摘要: A pointing device includes a sensor obtaining image information, and an image producing unit producing a comparison image at predetermined time intervals by lowering a spatial resolution of an image based on the image information obtained by the sensor and increasing a density resolution of the image based on the image information. The device arithmetically obtains a correlation value indicating a correlation between a predetermined region in a first comparison image among the plurality of comparison images produced by the image producing unit and a predetermined region in a second comparison image produced after the first comparison image.

摘要: A self-synchronous FIFO memory device (100) has a structure in which n self-synchronous data transmission lines (111-11n) are arrayed in parallel. An input control section (101) selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a first transfer request signal, a first acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a preceding-stage section. Further, an output control section (102) selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a second transfer request signal, a second acknowledge (transfer instruction) signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a succeeding-stage section.
