摘要： An imaging apparatus includes an imaging unit, a signal processing unit, and a pixel interpolation processing unit. The apparatus calculates a correlation degree for pairs in two orthogonal directions for an image signal obtained by the imaging unit including a single-chip image sensor having a four-color filter, such as a WRGB color filter, using pixel data in an area around a target pixel, using the correlation degree as a determination criterion in the interpolation. When a color component pixel with an identical color of a color component pixel subjected to pixel interpolation is not located in the direction having the high correlation, the pixel interpolation apparatus changes ratio in a direction orthogonal to the direction having the high correlation by using a pixel value resulting from color space conversion in the direction orthogonal to the direction having the high correlation, and performs pixel interpolation based on the change ratio.

摘要： Important information about an object is detected using less arithmetic processing. An object detection unit generates an edge image from a color image. The object detection unit evaluates symmetry of an image included in the edge image by performing processing in accordance with the position of a target pixel. The object detection unit identifies a symmetry center pixel forming an object having symmetry. The object detection unit detects an object width for each symmetry center pixel. The object detection unit identifies the width of the object in the vertical direction based on the width of the symmetry center pixels in the vertical direction, and identifies the width of the object in the horizontal direction based on the object width identified for each symmetry center pixel.

摘要： A compressed data generator compresses, by using a lossless compressor and a lossy compressor, image data in units of first blocks to generate a plurality of types of compressed data. A selector performs selection processing in units of second blocks each including a predetermined number N of first blocks, where N is an integer of 1 or more. The selection processing involves determining whether each of the plurality of types of compressed data satisfies a selection condition and selecting one piece of compressed data that satisfies the selection condition. The selection condition includes a data size condition that a data size of all the first blocks included in the second block is less than or equal to a predetermined value, and a data accuracy condition that information maintaining accuracy is highest among compressed data that satisfy the data size condition.

摘要： It is an object of the present invention to achieve an object detection apparatus, a program, and an integrated circuit each of which is capable of appropriately detecting an axially symmetric object in an image, whatever image is to be processed, without performing any complicated thresholding. The object detection apparatus includes a processing object region determination unit, a variance acquisition unit, a matching determination unit, and an object region detection unit. The processing object region determination unit sets a symmetry axis in an image region included in an image and divides the image region into a determination image region and a reference image region so as to be line symmetric with respect to the symmetry axis. The variance acquisition unit acquires a degree of variance of image feature amount in the image region. The matching determination unit acquires a matching value between the determination image region and the reference image region and determines the symmetry between the determination image region and the reference image region with respect to the symmetry axis on the basis of a corrected matching value which is obtained by correcting the acquired matching value in accordance with the degree of variance. The object region detection unit detects an image region which is line symmetric with respect to the symmetry axis on the basis of a determination result from the matching determination unit.
