  • Patent number: 10819882
    Abstract: An image processing device includes: a first color conversion processor configured to perform first color conversion processing on image data; a second color conversion processor configured to perform second color conversion processing on the image data; a coefficient calculator configured to calculate a coefficient indicating a blend ratio between an output of the first color conversion processor and an output of the second color conversion processor; and a blend processor configured to blend the output of the first color conversion processor and the output of the second color conversion processor based on the ratio indicated by the coefficient, wherein the coefficient calculator calculates a position on an xy chromaticity diagram of a color indicated by each pixel in image data processed by the first color conversion processor to determine the coefficient based on a distance from the calculated position to a boundary of a color gamut.

  • Patent number: 10044963
    Abstract: An imaging apparatus includes a rolling shutter type first image sensor and second image sensor, a timing generator that controls operation timings of these two image sensors, and a controller that subjects generated image data to image processing and controls the timing generator. The first image sensor captures an image of a subject to generate first image data, and the second image sensor captures an image of the subject to generate second image data. Each of the first image data and the second image data has a duplicate region in which the subject is partly duplicated. The controller controls the timing generator in such a way that a period over which the first image sensor exposes lines within the duplicate region in the first image data coincides with a period over which the second image sensor exposes lines within the duplicate region in the second image data.

  • Patent number: 9232120
    Abstract: Disclosed is an image processor that reduces or eliminates the effects of a flash band regardless of performing a shutter operation or not. An imaging device includes a flash band detector configured to determine whether each image of the consecutive images shown by image signals output from an imager is a flash band image a part of which is affected by a flash, and a flash band compensator configured to, if a first image is determined as the flash band image, generate a third image which is supposed where the third image is fully affected by a flash by using a second image which is not determined as the flash band image, and output the third image instead of the first image.

  • Patent number: 9117292
    Abstract: The present technique includes: an area-characteristic detector configured to calculate a maximum value, an average value, and a minimum value of signal levels of pixels around a certain pixel; a first gain creating part configured to calculate a first calculation value for the certain pixel; a second gain creating part configured to calculate a second calculation value for the certain pixel; and an adjustment part configured; to perform enhancement by multiplying the difference between the average value and the signal level of the certain pixel by the first calculation value when the signal level of the certain pixel is equal to or higher than the average value, and to perform enhancement by multiplying the difference between the average value and the signal level of the certain pixel by the second calculation value when the signal level of the certain pixel is lower than the average value.

  • Publication number: 20120120068
    Abstract: A display device includes an input unit, a depth direction position information processing unit, and a display processing unit. Depth direction position information is inputted to the input component. The depth direction position information is information corresponding to information about and/or the position in the depth direction of a subject. This depth direction position information is set for at least part of a two-dimensional information corresponding to a subject. The depth direction position information processing unit processes two-dimensional information. The two-dimensional information is made up of depth direction position information and either horizontal direction position information or vertical direction position information. The display processor displays an image corresponding to two-dimensional information processed by the depth direction position information processor.

  • Publication number: 20060209196
    Abstract: A camera recorder that is capable of recording and reproducing a large volume of image data at a high speed and a data recording medium that can be used for the camera recorder are provided. The camera recorder includes a camera portion 1 and a recording portion 2 for recording image data picked up by the camera portion 1. The recording portion 2 includes an interface portion 3 for receiving the image data from the camera portion 1, a plurality of memory cards 50 to 53 for storing the image data, and a controlling portion 4 for controlling writing of the image data to the memory cards 50 to 53. The memory cards 50 to 53 are constituted by a flash memory, and the controlling portion 4 divides the image data received from the camera portion 1 via the interface portion 3 into blocks having a data size that is an integral multiple of a recording block of the flash memory, and records the image data to the memory cards 50 to 53 in parallel.
