  • Patent number: 10827155
    Abstract: An image processing apparatus is provided to alleviate degradation of the gradation of a color image in the case where images having a sensitivity different from each other are obtained by imaging one same object in black-and-white and color. The image processing apparatus includes a gradation control part obtaining a brightness signal representing a black-and-white image and a chroma signal representing a color image obtained by imaging a same object as that for the black-and-white image and that controls gradation of the chroma signal on the basis of the brightness signal. This configuration can suppress degradation of the gradation of a color image to be minimal in the case where images having a sensitivity different from each other are obtained by imaging one same object in black-and-white and color.

  • Patent number: 10789512
    Abstract: A fusion decision processing section, based on a feature amount calculated by using a monochrome imaged image acquired by imaging a subject with an imaging section, and a color imaged image acquired by imaging the subject from a different point-of-view position with another imaging section, performs fusion decision as to whether or not deterioration of image quality is caused in fusion processing for producing a fusion image obtained by fusion of the monochrome imaged image and the color imaged image with the monochrome imaged image as a reference in a fusion processing section. Moreover, the fusion image data produced in the fusion processing section is selected in a case where deterioration of image quality is not caused in the fusion processing, and demosaic data produced in a demosaic processing section is selected in a case where the deterioration of the image quality is caused in the fusion processing.

  • Publication number: 20200112705
    Abstract: On the basis of a first imaging signal corresponding to a first viewpoint and including white pixels and color component pixels and a second imaging signal corresponding to a second viewpoint different from the first viewpoint and including fewer white pixels than the first imaging signal to increase a rate of the color component pixels in the second imaging signal, a parallax detecting section detects a parallax of the second viewpoint with respect to the first viewpoint. A parallax compensating section performs parallax compensation for the imaging signal for the second viewpoint on the basis of the detected parallax to generate a parallax-compensated color difference signal for the first viewpoint. A fallback determining section and a signal selecting section selects a parallax-compensated second color difference signal or a color difference signal for the first viewpoint to obtain a high-sensitivity captured image while suppressing degradation of the image quality performance.

  • Publication number: 20200007760
    Abstract: There is provided an imaging apparatus and an imaging method, and an image processing apparatus and an image processing method each capable of capturing a high resolution image by effectively using respective pixel signals of a plurality of pixels defined by pupil division immediately below a microlens. A disparity is detected in units of pupil on the basis of respective pixel values of a plurality of divided pixels defined by pupil division. The pixel values of the plurality of divided pixels are added in units of pupil to obtain an added pixel value. The pixel value of the divided pixel and the added pixel value are blended in units of divided pixel in accordance with the disparity. The present disclosure is applicable to an imaging apparatus.
