Claims

[Claims for Utility Model Registration] (1) Focus adjustment information detection means for detecting focus adjustment information for focusing a photographic lens on a subject; By operating a focus lock means that performs focus lock based on focus adjustment information and a focus lock holding operation member,
a focus lock holding means that continues the focus lock even if the preliminary operation of the release operation member is canceled or even if the preliminary operation is performed again thereafter; and when the focus lock holding means is activated,
1. An operation control device for a camera, comprising: exposure control means for controlling an exposure value so that the shutter speed is faster than when the shutter is not in operation. (2) an electronic flash device, a focus adjustment information detection means for detecting focus adjustment information for focusing a photographic lens on a subject, and the focus adjustment information detected during preliminary operation of a release operation member prior to a release operation; By operating the focus lock means that performs focus lock based on the focus lock and the focus lock holding operation member,
a focus lock holding means that continues the focus lock even if the preliminary operation of the release operation member is canceled or even if the preliminary operation is performed again thereafter; a photometer that measures the light of a subject and outputs a photometered value; A first reference value of photometry related information, and a first reference value of photometry related information.
A second reference value corresponding to an object brighter than the reference value is set in advance, and when the focus lock holding means is not operating, the brightness of the object corresponding to the photometry related information regarding the output photometry value is set in advance. Outputting a light emission signal for causing the electronic flash device to emit light when the brightness of the subject corresponding to the first reference value is darker, and responding to the photometry related information when the focus lock holding means is operating. and a light emission signal output means for outputting a light emission signal for causing the electronic flash device to emit light when the brightness of the subject to be photographed is lower than the brightness of the subject corresponding to the second reference value. Camera operation control device. (3) A focus adjustment information detection means for detecting focus adjustment information for focusing a photographic lens on a subject; and a focus adjustment information detecting means for detecting focus adjustment information for focusing a photographic lens on a subject, and a focus lock based on the detected focus adjustment information in conjunction with a preliminary operation of a release operation member prior to a release operation. By operating the focus lock means and the focus lock holding operation member,
a focus lock holding means that continues the focus lock even if the preliminary operation of the release operation member is canceled or even if the preliminary operation is performed again thereafter; a photometer that measures the light of a subject and outputs a photometered value; A first reference value of photometry related information, and a first reference value of photometry related information.
A second reference value corresponding to an object brighter than the reference value is set in advance, and when the focus lock holding means is not operating, the brightness of the object corresponding to the photometry related information regarding the output photometry value is set in advance. A warning is generated when the brightness of the subject corresponding to the first reference value is lower than the brightness of the subject corresponding to the first reference value, and when the focus lock holding means is activated, the brightness of the subject corresponding to the photometry related information is lower than the second reference value. 1. A camera operation control device comprising: warning generating means for generating a warning when the brightness of a subject is darker than a reference value. (4) A focus adjustment information detection means for detecting focus adjustment information for focusing a photographic lens on a subject; and a focus adjustment information detecting means for detecting focus adjustment information for focusing a photographic lens on a subject, and a focus lock based on the detected focus adjustment information in conjunction with a preliminary operation of a release operation member prior to a release operation. By operating the focus lock means and the focus lock holding operation member,
a focus lock holding means that continues the focus lock even if the preliminary operation of the release operation member is canceled or even if the preliminary operation is performed again thereafter; a photometer that measures the light of a subject and outputs a photometered value; and a prohibition means for prohibiting photographing when the photometry related information regarding the output photometry value indicates that the subject is darker than predetermined reference photometry related information when the focus lock holding means is operating. A camera operation control device characterized by:
