ABSTRACT:
A data imprinting device for a camera is provided which imprints symbolic data on a part of a photographing film. The data imprinting device comprises an object luminance photometric sensor for detecting luminance of an object in the vicinity of a symbolic data imprinting area, and a light emitting means including a light source for imprinting symbolic data in a photographing film. The brightness of the light source is controllable. In addition the device comprises a control means for controlling the brightness of the light source in the light emitting means according to the luminance of the object in the vicinity of the symbolic data imprinting area which is detected by the object luminance photometric sensor. In a second embodiment, the quantity of light emitted by the printing section is controlled according to the relationship between the detected luminance of the symbolic data imprinting area and the detected luminance of the areas other than the symbolic data imprinting area.
