An image processing apparatus, an image processing method, and a recording medium storing a program for causing a computer to execute the image processing method. The image processing apparatus and the image processing method includes obtaining a captured image captured using a wide-angle lens, detecting movement of an image processing apparatus, converting the captured image into a wide-angle image that at least partially involves a curved plane, calculating an amount of correction according to the movement detected by the detecting, and correcting the captured image by the amount of correction.

Image processing device, image processing method, and recording medium storing program

An apparatus, system, and method of image processing, each of which: acquires a plurality of images respectively captured with a plurality of imaging elements, the plurality of images respectively corresponding to a plurality of frames of a video; calculates, for a current frame, an evaluation value to be used for evaluating each of the plurality of images using a pixel value of at least one pixel in an overlapping area of the plurality of images; determines whether an evaluation value of each of the plurality of images in a frame preceding the current frame is stored in a memory; determines at least one correction target image from the plurality of images based on the evaluation value calculated for the current frame and a determination result indicating whether the evaluation value in the preceding frame is stored; calculates a plurality of correction amounts to be used for correcting a plurality of evaluation values in the overlapping area of the correction target image, based on the evaluation value of the correction target image; and corrects the correction target image based on the plurality of correction amounts.

Image processing apparatus, system, image processing method, and non-transitory recording medium

A reception apparatus for receiving data from a transmission apparatus includes a data receiver configured to receive a synchronization packet including clock information generated by the transmission apparatus and data from the transmission apparatus, a storage memory, storing the received data, a clock adjuster configured to correct a clock of the reception apparatus based on a deviation between a clock of the transmission apparatus and the clock of the reception apparatus by using the clock information generated by the transmission apparatus, a controller configured to control a clock correction amount of the clock adjuster based on a storage amount of data in the storage memory, and a data output circuit configured to retrieve the data from the storage memory to output the retrieved data in synchronization with the corrected clock.

Reception apparatus and system

A map creation apparatus includes an image receiver configured to receive images in time series while moving; a first calculator configured to extract an image area indicating an object from the images and calculate a coordinate of the object in a world coordinate system; a second calculator configured to track the object in the extracted image area with the images and calculate an optical flow of the object; an eliminator configured to calculate a difference in coordinate between vanishing points generated by the movement of the image receiver and the object based on the optical flow, and eliminate the image area of the object from the images when determining the object as a moving object based on the calculated difference; and a storage controller configured to store map information including the coordinate of the object, not eliminated by the moving object eliminator, in the world coordinate system.

Map creation apparatus, map creation method, and computer-readable recording medium

An image coding device encodes image data in units of encoding line number that is number of lines necessary for implementing encoding. The image coding device includes: an image-data transforming unit that transforms image data of lines, number of which is smaller than the encoding-line number, into to-be-encoded image data of the encoding-line number of lines; and an encoding unit that encodes the to-be-encoded image data.
