensor for detecting film travel. A first embodiment has the first prism positioned further from the film than the second prism, which is positioned further from the LEDs than the first prism, such that reflected light from the first prism has a path intersecting that of incident light of the second prism. A second embodiment has the prisms offset from each other in the plane of the film such that light paths do not intersect. The first embodiment has a narrower width than the second embodiment while the second embodiment has a shallower depth than the first embodiment.

There is disclosed an exposure control apparatus for a camera, enabling appropriate exposure control for varied photographing situations. The apparatus determines the optimum exposure value, referring to various conditions including the season and time of photographing, photographing location, sunrise/sunset times and so on.

A data imprinting device focusses light emitted from an array of LEDs onto the film, exposing the film as it is fed. A single chip microcomputer controls the LED array to imprint data. Some of the LEDs in the array are always energized together, while others are energized independently. The LEDs which are energized together require only a single control line, thus reducing the number of control lines, and consequently permitting reduction in the size of the camera. The group-wise serial activation of the dot matrix columns slightly staggers the imprinted data, but the imprinted characters are fully recognizable. In addition to reducing the number of control lines, the group-wise serial activation also reduces the peak load on the constant circuit, and thereby reduces the size of this circuit.

A camera having a photographic optical system contained in a lens barrel including a zoom cam tube and a collapsible mount cam tube. The zoom cam tube is movable in a focal length adjustment region between a Tele position and a Wide position, while the collapsible mount cam tube is movable in a collapsible mount movement region between the Wide position and a fully collapsed position. During focal length adjustment action, a gear which transmits a drive force of a motor is in engagement with a first rack on the zoom cam tube, and only the zoom cam tube rotates. Due to this rotation, a cam portion is rotated via other gears meshed with the first rack, and a pair of viewfinder lenses and a light generating unit, are made movable. During collapsible mount action, the gear is in engagement with a second rack, only the collapsible mount cam tube is rotated, and the drive force of the motor is not transmitted to the cam portion.

A camera having a vibration detection unit to detect the amount of vibration of a camera body and a vibration correction unit to compensate for the amount of vibration detected. The vibration detection unit requires a predetermined amount of time to determine the amount of vibration. If a user desires to take a photograph before the completion of the predetermined amount of time, the photograph will be taken without operation of the vibration correction unit. If the user desires to take a photograph after the completion of the predetermined amount of time, the vibration correction unit corrects for the vibration and, then, the photograph is taken. In addition, while the vibration correction unit is determining the amount of vibration, a display lamp blinks (a first state) and once the vibration detection unit has completed its performance, the display lamp continuously shines (a second state). Further, an indication may be given that the amount of vibration that has been determined is above a maximum value, thereby making the user aware that upper compensation of the vibration is not possible.
