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: A first imaging device that images the vicinity of the skin on which the shaving portion is in contact; an image processing device for processing the image obtained from the first image pickup device, and A notification device that notifies a user of a processing result of the image processing device, Wherein the image processing device comprises: a character information generation unit that generates character information indicating at least one of a skin color, a body hair, and a skin texture, based on the acquired image; A shaving information generating unit that calculates a motion vector of at least one of a skin-focused texture and a body hair from images captured at predetermined intervals, generates excessive shaving information when a speed obtained from the motion vector is equal to or higher than a speed threshold, or calculates a body hair shake width or a skin texture shake width from one image captured at a predetermined shutter speed, generates excessive shaving information when a speed obtained from the shutter speed and the shake width is equal to or higher than the speed threshold, and A result notifying unit that controls the notifying means to notify the user of the shaving information, The head comprises a head base body and a head frame body, the first outer blade and the second outer blade of the shaving part are mounted on the head frame body, the shaving part can be assembled and disassembled relative to the head base body, and the first camera device is fixed on the head base body and does not become an obstacle when the head frame body is assembled and disassembled.

Description

Electric razor Technical Field The present disclosure relates to an electric razor for performing shaving of hairs of a body of 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 an optimum shaving state for reducing damage to skin or the like cannot be instructed. 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 instruction for suppressing damage to skin. Solution for solving the problem In order to achieve the above object, an electric razor according to one aspect of the present disclosure includes 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 a first 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 first 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 property information generating portion for generating property information indicating a property of at least one selected from a group consisting of body hair and skin based on the acquired image, a shaving information generating portion for generating shaving information related to shaving based on the property information, and a result notification portion for controlling the notification device to notify the user of the shaving information.
