摘要： Dithering techniques for images are described herein. An input image of a first bit depth is separated into a luma and one or more chroma components. A model of the optical transfer function (OTF) of the human visual system (HVS) is used to generate dither noise which is added to the chroma components of the input image. The model of the OTF is adapted in response to viewing distances determined based on the spatial resolution of the chroma components. An image based on the original input luma component and the noise-modified chroma components is quantized to a second bit depth, which is lower than the first bit depth, to generate an output dithered image.

摘要： The present disclosure relates to an image displaying method and a display apparatus, wherein each of raw pixels is divided into a plurality of virtual pixels based on desired image resolution for displaying a frame to be displayed; virtual image information for each of the virtual pixels when the image of the frame to be displayed is displayed is determined based on weights of the respective sub-pixels in each of the virtual pixels, weights of the respective sub-pixels in the virtual pixels which are adjacent in rows and the received original image information of the frame to be displayed; thus, each of the virtual pixels displays a color(s) which it lacks itself with the aid of the respective sub-pixels in the virtual pixels which are adjacent in rows, so that the same display function as that of each of the raw pixels may be implemented, and thus the image resolution of the frame to be displayed is increased; and displaying image information required by the respective sub-pixels in each of the raw pixels is determined according to a rule in which a difference between the determined virtual image information and the original image information is minimum; displaying is performed based on the determined displaying image information and the desired image resolution for displaying, so the image of the frame to be displayed can be restored better.

摘要： Disclosed is a video processor for a magnifier camera. In particular, the disclosure relates to a video processor that eliminates the use of a frame buffer. This, in turn, reduces the latency otherwise present in the video signal. The disclosed video processor also allows selected portions of the display to be shaded. This highlights the non-shaded portions of the display while at the same time allowing the entire object to be perceived by the user.

摘要： There is provided an image processing device for generating display image data for displaying a main image and a sub image simultaneously or in a switching manner. The image processing device comprises: a main image data input means (11) for receiving input of main image data representing the main image; a sub image data input means (12) for receiving input of sub image data representing the sub image; a display mode acquisition means (13) for acquiring display mode information indicating a display mode for displaying the main image or the sub image, or both the main image and the sub image simultaneously or in a switching manner; a first feature amount calculation means (25) configured to receive the sub image data input to the sub image data input means (12) or resized sub image data obtained by resizing the sub image data in accordance with the display mode information acquired by the display mode acquisition means (13), and use part or all of the image represented by the received image data to calculate a feature amount regarding image quality of the received image data; an image quality adjustment means (26) for performing image quality adjustment on the resized sub image data to generate adjusted sub image data; a display image data generation means (16) for generating the display image data from the main image data input to the main image data input means (11) and the adjusted sub image data generated by the image quality adjustment means (26), in accordance with the display mode information acquired by the display mode acquisition means (13); and a second feature amount calculation means (51) for calculating a feature amount regarding image quality of the display image data generated by the display image data generation means (16). In a case where the display mode indicated by the display mode information shifts from a simultaneous display mode in which the main image and the sub image are displayed simultaneously or a main image display mode in which only the main image is displayed to a sub image display mode in which only the sub image is displayed, when the image quality adjustment means (26) performs the image quality adjustment on the sub image data corresponding to the sub image display mode after the shift, the image quality adjustment means (26) is configured to perform, based on a reference feature amount obtained from a feature amount of the display image data corresponding to the display mode before the shift calculated by the second feature amount calculation means (51), the image quality adjustment so that a difference between a feature amount of the adjusted sub image data and the reference feature amount is smaller than a difference between the calculated feature amount of the sub image data and the reference feature amount. The reference feature amount is a feature amount that gradually varies from the feature amount of the display image data to a preset value.
