摘要： In one embodiment, an image data acquisition unit, a filter setting unit and a filtering processor are provided. The image data acquisition unit acquires pixel data of first image data of an erect image obtained by a line sensor comprising a plurality of light receiving elements. The erect image is formed by a plurality of gradient index lenses of a lens array. The filter setting unit sets sharpening filter coefficients of a filter to be applied to the pixel data of the first image data corresponding to the respective light receiving elements, according to remainder values obtained respectively by dividing positions of the light receiving elements on the line sensor by an interval of a lens arrangement of the lens array. The filtering processor generates second image data sharpened by applying the obtained sharpening filter coefficients to the respective pixel data of the first image data.

摘要： An interpolated image generating apparatus calculates a motion vector reliability level indicating reliability of a motion vector used for inserting an interpolated image, the value of the motion vector reliability level being determined in such a manner that the stronger the correlation is between a source image area and a destination image area that are brought into correspondence with each other by the motion vector, the larger is the value. The apparatus also calculates a failure-preventing vector reliability level indicating reliability of a predetermined failure-preventing vector used for preventing image failures. The apparatus obtains a motion compensated image based on the motion vector, obtains a failure-preventing image based on the failure-preventing vector, and blends the motion compensated image and the failure-preventing image according to a weighted average thereof calculated by using a weighting factor based on the motion vector reliability level and the failure-preventing vector reliability level.
