[0128] The first embodiment describes a structure in which the timing when the subject to be photographed satisfies a preset condition is estimated and image data corresponding to the predicted timing is stored and controlled. However, the estimation target is not limited to the imaging timing. The second embodiment will describe a structure in which shooting conditions such as exposure and focus at a timing suitable for shooting are estimated, and an image is captured under the shooting conditions.

[0129] figure 2 It is a block diagram showing the structure of the main part of the imaging apparatus according to the second embodiment. The structure according to the second embodiment includes in addition to the structure of the first embodiment: an imaging condition control unit 10 for controlling shooting conditions such as exposure and focus; and a distance measuring unit 29 for measuring the subject and imaging The distance between the devices. The remaining main structural ...

Abstract

An imaging device and an imaging method, in the imaging device, a video input unit (2) captures an image of an object and sequentially acquires image data related to the image capturing; a model data memory (6) stores the data obtained from the model image The model data related to the first feature quantity calculated by the feature points of the subject; the main subject detection unit (3) calculates the second feature quantity from the feature points of the subject in the obtained image data; A state change estimating unit (4) estimates a timing at which the subject satisfies a predetermined condition based on the second feature quantity and the model data; an image input processing control unit (7) stores image data corresponding to the estimated timing Stored in the image recording unit (5). This structure allows the imaging device to acquire images in a more suitable state without requiring a large-capacity memory.

Description

Technical field [0001] The present invention relates to an imaging device, and more particularly, to an imaging device that automatically captures images according to imaging conditions. The present invention also relates to a camera technology for simultaneously shooting motion and still images. Background technique [0002] Conventionally, there has been known a technology related to an imaging device that automatically captures images according to imaging conditions. [0003] Japanese Patent Application Laid-Open No. 2000-259833 discloses a technique that determines the facial state of a person from successive images and selects an image showing the best facial state. [0004] Japanese Patent No. 3240339 discloses a technique that uses the pixel correspondence between different images of the recorded moving image data to perform interpolation processing when the image at the time desired by the user does not exist, thereby generating the user The image at the desired moment. ...
