  • Publication number: 20140333804
    Abstract: An imaging device includes a lens unit, an image sensor, a processing unit, and a display unit. The image sensor is configured to output a first data based on a subject image through the lens unit. The processing unit is configured to correct a distortion of the first data caused by an optical property of the lens unit and to output a second data. The display unit is configured to display based on the second data for each of predetermined lines in a display area. The first predetermined line is a line displayed at a first or last horizontal synchronization time. The second predetermined line is a line displayed at horizontal synchronization time other than the first or last horizontal synchronization time. The first or last horizontal synchronization time is longer than the horizontal synchronization time other than the first or last horizontal synchronization time.

  • Patent number: 8542303
    Abstract: A digital camera includes: an imaging unit that photoelectrically converts light to output a color image; a selecting unit that selects any one identifier from identifiers which are colored in different colors from each other; and a black/white image producing unit that produces a black/white image by weighting gradation values of respective colors for each of pixels of the output color image and adding the weighted gradation values to each other. When the light entered to the imaging unit is entered to a color filter having a color equal to a color of the selected identifier, a correlation between a light amount of light having a wavelength which penetrates the color filer and a light amount of the entered light becomes stronger than a correlation between a light amount of light having a wavelength which is absorbed by the color filter and the light amount of the entered light.
