Problems solved by technology

[0005] However, when local high illuminance or shadows are generated due to the influence of lighting, the state of the food cannot be detected correctly and false recognition occurs, and the edge disappears from the captured image and the edge cannot be extracted, so the area of ​​the food cannot be detected.
[0006] In addition, when the food and its surrounding background have similar colors, it is difficult to separate the background from the food and detect the food correctly.
In addition, when the brightness of the food and the surrounding background are both high and whitish, it is more difficult to distinguish when the illuminance of the lighting is high

Embodiment approach 1

[0040] figure 1 It is a figure which shows the schematic structure of the main part of the heating cooker concerning Embodiment 1 of this invention. Figure 2A It is a figure which shows the schematic structure of another lighting pattern of the heating cooker which concerns on Embodiment 1 of this invention. Figure 2B It is a figure which shows the schematic structure of still another lighting pattern of the heating cooker concerning Embodiment 1 of this invention.

[0041] Such as figure 1 , Figure 2A and Figure 2B As shown, heating cooker 11 according to Embodiment 1 of the present invention has heating chamber 13 for accommodating food 12 as an object to be heated inside. The heating cooker 11 is configured to heat and cook an object to be heated by a heating source (not shown) such as a heater, a magnetron, or a steam generator.

[0042] The heating chamber 13 is composed of a ceiling 17 serving as walls, a left wall 18 , a back 19 , a right wall 20 , a bottom 21 ...

Embodiment approach 2

[0072] Next, heating cooker 11 according to Embodiment 2 of the present invention will be described. In the heating cooker 11 according to Embodiment 2 of the present invention, a large difference from the heating cooker 11 in Embodiment 1 is the structure in which the illumination degree is changed in the illumination degree control unit 33 .

[0073] In the following description of the heating cooker 11 according to the second embodiment of the present invention, the parts having the same configurations or functions as those of the heating cooker according to the first embodiment are denoted by the same reference numerals, and the detailed description thereof will be omitted here. description, and the description of Embodiment 1 is applied.

[0074] image 3 It is a figure which shows the schematic structure of the main part of the heating cooker concerning Embodiment 2 of this invention. Such as image 3 As shown, in the heating cooker 11 according to Embodiment 2 of the...

Abstract

Provided is a cooking device comprising: an image capturing unit (23) for capturing an image inside a heating chamber (13) for accommodating food (12); and an illumination degree control unit (33) forchanging the degree of illumination provided by lighting (25a-25d) for illuminating the inside of the heating chamber (13).

Description

technical field [0001] The present invention relates to a heating cooker for heat cooking food and the like. Background technique [0002] In a conventional heating cooker having a heating chamber, an imaging unit that captures images of the heating chamber may be provided in order to confirm the state of food as an object to be heated (for example, refer to Patent Document 1). In such a conventional heating cooker, image processing is performed based on an image captured by an imaging unit to recognize and judge the state of food being cooked, that is, the burnt degree of the food. [0003] In the configuration of such a conventional heating cooker having an imaging unit, it is unavoidable that the distance between the food in the heating chamber surrounded by the wall surface and the lighting becomes short. Therefore, the irradiated light from the light source is locally too strong, and the color of the food detected by the imaging unit is whiter than the actual color of ...
