摘要： An imaging device includes: a capturing unit that captures a motion picture at one of a plurality of frame rates; a buffer that temporary stores the motion picture captured by the capturing unit; a signal generation unit that generates a signal used for specifying a core frame that is to be subjected to a resolution enhancement processing, while the capturing unit captures the motion picture at a first frame rate; a capturing control unit that controls the capturing unit to capture the motion picture, after the core frame specified by the signal, at a second frame rate that is higher than the first frame rate; a reference frame determination unit that determines a frame stored in the buffering unit at the second frame rate as a reference frame; and an image processing unit that performs the resolution enhancement processing by converting the core frame into a high-resolution frame by reference to the reference frame determined by the reference frame determination unit.

摘要： An image resolution increasing method includes reducing an input image, calculating a first feature vector having a feature quantity of a first block of a reduced image, extracting a high-frequency component image from the input image, storing pairs each having the first feature vector and a second block of the high-frequency component image that is located at the same position as the first block as a look-up table, enlarging the input image, calculating a second feature vector having a feature quantity of a third block of an object in the input image, searching the look-up table for the first feature vector similar to the second feature vector, and adding a fourth block of the look-up table which pairs with the first feature vector and a fifth block of the temporal enlarged image that is located at the same position as the third block.

摘要： According to one embodiment, an image processing apparatus includes a calculation unit. The calculation unit calculates a reliability for each of pixel areas in such a manner that the reliability increases with increasing at least one of (1) a first evaluation value which increases with increasing planarity, in a color space, of a distribution of pixel values in each of the pixel areas, (2) a second evaluation value which increases with increasing wideness of pixel values in each of the pixel areas on an estimated plane approximating the distribution of the pixel values in each of the pixel areas in the color space, and (3) a third evaluation value which increases with decreasing distance between the estimated plane and an origin of the color space.

摘要： An image processing device includes: a first edge strength calculation part that calculates a first edge strength for a focus pixel based on pixel values in a first region that includes the focus pixel in an input image; a second edge strength calculation part that calculates a second edge strength for the focus pixel based on pixel values in a second region that is smaller than the first region and that includes the focus pixel; and a filter processing part that determines a filter coefficient such that a first smoothing strength is higher than a second smoothing strength and that filters the input image using the filter coefficient. The first smoothing strength is obtained where the first edge strength is higher than a first reference value and where the second edge strength is lower than a second reference value, and the second smoothing strength is obtained in other cases.
