Image processing apparatus for cooker hood and cooker hood

Abstract

An image processing apparatus, in particular a camera apparatus and/or imaging apparatus for a cooker hood and a cooker hood. The camera apparatus includes a camera and/or the imaging apparatus includes an imaging device, an airflow generation apparatus, and an air channel, where an airflow generated by the airflow generation apparatus flows out of an outlet of the air channel. The outlet of the air channel is formed in a local area around the camera and/or imaging device. Disposing of the outlet of the air channel causes the airflow flowing out of the outlet of the air channel to form an air curtain in front of the camera and/or imaging device, thus preventing smoke from coming into contact with the camera and/or imaging device, protecting the camera and/or imaging device from pollution of smoke, and facilitating heat dissipation of the camera and/or imaging device.
