  • Publication number: 20240083180
    Abstract: A printing apparatus includes at least a tank configured to hold a first printing material at a first position and a tank configured to hold a second printing material at a second position different from the first position. A light emitting control unit controls light emitting states of a plurality of light emitters. If an amount of the printing material in the first tank is less than a predetermined amount, and an amount of the printing material in the second tank is greater than a predetermined amount, the light emitting control unit transits a state of a first light emitter from a state indicating that the amount of the printing material is greater than the predetermined amount to a state indicating that the amount of the printing material is less than the predetermined amount, and maintains a state of a second light emitter.

A light emitting control unit controls light emitting states of a plurality of light emitters. If an amount of the printing material in the first tank is smaller than a predetermined amount, and an amount of the printing material in the second tank is larger than a predetermined amount, the light emitting control unit transits a state of a first light emitter from a state when the amount of the printing material is larger than the predetermined amount to a state when the amount of the printing material is smaller than the predetermined amount, and maintains a state of a second light emitter.

  • Patent number: 9648195
    Abstract: There is provided an image capturing apparatus. A first image capturing unit captures an image of a subject to generate image data. A second image capturing unit captures an image of a user who captures the image of the subject, for a predetermined period before and after the image of the subject is captured. An obtainment unit obtains first classification information by analyzing, in the image captured by the second image capturing unit, each of a state of the user before the image of the subject is captured and a state of the user after the image of the subject is captured. A recording unit records the first classification information in association with the image data.

  • Patent number: 9270902
    Abstract: Conventionally, on a subject in which range, refocus can be performed at the time of image capturing or at the time of editing an image is not specified clearly, and therefore, it is difficult for a user to capture an image or to edit an image in a manner the user intends. An image processing apparatus has an acquisition unit configured to acquire an image including a plurality of subject areas and distance information corresponding to the plurality of subject areas and a generation unit configured to generate a shifted image in which positions of the plurality of subject areas are shifted in the image based on the distance information.

  • Patent number: 8059182
    Abstract: An apparatus and method provides different animations or effects when screens of different groups of icons are switched. This technique prevents a user for mistakenly assuming that icons on different screens necessarily are related to each other, even if they occupy the same location on the screen.

  • Publication number: 20070030362
    Abstract: For two screen configurations with different icons are arranged in the same region, when screens are immediately switched from one to the other, the switching is not easy to be recognized, being mistaken that both icons have strong relationship with each other. After deleting a group of icons, the other group of icons is animated and arranged. Alternatively, a group of icons are deleted when the screen is switched, and after a window is animated in a region where the group of icons is displayed, the other group of icons is displayed.
