Abstract

Abstract A photographic information setting device for a camera of the present invention comprises mode switches for switching a first type exposure mode to a second type exposure mode, and vice versa. The changing rate for altering values relative to exposure in the first type mode is different from that in the second type mode. The changing rate of the second type mode is smaller than that of the first type mode. Values to be set in the second type mode contain values to be set in the first type mode. This device also comprises a microcomputer which shifts a value set under the second type mode to a value set under the first type mode when the second type mode is switched to the first type mode.

Claim 6
Dependent Claim 123 words
A photographic information setting device for a camera comprising: shutter speed setting means which has at least one operating member for shifting a shutter speed value step by step at predetermined regular intervals, thereby being able to select a shutter speed value from among a plurality of values set at the predetermined regular intervals; operable means manually operated; interval altering means for altering intervals of shutter speed values to be shifted by the operating member from predetermined regular intervals of one type to ones of another type, and vice versa, in response to the manual operation of said operable means; and shutter speed controlling means for controlling a shutter speed based on the shutter speed value set by the shutter speed setting means.
Claim 7
Dependent Claim 123 words
A photographic information setting device for a camera comprising: shutter speed setting means which has at least one operating member for shifting a shutter speed value step by step at predetermined regular intervals, thereby being able to select a shutter speed value from among a plurality of values set at the predetermined regular intervals; operable means manually operated; interval altering means for altering intervals of shutter speed values to be shifted by the operating member from predetermined regular intervals of one type to ones of another type, and vice versa, in response to the manual operation of said operable means; and shutter speed controlling means for controlling a shutter speed based on the shutter speed value set by the shutter speed setting means.
Claim 8
Dependent Claim 175 words
A photographic information setting device for a camera comprising: exposure information setting means for selecting a value from among values relative to exposure which are set in advance at predetermined regular intervals so as to set exposure information for a camera; interval altering means for altering predetermined regular intervals between a first type and a second type having a smaller step than the first type; exposure controlling means for effecting an exposure control based on the exposure information set by the exposure information setting means; and display means having a first display portion for displaying set values relative to exposure and being adapted to numerically display a value included in the values set in advance at the predetermined interval of the first type and a second display portion for displaying set values relative to exposure and being adapted to indicate a value included in the values set in advance at the predetermined interval of the second type by displaying a fraction shifted from the value of the first type displayed at the first display portion.
Claim 9
