Abstract

In order to, in a case where a composite image is to be generated that composites a background image and a person image, position the person image over the background easily, and allow the person andthe background to receive light in an identical manner so that natural composition can be carried out, a control device (6) for an electronic device (100a) includes: a person region extracting section(61) configured to extract a person image from a narrow-angle image captured by a narrow-angle camera (1); a background region extracting section (62) configured to extract a background image from awide-angle image captured by a wide-angle camera (2); and an image composite section (63) configured to make a composition of the background image and the person image, the narrow-angle camera (1) andthe wide-angle camera (2) being aimed in respective directions on an identical side relative to a housing of the electronic device.

Description

technical field [0001] The present invention relates to an electronic device, a control device and a control method for the electronic device, and a recording medium. Background technique [0002] Patent Document 1 discloses an image generation device in which a photographer can capture himself in a desired background by simultaneously photographing himself and a scene and superimposing the images. In this image generating device, the first imaging element and the first camera lens are arranged on one main surface (front) of the smartphone together with the display. On the other hand, the second imaging element and the second camera lens are disposed on the other main surface (rear surface). [0003] In addition, the control device of the image generation device includes a person region extraction unit, a person region tracking unit, a superimposed image generation unit, and a display control unit. The person area extracting section is configured to extract an image of a p...
