Description

Electric razor Technical Field The present disclosure relates to an electric razor for performing shaving of hairs of a body such as a beard. Background Conventionally, a shaving guidance system (shaving guidance system) has been proposed, which includes an imaging device for recording an image of a body part of a user, obtains a local hair growth direction based on the captured image, and instructs the user of a direction and a part in which the shaving device should be moved on the body based on the obtained hair occurrence direction (for example, refer to patent document 1). Prior art literature Patent literature Japanese patent application laid-open No. 2016-534806 Disclosure of Invention Problems to be solved by the invention However, in the conventional system, only the direction and the portion in which shaving is performed can be recognized, and the optimum shaving speed cannot be indicated. The present disclosure has been made in view of the above-described problems, and an object thereof is to provide an electric razor capable of notifying a user of an optimal shaving speed. Solution for solving the problem In order to achieve the above object, an electric razor according to one aspect of the present disclosure is an electric razor including a grip portion for a user to grip, and a head portion having a shaving portion for cutting body hair, the head portion being connected to one end of the grip portion, the electric razor including an imaging device for imaging a vicinity of skin where the shaving portion is in contact with, an image processing device for processing an image obtained from the imaging device, and a notification device for notifying a user of a processing result of the image processing device, wherein the image processing device includes a speed information generating portion for generating speed information indicating a shaving speed of the head portion with respect to the skin based on the image imaged by the imaging device, a shaving information generating portion for generating shaving information related to the shaving speed based on the speed information, and a result notification portion for controlling the notification device to notify the user of the shaving information. ADVANTAGEOUS EFFECTS OF INVENTION According to the electric razor of the present disclosure, the user can be notified of the optimal shaving speed, and the number of times of sliding to the same portion can be suppressed by the performance of the electric razor.
