Device for performing image transformation processing and method thereof

A pixel position to be mapped to each pixel position on an output image by deformation is obtained as an input pixel position. A filter coefficient group to be used for pixel interpolation at the time of deformation is adjusted by using the pixel values of pixels positioned around an input pixel position on the input image. A pixel value at the pixel position on the output image which corresponds to the input pixel position is calculated by using the pixel values of the pixels positioned around the input pixel position on the input image and the filter coefficient group after adjustment.

Image processing apparatus, image processing method, and storage medium

An image processing apparatus includes a transformation unit, an identification unit, a determination unit, and a processing unit. The transformation unit is configured to perform transformation processing on an input image based on a transformation parameter. The identification unit is configured to identify transformation information related to amounts of transformation respectively between a first plurality of coordinates on a transformed image generated based on the transformation processing and a second plurality of coordinates on the input image corresponding to the first plurality of coordinates. The determination unit is configured to determine a smoothing parameter related to an intensity of smoothing processing for each region of the transformed image based on the transformation information. The processing unit is configured to perform smoothing processing on an image based on the input image, based on the smoothing parameter for each region.

An image processing apparatus generates image data for projection by applying a deformation process to obtained image data based on an input parameter related to the deformation process. The image processing apparatus prohibits execution of the deformation process if it is determined that a magnification related to the deformation process based on the input parameter with respect to the obtained image data is out of a predetermined range.

Image processing apparatus and image processing method

The distance between projection coordinates to which the center of an image are projected and the center coordinates are added to the projection coordinates to obtain projection center coordinates. The distance is added to the coordinates to which the four corners of the image are projected to obtain projection four-corner coordinates. A distance shorter than the minimum of the distances between the projection four-corner coordinates and the projection center coordinates is decided as an output margin distance. Projection source coordinates to be projected to coordinates apart from the projection center coordinates by the output margin distance are obtained. A maximum of the distances between the projection source coordinates and the projection center coordinates is decided as an input margin distance. Divided images decided based on &#xbd; of horizontal size of the image and the input margin distance are deformed and outputted.

A movie processing apparatus includes an input unit that inputs an input image. A memory control unit stores, in a memory, a deformation image obtained by executing an image deformation process for the input image using a deformation parameter. A determination unit determines, from a memory region in which the deformation image is stored, a readout region to be accessed for obtaining an output image, on the basis of a size of the input image, a size of the output image, and the deformation parameter. A readout unit configured to access the readout region reads out pixel data included in the deformation image. An output unit outputs the image based on the pixel data readout by the readout unit.
