In an embodiment, an electronic device includes circuitry configured to automatically execute exposures at a photographing range including at least a first region and a second region, with different focuses by a camera, and acquire first images generated by the exposures, and display a second image on a display based on the first images. A number of exposures at the photographing range of a first photographing and a second photographing are different. The first photographing is a case when a difference between a distance from the camera to the first subject and a distance from the camera to the second subject is greater than or equal to a first value. The second photographing is a case when the difference is smaller than the first value.

Electronic device, method and storage medium for generating an image

According to one embodiment, a search skip region setting function generation method includes estimating. The estimating includes estimating a relative position between a object and a template based on a distribution of surrounding search point similarities, and generates a function required to set a search skip region which allows to skip the object search on each model reduced-scale image based on the estimated relative position.

Search skip region setting function generation method, search skip region setting method, object search method, search skip region setting function generation apparatus, search skip region setting apparatus, and object search apparatus

According to one embodiment, a search skip region setting function generation method includes associating, detecting, and generating. The associating associates a template used to search a model image for an object with a designated search point on the model image, and detects a designated search point similarity between the designated search point and the template. When the designated search point similarity exceeds an object detection determination threshold, the detecting detects surrounding search point similarities between a plurality of surrounding search points around the designated search point on the model image and the template. The generating generates a function required to set a search skip region of the object based on relative positions between the object and the template, which are estimated based on a distribution of the surrounding search point similarities.
