Patent number: 9210328Abstract: 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.Type: GrantFiled: November 13, 2013Date of Patent: December 8, 2015Assignee: SONY CORPORATIONInventors: Masakazu Koyanagi, Tadafusa Tomitaka, Toshiyuki Iijima, Naoyasu Hosonuma, Ken Tamayama

Patent number: 9177386Abstract: There are provided an apparatus and a method for executing calculation of a global motion vector (GMV) with a high degree of reliability. Local motion vectors (LMV) corresponding to blocks and block weights as reliability indicators of the LMVs of the respective blocks are calculated, and the global motion vector (GMV) is calculated on the basis of the block weights. By calculating a degree of reliability of the local motion vector (LMV) corresponding to each block of a target block and near-field blocks adjacent to the target block and a degree of similarity between the local motion vectors (LMV) of the target block and each near-field block, the block weight is calculated through arithmetic processing to which the degree of reliability and the degree of similarity are applied. With the present configuration, it is possible to efficiently calculate the global motion vector (GMV) with a high degree of reliability.Type: GrantFiled: July 23, 2012Date of Patent: November 3, 2015Assignee: Sony CorporationInventors: Ken Tamayama, Masaki Handa, Tamaki Eyama
