Besides, in heating chamber 13, food 12 and each of lightings 25a to 25d are close to each other. Therefore, a portion detected as white by image capturing unit 23 due to concentration of emitted light is generated.

Therefore, cooking device 11 changes the pulse width such that the luminance of each of lightings 25a to 25d is set to a predetermined set value according to a lighting pattern stored in lighting pattern storage unit 34. For example, cooking device 11 according to the present exemplary embodiment changes the pulse width so as to lower the luminance of each of lightings 25a to 25d by lighting level controller 41.
