摘要： The present invention makes it possible to stably prevent the development of ringing artifacts while reducing an increase in processing load. An image restoration apparatus (10) reduces a blur developed in an image generated by synthesizing a plurality of input images that are sequentially captured. The image restoration apparatus (10) includes: a PSF obtaining unit (1200) obtaining a first Point Spread Function (PSF) showing blurs which develop across the input images; a PSF transforming unit (1300) processing the first PSF to generate a second PSF, the processing being executed so that, in a frequency domain, an amplitude value for each of frequencies is not smaller than a threshold value; an image converting unit (1400) converting the input images into multiple converted images based on portions (i) of the second PSF and (ii) each corresponding to one of the input images; and an image restoring unit (1500) restoring a degraded image, into which the converted images are synthesized, to generate a restored image, the restoration being executed based on the second PSF.

摘要： The 3D image capture device includes a light-transmitting section with n transmitting areas (where n is an integer and n≧2) that have different transmission wavelength ranges and each of which transmits a light ray falling within a first wavelength range, a solid-state image sensor that includes a photosensitive cell array having a number of unit blocks, and a signal processing section that processes the output signal of the image sensor. Each unit block includes n photosensitive cells including a first photosensitive cell that outputs a signal representing the quantity of the light ray falling within the first wavelength range. The signal processing section generates at least two image data with parallax by using a signal obtained by multiplying a signal supplied from the first photosensitive cell by a first coefficient, which is real number that is equal to or greater than zero but less than one.
