Abstract: There is provided an image processing method including detecting a distorted image before correction projected on a screen by a projection-type image display device, searching for a same shape as an input image having a maximum area inside the distorted image, and correcting the input image in a manner that the distorted image becomes the searched-for shape having the maximum area.

Abstract: The present technology relates to an information processing apparatus and method that allow a plurality of projection units to project images more easily in cooperation. The information processing apparatus of the present technology forms a group for projecting one contents data in cooperation with other information processing apparatuses including projection units to project images and imaging units to shoot a subject and obtain shot images, shares correction information as information relating to correction made to images projected by the projection units of the information processing apparatuses belonging to the formed group among the information processing apparatuses belonging to the formed group, and updates the correction information for the subject information processing apparatus on the basis of the shot image obtained by shooting the image projected by the projection unit as a subject and the shared correction information. The present technology is applicable to projectors or cameras, or electronic devices including the both functions of projector and camera, computers controlling these devices, and others, for example.

Abstract: The present disclosure relates to an information processing apparatus and an information processing method for suppressing a decrease in the accuracy of image projection correction. By use of an image projection model using a distortion factor of an fθ lens with an image height of incident light expressed by the product of a focal point distance f and an incident angle θ of the incident light, the posture of a projection section for projecting an image and the posture of an imaging section for capturing a projection plane to which the image is projected are estimated. The present disclosure may be applied, for example, to information processing apparatuses, projection apparatuses, imaging apparatuses, projection imaging apparatuses, projection imaging control apparatuses, or image projection and imaging systems.

Abstract: The present disclosure relates to an image processing apparatus and method, data, and a recording medium by which the invisibility of corresponding point detection can be improved. A pattern picked up image obtained by image pickup, by an image pickup section, of a predetermined structured light pattern projected by a projection section and having a plurality of, for example, patterns 101-1 and 102-2 and so forth, each of which has a luminance distribution of a Gaussian function like, for example, a curve 102-1 or 102-2, disposed therein, is used to detect corresponding points between a projection image projected by the projection section and a picked up image picked up by the image pickup section. The present disclosure can be applied, for example, to an image processing apparatus, a projection apparatus, an image pickup apparatus, a projection image pickup apparatus, a control apparatus, a projection image pickup system and so forth.

Abstract: The present disclosure relates to an information processing apparatus and method that allow an image projection position to be controlled with more ease. Correction information of an image is generated such that the image is projected onto a desired region of a real space. For example, the correction information is generated such that the projected image is located at a desired position as seen from a given viewpoint position. Also, for example, a correction vector is generated that corrects each pixel position of the image as the correction information. The present disclosure is applicable, for example, to an information processing apparatus, a projection apparatus, an imaging apparatus, a projection imaging apparatus, a projection imaging control apparatus, an image projection imaging system, or the like.
