  • Patent number: 10848676
    Abstract: An object of the present disclosure is to continue optical image stabilization even in the case where a correcting lens is positioned near a mechanical end. An optical image stabilization module used to control a camera module adjusts the position of a correcting lens and the like used for optical image stabilization while executing the optical image stabilization during an exposure period. An image distortion accompanying the position adjustment of the correcting lens can be corrected by, for example, an electronic image stabilization module.
    Type: Grant

  • Patent number: 10750090
    Abstract: A semiconductor device for use in controlling a camera module performs position adjustment of a correction lens for use in optical camera shake correction, based on information representing a present position of the correction lens and position information of an output image of electronic camera shake correction with respect to a photographed image photographed by an imaging element. As a result, an operation margin of the correction lens is kept, while keeping a correction margin for the electronic camera shake correction.

  • Patent number: 6697906
    Abstract: A semiconductor device is connected to a CPU, a memory and I/O devices to serve as a data transfer bridge for efficient data transfer between the memory and the I/O devices. A CPU interface and a plurality of I/O interfaces included in a bridge chip are connected through an internal bus to a memory interface included in the bridge chip. Each I/O interface has a read/write buffer and a DMAC. An arbiter included in the bridge chip determines a bus master for which data transfer is permitted in response to requests for data transfer from each of the CPU interface and the DMAC to the memory. Each of the I/O interfaces has a control function to skip part of areas in the memory when transferring data between the memory and the I/O interface.
