  • Patent number: 8823831
    Abstract: In an image data processing apparatus, a conversion unit generates first image data of a first image format and second image data of a second image format and supplies the first and second image data on a time division basis with respect to each image taken by using an image sensor. An operating unit acquires the first and second image data produced on a time division basis from the conversion unit, performs a process for displaying the taken image on a display device by using the first image data, and performs a process for storing the taken image in a storage device by using the second image data.

  • Patent number: 8717445
    Abstract: An image pickup apparatus includes an imaging element for acquiring an image of a target object; a detector for detecting movement of the image pickup apparatus; and a controller for controlling focus of the imaging element on the target object while the movement of the image pickup apparatus detected by the detector is not more than a threshold degree.

  • Patent number: 8687105
    Abstract: An image capturing apparatus includes an image capturing unit having a function for adjusting a focal length, a stillness determination unit which determines whether or not a motion of the image capturing apparatus is within a predetermined range, a focal length adjustment processing unit which performs first focal length adjustment processing which adjusts the focal length in a direction for close-up photography when the motion of the image capturing apparatus is within the predetermined range, and a code recognition processing unit which recognizes a code from an image captured by the image capturing unit while the first focal length adjustment processing is being performed.

  • Patent number: 8026932
    Abstract: An image pickup apparatus includes: a first base image selection unit selecting a piece of image data as a first base image used in superposition; a shift amount calculation unit calculating an amount of shift between the first base image and another different piece of image data; an image superposition unit detecting a superposing area as an area in which the different piece of image data can be superposed on the first base image after a shift correction is made on a basis of the calculated amount of shift, and performing superposition for the superposing area; a second base image selection unit selecting a piece of image data as a second base image used in a non-superposing area; and an image combination unit combining a superposition result with the non-superposing area in the second base image, and outputting image data as a combination result.

  • Patent number: 7680402
    Abstract: An image shooting device with a camera shake correction function is provided. The image shooting device is capable of avoiding the deterioration of image quality due to performing camera shake correction. An image shooting control unit of the image shooting device can be configured to select to take in either one piece of image data for ordinary image shooting or a plurality of pieces of image data for camera shake correction, on the basis of the determination result of a determination unit. It also can be configured to take in both one piece of image data for ordinary image shooting and a plurality of pieces of image data for camera shake correction.
