Claims

[Scope of Claim for Utility Model Registration] (1) A focus adjustment information detection means for detecting focus adjustment information for focusing a photographic lens on a subject; a photometry means for measuring light on a subject and outputting a photometry value; The release preliminary signal is generated by the operation of
a release operation member that generates a release signal by a second operation subsequent to the first operation; and a release operation member that operates the focus adjustment information detection means upon generation of the release preliminary signal, and stores and retains the focus adjustment information at that point in time. Focus locking means; AE locking means for storing and retaining information corresponding to a photometric value output from the photometric means in response to generation of the release preliminary signal, and when the release signal is generated, the stored focus is activated. A camera operation control device configured to perform focusing by driving the photographic lens based on adjustment information, comprising: a focus lock holding operation member that generates a focus lock holding signal in response to manual operation; and a focus lock holding operation member that is activated when the focus lock holding signal is generated. and a focus lock holding means that continues to store and hold the focus adjustment information even if the first operation of the release operation member is canceled and even if the first operation is performed again after that; and the focus lock holding means. in response to the generation of the release signal when inactive;
Exposure is controlled based on information corresponding to the photometric value stored and held by the AE locking means, and when the focus lock holding means is activated, the photometric means is activated in response to generation of the release signal. 1. An operation control device for a camera, comprising: exposure control means for controlling exposure based on a photometric value output at that time. (2) a focus adjustment information detection means for detecting focus adjustment information for focusing the photographing lens on the subject; a light metering means for measuring the light of the subject and outputting a light metering value; and generating a release preliminary signal by the first operation. death,
a release operation member that generates a release signal by a second operation subsequent to the first operation; and a release operation member that generates a release signal by a second operation following the first operation; a focus lock means that performs a focus lock to focus the photographic lens on and hold the photographic lens in that state; and an AE lock means that stores and holds information corresponding to the photometric value output from the photometric means upon generation of the release preliminary signal. A camera operation control device comprising: a focus lock holding operation member that generates a focus lock holding signal in response to manual operation; and a focus lock holding operation member that is activated when the focus lock holding signal is generated to release the first operation of the release operation member. and a focus lock holding means for continuing the focus lock even if the first operation is performed again thereafter; and in response to generation of the release signal when the focus lock holding means is not operating;
Exposure is controlled based on information corresponding to the photometric value stored and held by the AE locking means, and when the focus lock holding means is operating, the photometric means is activated in response to generation of the release signal. 1. An operation control device for a camera, comprising an exposure control means for controlling exposure based on a photometric value outputted at that time.
