  • Patent number: 8711239
    Abstract: In a first step of a program, data of a plurality of still images generated by continuously imaging still images of a subject using an imaging apparatus is read into a calculating section. In a second step, the calculating section selects a specified image from among an object image group which includes the plurality of still images and in which respective images are continued in a time base direction. In a third step, the calculating section selects a first image to be added from images before the specified image in the time base direction among the object image group. Further, the calculating section determines an addition rate of the first image to be added to the specified image. In a fourth step, the calculating section records data of the addition rate of the first image to be added in association with data of the specified image.

  • Patent number: 8289411
    Abstract: An apparatus takes in a plurality of still image frames, to generate an interpolated image frame. Next, moving addition of the still image frame and an interpolated image frame is performed in time-axis direction, to generate a superimposed image frame. At this time, high spatial frequency components in the superimposed image frame are suppressed strongly as alienation of motion between the still image frames becomes larger. Movie is reproduced by sandwiching these superimposed image frames between the still image frames. As a result of this, the movie reproduction with smooth motion is made possible even from a group of the still images photographed by an electronics still camera and the like.

  • Patent number: 8159594
    Abstract: A portable telephone device with incorporated projector 10 starts projection by a projection module 6 when a relative angle ? is set to a projection attitude of 80° and three seconds elapses. If a setting is made for performing vibration correction processing, then a camera unit 200 is commanded to start image-capturing or photographing frame pictures continuously. The portable telephone device with incorporated projector 10 calculates six movement vectors by comparing pictures between successive frames photographed by an image sensor. Along with deciding upon “hand tremor” based upon the movement vectors which are calculated, moreover a representative vector is calculated. The portable telephone device with incorporated projector 10 further creates picture shift information for canceling the representative vector, and, if “hand tremor” has been decided upon, suppresses vibration or wobbling of the contents projected by the projector module using the picture shift information.
