  • Patent number: 11933234
    Abstract: An engine is provided with a turbo charger including a wastegate valve. A first setpoint of opening of the wastegate valve is set in accordance with a target boost pressure. While a difference between the target boost pressure and a real boost pressure is large, the opening is controlled to a second setpoint, wherein the second setpoint is smaller than the first setpoint. While the opening is controlled to the second setpoint, it is determined whether a condition for limitation is satisfied in which an intake air quantity is above an intake air quantity criterion and an engine rotation speed is above an engine rotation speed criterion. When the condition is satisfied, the opening is controlled in a direction to increase from the second setpoint. The engine rotation speed criterion decreases as the intake air quantity increases. The intake air quantity criterion decreases as the engine rotation speed increases.

  • Patent number: 9936158
    Abstract: The present invention enables automatic generation of an image in which only an impressive color is kept, without requiring a complicated operation. A digital camera 100 divides an image obtained by an imaging unit 20 into regions based on color information and luminance information, and determines a characteristic object in accordance with a characteristic degree of each region into which the image is divided. Further, a region for keeping a color is set in which the color of the characteristic object is to be kept. A color conversion process is then performed so as to keep the color of the characteristic object in the region for keeping a color, and to change colors of the other regions to an achromatic color.

  • Patent number: 9083159
    Abstract: An object of the invention is to provide a cable support member having high durability and excellent manufacturing performance. A cable support member of the invention includes: a plurality of holding members; and an elastic member. Each holding member has an elastic member insertion passage through which the elastic member is inserted, and has joint surfaces enabling a rotation of the holding member with coming into contact with the adjacent holding members at both sides in the longitudinal direction. The elastic member is inserted through the elastic member insertion passages in the holding members so as to align and maintain the holding members, and exerts a compression force on the holding members. With such a configuration, a neutral state where the cable support member is substantially in a linear fashion and a curved state where the cable support member is bending-deformed are obtainable.

  • Patent number: 8982244
    Abstract: A low-frequency region of an output target image is specified. Luminance correction is performed with the target amount decided in advance for a pixel, among pixels included in the target image, which is included in the low-frequency region and has a luminance value equal to or smaller than a predetermined value, and the target image after the correction is output. Then, an effective correction amount is obtained based on the luminance distribution of the target image before the correction and the luminance distribution of the target image after the correction, which has been corrected with the target amount decided in advance. A luminance correction target amount for the next correction target image is decided based on the luminance distribution of the target image and the ratio of the effective correction amount to the target amount decided in advance.

  • Patent number: 8929727
    Abstract: An image pickup apparatus that is capable of reducing variation in the color temperature of a subject in a taken image and capable of shooting a more suitable image. The image pickup apparatus can shoot with emitting a light emitting unit. A color temperature acquisition unit acquires information about a color temperature of a light illuminating a subject. An emission control unit controls emission of the light emitting unit. The emission control unit determines emission light amount of the light emitting unit based on a color temperature difference between a color temperature of an illumination light of the light emitting unit and a color temperature based on the information acquired by the color temperature information acquisition unit.

  • Patent number: RE45629
    Abstract: Subjects are detected in a captured image and a main subject is selected from the detected subjects. Focusing areas are set up that correspond to the detected subjects and focus detection is performed in the focusing areas that have been set up. When providing in-focus indication representing focus detection results, focus detection results associated with the particular focusing area among the focusing areas that corresponds to the main subject are displayed in a manner different from focus detection results associated with those focusing areas within the depth of field that correspond to subjects other than the main subject.
