  • Patent number: 9727993
    Abstract: An in-image capturing unit captures an image of a subject in a direction facing a front surface of an image processing apparatus, as an in-image, and an out-image capturing unit captures an image of a subject in a direction facing a back surface of the image processing apparatus, as an out-image. A signal processing unit obtains a binary image as additional information, the binary image being obtained by binarizing the in-image, for example, and adds the additional information to image data of the out-image. Additionally, the signal processing unit combines the binary image serving as the additional information with the out-image when the out-image is reproduced, and displays the resultant image. In such a manner, information obtained from the in-image is added to the out-image as additional information, and thus it is possible to more effectively display an image and improve convenience.

  • Patent number: 9445022
    Abstract: An apparatus for and a method of executing noise reduction processing and defect compensation processing on an image in an RGBW arrangement are provided. In pixel value compensation processing of a color pixel that makes up image data in the RGBW arrangement that has each color pixel of R, G, and B and a white (W) pixel, the W pixel is interpolated at a position of an attention pixel that is a compensation target, and at a position of a reference pixel which has the same color as an attention pixel within a reference area, smoothing weight is calculated based on each pixel value of the interpolation W pixel, and thus a compensation pixel value of the attention pixel is calculated by executing smoothing processing to which the calculated smoothing weight is applied. Moreover, by applying the W pixel in the neighborhood of the color pixel, it is determined whether or not the color pixel is in a texture area, and only if the color pixel is not in the texture, defect compensation processing is executed.

Remosaic processing for inputting, as an input image, a mosaic image in which pixel blocks configured of a plurality of same-color pixels are arrayed, and converting the pixel array of the input image into a different pixel array is executed. In this remosaic processing, from among constituent pixels of the input image, pixel value gradients in eight directions in a conversion-target pixel location that is targeted for color conversion processing are detected, an interpolated pixel value calculation mode for the conversion-target pixel is decided on the basis of the pixel value gradients in the eight directions, and an interpolated pixel value for the conversion-target pixel location is calculated in accordance with the decided processing mode.
