TL;DR: In this paper, an image conversion part 30 performs coordinate transformation of a photographed image photographed by an in-vehicle camera 10 into an image representing how a specific area on a ground surface looks from the driving seat of a vehicle.
Abstract: PROBLEM TO BE SOLVED: To enable a driver to intuitively recognize a spatial position of her or his own vehicle. SOLUTION: An image conversion part 30 performs coordinate transformation of a photographed image photographed by an in-vehicle camera 10 into an image representing how a specific area on a ground surface looks from the driving seat of a vehicle. A three-dimensional modeling part 40 creates from a display parameter a three-dimensional model of right and left front wheels in a visual field when the specific area on the ground surface is viewed from the driver's seat of the vehicle. Then, an image composition part 50 composites the three-dimensional model created by the three-dimensional modeling part 40 into an image converted by the image conversion part 30. Moreover, a display 60 displays the image composited by the image composition part 50 instead of the image that has been displayed so far. Thus, the driver can intuitively recognize the spatial relation of her or his vehicle. For example, an effect that decision about clearing of the own vehicle becomes improved when passing through a narrow path or turning a steering wheel quickly in one direction and then the other, can be expected.

Abstract: The invention provides an image conversion method, a signal source device and a display driving device. The signal source device comprises a storage module and an image conversion module, wherein the storage module is provided with a data writing interface and used for receiving and storing an image conversion algorithm written through the data writing interface, and the image conversion module is connected with the storage module and used for converting received original image data with M colors of subpixels into image data of N colors of subpixels according to the image conversion algorithm stored in the storage module and inputting the converted data into a time schedule controller. By means of the signal source device, when a data conversion algorithm needs to be changed, the corresponding data conversion algorithm only needs to be written into the storage module of a signal source, and a time schedule controller chip does not need to be changed.

TL;DR: In this article, a voxel projection is used to generate a projection image including two or more regions which are in a state that is suitable for viewing, and an image conversion is performed in accordance with the display conversion condition set for the region to which each voxels belongs.
Abstract: [Problem] To generate a projection image including two or more regions which are in a state that is suitable for viewing. [Solution] A means (12) for setting regions to be displayed sets at least two regions to be displayed from among three-dimensional image data. A means (13) for setting display conversion conditions sets a display conversion condition for each of the at least two regions set to be displayed. A voxel projection means (14) generates a projection image by carrying out projection processing for voxels corresponding to the regions set to be displayed from among the three-dimensional image data. An image conversion means (15) converts the projection image into a display image by converting voxel values of the voxels projected onto the projection image into pixel values for the display image, said conversion being performed in accordance with the display conversion condition set for the region to which each voxel belongs.
