  • Publication number: 20160142694
    Abstract: In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensor 101 are recorded on a recording device 111 through a conversion processing section 201 and a recording device controlling circuit 210. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuit 203 through a pre-processing circuit 202 and an image being captured is displayed on a display section 112 with a signal for which a camera process has been performed.

  • Patent number: 8810629
    Abstract: An image processing apparatus includes: an image synthesis unit generating a synthesized image by inputting images photographed at different positions and connecting strip areas cut from the images. The image synthesis unit generates a left-eye synthesized image applied to display a 3-dimensional image by connecting and synthesizing left-eye image strips set in the images and generates a right-eye synthesized image applied to display a 3-dimensional image by connecting and synthesizing right-eye image strips set in the images. The image synthesis unit performs a process of setting the left-eye image strip and the right-eye image strip in an allowable range of set positions of the left-eye image strip and the right-eye image strip used to generate the left-eye synthesized image and the right-eye synthesized image, which are at different observing points, applicable to display the 3-dimensional images by acquiring the allowable range from a memory or calculating the allowable range.

  • Publication number: 20130162786
    Abstract: An apparatus and method that generate left-eye and right-eye composition images to display a three-dimensional image maintaining base line length to be substantially constant by connecting stripped areas cut out from plural images. An image composing unit is configured to generate a respective left-eye composition image and right-eye composition image to display respective three-dimensional images by connecting and composing left-eye image strips and right-eye image strips set in each of captured images. The image composing unit performs a setting process of the left-eye and right-eye image strips by changing an amount of offset, which is an inter-strip distance between the left-eye and right-eye image strips, in accordance with image capturing conditions to maintain a base line length corresponding to a distance between capturing positions of the left-eye and right-eye composition images to be substantially constant.

  • Publication number: 20110193941
    Abstract: An image processing apparatus includes an image evaluation unit evaluating properness of synthesized images as the 3-dimensional images. The image evaluation unit performs the process of evaluating the properness through analysis of a block correspondence difference vector calculated by subtracting a global motion vector indicating movement of an entire image from a block motion vector which is a motion vector of a block unit of the synthesized images, compares a predetermined threshold value to one of a block area of a block having the block correspondence difference vector and a movement amount additional value, and performs a process of determining that the synthesized images are not proper as the 3-dimensional images, when the block area is equal to or greater than a predetermined area threshold value or when the movement amount addition value is equal to or greater than a predetermined movement amount threshold value.
