An image processing apparatus acquires first shape information representing a three-dimensional shape about an object located within an image capturing region based on one or more images obtained by one or more imaging apparatuses for performing image capturing of the image capturing region from a plurality of directions, acquires second shape information representing a three-dimensional shape about an object located within the image capturing region based on one or more images obtained by one or more imaging apparatuses, acquires viewpoint information indicating a position and direction of a viewpoint, and generates a virtual viewpoint image corresponding to the position and direction of the viewpoint indicated by the acquired viewpoint information based on the acquired first shape information and the acquired second shape information, such that at least a part of the object corresponding to the second shape information is displayed in a translucent way within the virtual viewpoint image.

Image processing apparatus, image processing method, and storage medium

A system comprises an obtainment unit that obtains virtual viewpoint information relating to a position and direction of a virtual viewpoint; a designation unit that designates a focus object from a plurality of objects detected based on at least one of the plurality of images captured by the plurality of cameras; a decision unit that decides an object to make transparent from among the plurality of objects based on a position and direction of a virtual viewpoint that the virtual viewpoint information obtained by the obtainment unit indicates, and a position of the focus object designated by the designation unit; and a generation unit that generates, based on the plurality of captured images obtained by the plurality of cameras, a virtual viewpoint image in which the object decided by the decision unit is made to be transparent.

Image processing apparatus that generates a virtual view image from multiple images captured from different directions and method controlling the same

A single composite image is generated by selecting a pixel value for each pixel in any one of a plurality of captured images having been consecutively captured. A motion vector between at least two captured images among the plurality of captured images is calculated. Correction processing is performed, based on a motion vector corresponding to a pixel of interest in the composite image, on the pixel of interest or a pixel near the pixel of interest. The correction processing is performed by updating, using a bright pixel value, a pixel value of at least one pixel in a group of pixels associated with a path from the pixel of interest to a pixel indicated by the motion vector corresponding to the pixel of interest.

The calibration apparatus includes: an image acquisition unit configured to acquire images captured by a plurality of cameras; a vibration detection unit configured to detect vibration of the camera from the images for each of the cameras; an extraction unit configured to extract images captured by the camera whose vibration is within an allowable value and whose position and orientation are regarded as being the same as an image group for each of the cameras; a selection unit configured to select the image groups whose number is larger than or equal to a predetermined number of cameras as a combination; and an estimation unit configured to estimate a position and orientation parameter for each of the cameras by using the selected combination of the image groups.

Calibration apparatus, calibration method and storage medium

A method estimates the distance of a flat part while maintaining the precision needed for estimating the distance in detail. Distance information is estimated by estimating each piece of distance information of an image represented by image data, and distance information represented by resolution-converted image data, and combining the distance information of the image and the distance information of the resolution-converted image.

Distance information estimating apparatus

In generating image data for use in image formation by multi-pass recording, the position of a pixel of interest to be color separated relative to a recording region corresponding to the conveyance distance of a recording medium in one pass of the multi-pass recording is determined, a color separation table corresponding to the result of the determination is selected, and image data of the pixel of interest is color separated using the selected color separation table.

Image processing apparatus and method

A plurality of color data respectively undergo quantization processing, and a logical multiplication of the plurality of quantized color data is calculated. A product of the plurality of color data is calculated. A first low frequency component is extracted from the logical multiplication, and a second low frequency component is extracted from the product. The first low frequency component is subtracted from each of the plurality of color data, and the second low frequency component is added to the subtraction results to generate a plurality of corrected color data. The plurality of corrected color data respectively undergo the quantization processing.
