Abstract:
The present invention relates to a color marker recognizing device using a color marker. The color marker recognizing device includes a coloring unit and a content unit. The coloring unit acquires a sub marker image from color marker images according to contextual information on a user. The content unit outputs a first content demand signal that requests to display a first content corresponding to the sub marker image acquired by the coloring unit. Since the color marker recognizing device uses the color marker, it is possible to provide personalized content services.
Abstract:
A cooking apparatus equipped with heaters and a method of controlling the same. An aspect of the present invention is to increase convenience of a user by identifying a kind of an accessory, such as a wire rack, a crumb tray or the like, present in a cooking cavity based on a variation in an inner temperature of a cooking cavity at an initial operating stage of a cooking mode using the heaters and automatically performing the ON/OFF control mode of the heaters suitable for a corresponding accessory. A cooking apparatus is provided including two or more heaters installed in a first position of a cooking cavity heating food, the crumb tray is inserted in a second position of the cooking cavity and is used to contain the food in cooking modes using the heaters, and a temperature detection unit is installed between the first and second positions to detect an inside temperature of the cooking cavity. When a temperature variation rate of the cooking cavity detected by the temperature detection unit is greater than a preset value, the crumb tray is determined to be used as a cooking accessory, so an ON/OFF state of the heaters is controlled to be suitable for the cooking mode using the crumb tray.

Abstract:
A microwave oven performs a cooking operation in one of several cooking modes having a first cooking time period and a second cooking time period. The first cooking time period is determined in accordance with an output value of a sensor which senses a state of air in a cooking cavity of the microwave oven. The second cooking time period is determined in accordance with the first cooking time period such that the first and second cooking time periods are expressed by a functional relation. The cooking modes include a standard mode with a standard second cooking time period, a high mode with a longer cooking time than the standard second cooking time period, and a low mode with a shorter cooking time than the standard second cooking time period. The high mode is preset such that a variation in its second cooking time period is increased in proportion to the first cooking time period, while the low mode is preset such that a variation in its second cooking time period is increased in inverse proportion to the first cooking time period. The microwave oven allows a user to set a cooking time period such that the cooking time period is controllably lengthened or shortened in proportion to the quantity of food contained in the microwave oven.
Abstract:
A data obtaining method for a microwave oven for processing a cooking status of food detected by a sensor into data, including the steps of: detecting data from food for a predetermined time period; calculating a summation of the detected data; and subtracting data about characteristics of the microwave oven which are prestored in the microwave oven from the detected data.
Abstract:
A food amount detector for automatically detecting the amount of a food placed in a cooking chamber of a microwave oven, a microwave oven employing the food amount detector, and control method thereof. Output voltage of a microwave generator is detected while the microwave oven is driven, and the amount of the food placed in the cooking chamber of the microwave oven is determined based on the output voltage such detected. In accordance with the amount of the food such determined, the food is cooked under the appropriate driving conditions of the microwave oven. Accordingly, the user does not need to determine the amount of the food by himself, or set the driving conditions of the microwave oven such as cooking time, level of microwave energy, etc. As a result, the user finds it convenient when using this microwave oven, and the food is cooked under the exact driving conditions set by the microwave oven. Further, since the price of the parts are inexpensive, the manufacturing cost is reduced, and manufacturing process is simplified, so that productivity is improved.
