Abstract
Official abstract text for this publication.
A heating cooking device includes a heater, a heating chamber, an imaging unit, a lighting unit, an image processor, and a lighting controller. The heating chamber accommodates an object to be heated. The imaging unit take images of the inside of the heating chamber. The lighting unit illuminates the inside of the heating chamber. The image processor analyzes an image to detect the brightness of the object to be heated in the image. The lighting controller controls the lighting unit in response to the brightness of the object to be heated. This aspect allows the heating cooking device to accurately determine a cooking state of the object to be heated on the basis of the image of the inside of the heating chamber taken to control the heater in response to the cooking state.
First claim
Opening claim text (preview).
1 . A heating cooking device comprising: a heater; a heating chamber configured to accommodate an object to be heated; an imaging unit configured to take an image of an inside of the heating chamber; a lighting unit configured to illuminate the inside of the heating chamber; an image processor configured to analyze the image and to detect brightness of the object to be heated in the image; and a lighting controller configured to control the lighting unit in response to the brightness of the object to be heated in the image. 2 . The heating cooking device of claim 1 , wherein the lighting unit has a plurality of lighting elements, and wherein the lighting controller is configured to turn on and off each of the plurality of lighting elements. 3 . The heating cooking device of claim 1 , wherein the lighting controller is configured to control the lighting unit to adjust halftone brightness. 4 . The heating cooking device of claim 1 , wherein the lighting controller is configured to control the lighting unit to increase illuminance at greater distances from the imaging unit.
