A first distortion correction unit generates one first output pixel based on two input pixels that are adjacent in a first direction out of a plurality of input pixels included in image data pieces of a captured frame. A second distortion correction unit generates one second output pixel based on two first output pixels that are adjacent in a second direction different from the first direction. The second distortion correction unit successively reads two first output pixels adjacent in the second direction from a storage unit based on input coordinates, which correspond to coordinate values of second output pixels, and generates the one second output pixel by applying linear interpolation processing to the read two first output pixels based on interpolation coefficient.

Image processing device and image capture device

A filtering circuit which filters an image picked up by an image pickup element arranged in a two dimensional array. The filtering circuit includes a plurality of filtering units and a selecting unit. The plurality of filtering units locally filter a plurality of pixels forming the image, and the selecting unit selects one or more pixels to be filtered by one of the filtering units and selects another pixel to be filtered by another one of filtering units. The selected one or more pixels filtered by the one filtering unit and the selected another pixel filtered by another one of the filtering units belong to a same column in the two dimensional array.

Filtering circuit, filter processing method, image pickup element circuit and camera

An image processing system is disclosed that includes a buffer unit configured to store a predetermined pixel and peripheral pixels neighboring the predetermined pixel in image data in a first direction and a second direction perpendicular to the first direction; and a first edge-detecting circuit configured to calculate a maximum value and a minimum value of a set of pixels selected from the peripheral pixels that have the same color as the predetermined pixel to calculate a difference value between the maximum value and the minimum value.

Image processing system that removes noise contained in image data

A defect pixel correction circuit that can easily determine a defect of an image sensor that has the defect that ranges to one direction and replace with the correcting pixel is provided. The defect pixel correction circuitincludes: a defect pixel determination unitconfigured to determine whether a noteworthy pixel oo is a defect pixel referring to a referring pixels ko, mo, qo and so that excludes the noteworthy pixel oo, the referring pixels centering on the noteworthy pixel oo and lining up in one direction; and a defect pixel correcting unitconfigured to generate a correcting pixel value on the basis of the referring pixels mo and qo, and replace the noteworthy pixel value that is pixel value of the noteworthy pixel oo with the correcting pixel value, when the noteworthy pixel oo is a defect pixel.
