Provided are an electronic device capable of accurately measuring the effect of continuous beauty treatment based on the biological information acquired from a video, a method for controlling an electronic device, and a control program for an electronic device. The electronic device 1 includes: an imaging condition adjuster 111a that makes an imaging device capture a video of at least a part of a body to acquire pulse-wave information for adjustment indicating a pulse wave of the body based on the video, and adjusts an imaging condition based on the pulse-wave information for adjustment; and a video processing unit 111 that makes the imaging device capture a first video of at least a part of the body under the imaging condition adjusted by the imaging condition adjuster 111a to acquire video information on the body in the first video, and acquires first pulse-wave information on the body based on the video information on the body in the first video.

Techniques for updating zoom properties of corresponding salient objects are described that support parallel zooming for image comparison. In an implementation, a zoom input is received involving a salient object in a digital image in a user interface. An identification module identifies the salient object in the digital image and zoom properties for the salient object. A detection module identifies a corresponding salient object in at least one additional digital image and zoom properties for the corresponding salient object in the at least one additional digital image. An adjustment module then updates the zoom properties for the corresponding salient object in the at least one additional digital image based on the zoom properties for the salient object in the digital image.

An imaging apparatus includes: an imaging unit that generates image data; a feature information generation unit that generates feature information smaller in data amount than the image data, the feature information indicating features of a subject image included in an image corresponding to the image data; an imaging-side first and second communication units; a communication status determination unit that determines the status of communication between an external communication device and the imaging-side first communication unit; and an imaging-side communication control unit that transmits the feature information to the communication device via the imaging-side second communication unit when the status of communication between the communication device and the imaging-side first communication unit is not favorable.
