  • Patent number: 7868923
    Abstract: An optical system forms an optical image on an imager, and a read control block selects a read rule for the imager depending on a magnification addressed by a magnification address block. The imager transforms an optical image at an addressed area into electrical signals in compliance with the read rule. The read image signals are stored in n image memories, where n is the number of images necessary for ultra-resolution processing. Ultra-resolution processing is built up of a motion estimation block and a high-resolution image estimation block adapted to estimate image data having a high-resolution image sequence. A selector selects a basic image for motion estimation and an image that is estimated in terms of motion.

    Abstract: In a dielectric ceramic having crystal grains and containing a perovskite in which the A site contains Ba and the B site contains Ti. as a main component, the crystal orientations are aligned in substantially the same direction within the crystal grains. Some of Ba may be replaced with Ca and/or Sr, and some of Ti may be replaced with Zr and/pr Hf. This achieves a dielectric ceramic which has a high dielectric constant and has favorable AC electric field characteristics in which the change in dielectric constant is small even with changes in applied electric field.

  • Publication number: 20100253796
    Abstract: The invention provides imaging device and high-resolution processing method of image which precisely generate high-resolution image by using image data with a little number of the pixels. An optical system images an optical image in an imaging unit (101), the imaged image is spatially discretized so as to sampled and converted into an image signal, thereby being recorded in a recording unit (105). Further, a timing at which the image is imaged by the imaging unit (101) is recorded in an imaging timing recording unit (107). A weight coefficient for imaged image is calculated by a weight calculating unit (104) by utilizing the timing information obtained by the imaging timing recording unit (107). A high-resolution processing unit (106) generates a high-resolution image by using the weighted information of the image generated by the weight calculating unit (104).
