  • Patent number: 9210328
    Abstract: A picture photographed by a camera portion is sent to a video capturing portion of a computer. The picture is displayed in an operation area of a monitor. A panorama picture of which pictures in part or all moving range of a pan tiler are combined is displayed in a panorama operation area. A pan tilter portion sends positional information of pan and tilt to the computer through a mode controller. With a mouse, the operation area and the panorama operation area are operated so as to select an object. The computer obtains data for driving the pan tilter. Thus, the selected object is displayed at the center of the operation area.

  • Patent number: 8068639
    Abstract: An image pickup apparatus includes: a face detection section configured to detect a face area from an image obtained by the image pickup apparatus; and a control section configured to detect at least any one of the amount of change in size of the face area detected by the face detection section and a movement speed of the face area, determine whether there is a possibility of occurrence of subject shake blur, which is blur occurring in a captured image due to the movement of a subject, on the basis of information on the detected amount of change in size of the face area or the detected movement speed of the face area, and output a warning when it is determined that there is a possibility of occurrence of subject shake blur.

  • Patent number: 7783186
    Abstract: An imaging apparatus includes a face detecting unit that detects a face area from an input image inputted in the imaging apparatus and a control unit that executes a focus operation according to adjustment of a focus lens. The control unit judges whether, during the focus operation, a new face has appeared in a position closer to the imaging apparatus than a position of a face closest to the imaging apparatus among faces detected before the start of the focus operation on the basis of the number and sizes of the faces detected and performs processing for re-executing or stopping the focus operation on the basis of a judgment result indicating that a new face has appeared in a position closer to the imaging apparatus.

  • Patent number: 7250974
    Abstract: An image pickup apparatus for electronically photographing a still image using a photo-voltaic transducer device. The focusing position of a focusing lens is detected from the contrast of the photographed image as AF supplementary light is illuminated on the object. The focusing lens then is moved to its focusing position and the contrast of the photographed image, in both the state where the AF supplementary light is illuminated and the contrast in the state where the AF supplementary light is not illuminated, is calculated. The contrast ratio between the contrast values of the two states is estimated and the focusing position is corrected based on this ratio.

  • Patent number: 7224396
    Abstract: The present invention concerns a digital still camera (1). This camera carries out a framing process by using an infrared pick-up image and a visible light photographing by using a flash or a low speed shutter in a still image pick-up process. Upon automatic focusing, the light of an auxiliary visible light source (23) for automatic focusing is emitted to apply the visible lights and carry out an automatic focusing process. In the digital still camera, the framing process can be carried out which allows the image of a subject which is to be picked up to be displayed on a finder even under an environment of low illuminance such as photographing a dark place and a user to recognize the contents of the photographed image. Further, after that, even when the visible light photographing is carried out through the irradiation of flash or the low speed shutter, an accurate focusing can be realized.

  • Publication number: 20060203122
    Abstract: An imaging apparatus can photograph without making a user feel a wasteful photographing impossible time and stress. The imaging apparatus has a light emission unit; an anticipated temperature calculator that calculates an anticipated temperature of the light emission unit based on a light emission state; and a controller for suppressing a charging current or a light emission energy of the light emission unit based on the anticipated temperature.
