  • Publication number: 20170097682
    Abstract: A tactile sensation data processing apparatus includes a data receiving part that receives first data relating to a target tangible object from a first portable electronic terminal; and a data transmitting part that transmits, to a second portable electronic terminal, tactile sensation data that represents tactile sensations of the target tangible object. The tactile sensation data associates an image of the target tangible object with positions in the image and amplitudes corresponding to the tactile sensations at the respective positions. The tactile sensation data is used when adjusting an amplitude of a driving signal that drives a vibrating element that generates a natural vibration in an ultrasound frequency band in a manipulation input surface where a manipulation input is performed on a touch panel, based on an amplitude associated with a position in the image corresponding to a position of the manipulation input performed on the touch panel.

  • Patent number: 8774495
    Abstract: When a plurality of images are to be overlapped and synthesized, coincidence degrees between the plurality of images in an area near the boundary of a common area are calculated, and the plurality of images are overlapped and synthesized so that an area near the boundary having a high coincidence degree appears on the overlapped image. Thereby, it is possible to avoid the duplexing of the subject in the common area and unnatural ruptures on the boundary made by the overlapping while reducing the number of processes for the synthesizing.

  • Patent number: 8340464
    Abstract: In a device for combining a plurality of images having a same photograph range, a position shift between the images having the same photograph range is detected, and the position shift of the images is corrected, and after the position shift is corrected, similarity of the respective portions between the images is evaluated, and the image combining method is changed according to the similarity evaluation. Therefore it is possible to create an image having no position shift due to the shaking of a camera and object blurring due to the movement of the object. Moreover, whether the images are combined or not is determined according to the similarity, hence the processing load is reduced and an image having no object blurring can be created.
