Abstract: The present invention relates to an imaging device and a method of processing an imaging result in an imaging device, and is applied to e.g. an electronic still camera to thereby allow the camera to correct image quality readily and flexibly with avoiding the deterioration of the image quality effectively. In the present invention, a three-dimensional look-up table is provided and an imaging result (Y2, Cb2, Cr2) is corrected by use of the three-dimensional look-up table.

Abstract: Provided is an image processing apparatus including: a frequency value calculation section that allocates each pixel of an input image to any of respective partial regions obtained by dividing the entirety of a possible range of a luminance value into units in a luminance direction on the basis of the luminance value thereof, and allocates one pixel of the input image to partial regions when calculating frequency values representing the number of pixels allocated to the partial regions with respect to the respective partial regions, to update the frequency values of the partial regions; a characteristic value calculation section that calculates a characteristic value representing a characteristic of the partial region; and a weighted product-sum section that performs edge-preserving smoothing on the input image by weighting and averaging the characteristic values in accordance with a distance in the luminance direction, using the calculated frequency value and the calculated characteristic value.

Abstract: An image processing apparatus includes: a representative value calculation unit calculating a representative value from an input first image signal; an interpolation unit interpolating the representative value calculated by the representative value calculation unit using a second image signal input after the first image signal; and an adjustment processing unit blending the interpolated image signal and the second image signal so that an output ratio of the image signal interpolated by the interpolation unit is smaller when a variation amount of an image corresponding to the second image signal with respect to an image corresponding to the first image signal is large in comparison to a case when the variation amount is small.

Abstract: The present invention relates to an image processing device and method, program and recording medium for achieving grayscale compression capable of suppressing image quality degradation using a simple configuration. A detection section 63 performs a detection process of a signal Y? that has been subjected to the processes of a luminance signal generating section 61 and perception equalization section 62, thus finding average intensities of lighting in bright and dark areas of an input image. A control MPU 64 finds adaptation gains kAr and kBr based on the average intensities. Processing the signal Y? with an edge-preserving LPF 65 provides a lighting component signal Y?lp. A detail extraction section 66 computes the difference between the signal Y? and lighting component signal Y?lp, thus extracting a detail component signal Y?de of the image of the signal Y?.

Abstract: An image processing apparatus that processes input image data includes an exposure-correction-value acquiring unit that acquires exposure correction values at plural stages with respect to an exposure control value during imaging of the input image data, an illumination-component generating unit that generates illumination components on the basis of the input image data, a gain-amount calculating unit that multiplies each of plural weighting coefficients with a multiplication coefficient corresponding to the exposure correction value corresponding to the weighting coefficient and adds up multiplied values to calculate a gain amount, and a gain applying unit that applies, for each of pixels, the gain amount calculated by the gain-amount calculating unit to the input image data.

Abstract: An image signal processing apparatus includes the following elements. A control unit determines a gradation correction characteristic representing a conversion characteristic for correcting brightness of an input frame. A separation unit separates the determined gradation correction characteristic into a representative gradation correction value representing an amount of correction for a representative value of a main subject and a remaining gradation correction characteristic obtained by removing the representative gradation correction value from the gradation correction characteristic. A gain processing unit uniformly applies the separated representative gradation correction value to the frame as a gain. A noise reduction processing unit performs noise reduction processing on the frame to which the representative gradation correction value is applied.
