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： A pixel interpolation apparatus, an imaging apparatus, a program, and an integrated circuit allow appropriate pixel interpolation processing on an image signal obtained by a single-chip image sensor having a WRGB color filter array. An imaging apparatus includes an imaging unit, a signal processing unit, and a pixel interpolation processing unit. The apparatus calculates a degree of correlation for pairs in two orthogonal directions for an image signal (Raw image) obtained by the imaging unit including a single-chip image sensor having a WRGB color filter array using pixel data in an area around a target pixel, using the correlation degree as a determination criterion in the interpolation processing. The imaging apparatus selectively uses a luminance signal generated from R, G, and B-component signals or a luminance signal generated from a W-component signal to perform pixel interpolation processing with higher accuracy and obtain a YCbCr signal with higher accuracy.

摘要： In an object detection apparatus 1, a window definer 11 defines a window relative to the location of a pixel in an input image 20. A classification value calculator 13 calculates a classification value indicative of the likelihood that a detection target is present in the window image contained in the window based on the feature data of the detection target. A classification image generator 14 arranges the classification value calculated from the window image according to the pixel location to generate a classification image. An integrator 15 integrates the classification image and a past classification image 42 generated from a past input image input prior to the input image 20 to generate an integrated image 45. A determiner 16 determines whether the detection target is present in the input image 20 based on the integrated image 45.

摘要： The object detection device 1 detects an object being recognized (such as a pedestrian) in a frame image 42, and identifies an area 42a where a detected object which is detected in the frame image 42 is present. A frame image 43 is input after the frame image 42. The object detection device 1 detects the object being recognized in the frame image 43, and identifies an area 43a where a detected object which is detected in the frame image 43 is present. When a distance from center coordinates 42b of the area 42a to center coordinates 43b of the area 43a is smaller than a reference distance, the object detection device 1 determines that the detected object which is detected in the frame image 43 is identical to the detected object which is detected in the frame image 42.

摘要： A pixel interpolation processing apparatus and an image capturing apparatus are provided that are capable of performing a pixel interpolation process properly even when the pattern of color filter array is unknown. An imaging apparatus includes an imaging unit having a single-chip image sensor having four-color filter array for obtaining an image signal, and the imaging apparatus uses pixel data for a surrounding area around a target pixel to calculate a plurality of sets of correlation values in two directions orthogonal to each other, and determines the correlation direction based on these correlation values. The imaging apparatus obtains first to fourth color component pixel values for the target pixel relying on the fact that the high-frequency components of pixel signals in a direction orthogonal to a direction with high correlation have high correlation regardless of the color of color filters, thus allowing for performing pixel interpolation processing properly even if the four colors of color filters are unknown.
