  • Patent number: 8682031
    Abstract: The present invention enables the detecting and tracking of a specific subject using a simple structure and simplified operations without registering characteristic information of the subject. The invention comprises: a subject detection means that detects a subject image from an image; a subject-recognition-information storage means that stores a recognition ID of the subject image as well as a first position that is the position at which the subject image was last detected within the image; and a recognition ID assigning means that assigns the recognition ID to the subject image, wherein if the first position is within a predefined distance from the position at which the subject detection means detects the subject image, the recognition ID assigning means assigns the recognition ID corresponding to the first position to the subject image.

  • Patent number: 8049787
    Abstract: An image processing circuit capable of shooting a desired subject is provided in which increasing the size of the digital camera has been avoided. Sensor control unit 31 includes a moving image mode and a still image shooting mode. If a shutter button is operated when sensor control unit is driven in the moving image mode in which mechanical shutter 21 is open, image pickup control unit 37 stops the operation of sensor control unit. Then, after exposing image sensor 23 for a predetermined exposure time, image pickup control unit 37 closes mechanical shutter 21. Additionally, image pickup control unit 37 switches sensor control unit 31 to the still image shooting mode while mechanical shutter 21 is closed.

  • Patent number: 7443447
    Abstract: A camera device captures a plurality of images and superimposes them to output image data of a superimposed image. The plurality of images are captured by a plurality of cameras. A processor superimposes the plurality of images to produce the superimposed image, which is displayed on screen and is sent by moving-image mail.

  • Patent number: 7411618
    Abstract: A camera installed in a wireless terminal comprises a first electronic zooming means to operate by hardware and a second electronic zooming means to operate by software. The first electronic zooming means quickly select one of several pictures with predetermined scale factor. The second electronic zooming means zoom in or out a picture in small steps. An operator can quickly display a picture of desired scale factor by these two means. Further, in a foldable type terminal with a magnetic sensor, a picture with desired scale factor can be displayed by adjusting an angle between a first housing and a second housing.

  • Patent number: 5831833
    Abstract: Disclosed is a method of manufacturing bare chip mounting multi-layer printed circuit board in which arbitrary numbers of wiring circuit conductor layers and insulating layers are alternately stacked on one or both surfaces of a printed circuit board as a substrate, and a recessed portion with an upper opening capable of mounting and resin-encapsulating a bare chip part is formed on the surface of the printed circuit board, wherein at least the uppermost one of the insulating layers is made from a photosensitive resin, and the bare chip part mounting recessed portion is formed by photoetching the insulating layer made from the photosensitive resin. Since the bare chip part mounting recessed portion is formed by photoetching, the recessed portion can be easily and reliably formed. This results in a high product accuracy and allows a packaged part to be freely, additionally mounted even on the recessed portion.

  • Patent number: 5801438
    Abstract: In a multi-chip module, a laminate wiring board is formed with stepped recesses. Electrodes to be connected to the electrodes of a bare-chip semiconductor device are subjected to non-electrolytic gold plating. This realizes wire bonding which is as short in distance and as low in loop as possible. To seal each recess with insulating resin, use is made of screen printing using a mesh screen which has a great aperture ratio and a small thickness.
