  • Patent number: 10999562
    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: 20210074243
    Abstract: There is provided an image processing device, an image projection device, a control device, an information processing device, an image projection system, an image processing method, and a program that make it possible to suppress a reduction in a subjective image quality. On the basis of each frame image of a moving image, a time during which a projection image of each frame image of the moving image is viewable by a user is controlled. For example, a controller controls the time during which the projection image is viewable by the user, to cause a difference between the moving image and the projection image due to a reduction in a luminance and a difference between the moving image and the projection image, which increases due to an increase in the time during which the projection image is viewable by the user, to be suppressed.

  • Publication number: 20200302881
    Abstract: Effective image correction processing for reducing flicker is executed according to characteristics of images, and an image to be displayed in a liquid crystal display apparatus is generated. Characteristic amount change rate data that is a change rate between a characteristic amount of a sample image and a characteristic amount of a sample image output to a liquid crystal display device is acquired in advance and stored in a storage unit. The correction parameter for reducing flicker is calculated on the basis of the characteristic amount of the image to be corrected and the characteristic amount change rate data of the sample images stored in the storage unit. The correction processing to which the calculated correction parameter has been applied is executed for the image to be corrected to generate a display image. As the characteristic amount, for example, the interframe luminance change amount, the interline luminance conversion amount, or the interframe motion vector is used.

  • Publication number: 20190355097
    Abstract: There is provided an apparatus and a method that perform a process of improving the quality of a low-quality image such as a far-infrared image. The apparatus includes an image correction unit that repeatedly performs an image correction process using a plurality of processing units in at least two stages. The image correction unit inputs a low-quality image to be corrected and a high-quality image which is a reference image. Each of the processing units in each stage performs a correction process for the low-quality image, using a class correspondence correction coefficient corresponding to a feature amount extracted from a degraded image of the high-quality image. A processing unit in a previous stage performs the correction process, using a class correspondence correction coefficient corresponding to a feature amount extracted from an image which has a higher degradation level than that in a processing unit in a subsequent stage.
