Abstract
An imaging device comprises an image data acquisition circuit for forming a subject image while shifting focus position by a given amount and acquiring a plurality of image data, an image selection circuit for selecting images to be combined based on shift amount of focus position when image data was acquired by the image acquisition circuit, and image data resolution, and an image combination circuit for combining the plurality of image data that was selected by the image selection circuit, to generate image data having a large depth of field.

An imaging device, comprising:
- an image data acquisition circuit for repeatedly shifting a focus position by a given amount thereby defining a plurality of focus positions, forming a subject image at each of the plurality of focus positions, and acquiring a plurality of frames of image data from the formed subject images;
- a resolution conversion circuit that converts image data that has been acquired by the image data acquisition circuit to image data for storage, and to image data for display;
- an image selection circuit for selecting, from among the plurality of frames of image data, image data to be combined based on shift amount of focus position when image data was acquired by the image data acquisition circuit, and image data resolution;
- and
- an image combination circuit for combining the plurality of frames of image data that was selected by the image selection circuit, to generate image data having a large depth of field,
- wherein the image combining circuit, in a case where image data that has been subjected to resolution conversion by the resolution conversion circuit is subjected to image combination, selects frames of image data of a lower number of frames of images than a number of frames of images that are subjected to image combination in a case where resolution conversion is not carried out, using the image selection circuit, and carries out image combination.
An imaging device, comprising:
- an acquisition circuit repeatedly shifting a focus position by a given amount thereby defining a plurality of focus positions, forming a subject image at each of the plurality of focus positions, and acquiring a plurality of frames of image data from the formed subject images;
- a resolution conversion circuit for converting image data that has been acquired by the image data acquisition circuit to image data for storage, and to image data for display;
- an operation member for instructing actual shooting;
- an image combination circuit for, when the actual shooting has been instructed by the operation member, generating image data for storage by combining all of the plurality of frames of image data that have been acquired by the image data acquisition circuit, and further selecting some from among the plurality of frames of image data that were acquired by the image data acquisition circuit, and combining the selected image data to generate image data for confirmation of a large depth of field;
- and
- a display circuit for displaying a focus stacking image based on image data for confirmation that was combined by the image combination circuit,
- wherein the image combining circuit, in a case where image data that has been subjected to resolution conversion by the resolution conversion circuit is subjected to image combination, selects image data of a lower number of frames than a number of frames that are subjected to image combination in a case where resolution conversion is not carried out, using the image selection circuit, and carries out image combination.
A control method for an imaging device, having an image data acquisition circuit for forming a subject image and acquiring image data, a resolution conversion circuit for converting the resolution of the image data, and an image combining circuit for combining a plurality of frames of image data, the method comprising:
- repeatedly shifting a focus position by a given amount thereby defining a plurality of focus positions, forming a subject image at each of the plurality of focus positions, and acquiring a plurality of frames of image data from the formed subject images;
- selecting, from among the plurality of frames of image data, image data to be combined based on shift amount of focus position when the plurality of frames of image data were acquired, and resolution of the image data;
- and
- combining the plurality of selected image data to be combined, using the image combining circuit, to generate image data having a large depth of field,
- wherein, in a case where image data is subjected to image combination by the image combining circuit, image data of a lower number of frames than a number of frames that are subjected to image combination in a case where resolution conversion is not carried out by the resolution conversion circuit are selected, and image combination is carried out.
A non-transitory storage medium storing processor-executable instructions which, when executed by at least one processor, cause the at lease one processor to perform a control method for an imaging device, having an image data acquisition circuit for forming a subject image and acquiring image data, a resolution conversion circuit for converting the resolution of the image data, and an image combining circuit for combining a plurality of frames of image data, the method comprising:
- repeatedly shifting a focus position by a given amount thereby defining a plurality of focus positions, forming a subject image at leach of the plurality of focus positions, and acquiring a plurality of frames of image data from the formed subject images;
- selecting, from among the plurality of frames of image data, image data to be combined based on shift amount of focus position when the plurality of frames of image data were acquired, and resolution of the image data;
- and
- combining the plurality of selected image data to be combined, using the image combining circuit, to generate image data having a large depth of field,
- wherein in a case where image data is subjected to image combination by the image combining circuit, image data of a lower number of frames than a number of frames that are subjected to image combination in a case where resolution conversion is not carried out by the resolution conversion circuit are selected, and image combination is carried out.
