Abstract: Provided is an imaging device that prevents glare resulting from light that leaks out from a subject display area of a display section in an OVF mode.A finder device can be switched between the OVF mode and an EVF mode. A subject display area and an information display area are set in an EVFLCD. In the OVF mode, nothing is displayed in the subject display area of the EVFLCD, and an information image is displayed in the information display area. An EVF shutter is set such that the light transmittance of a first area, which corresponds to the subject display area, becomes a low transmittance and the light transmittance of a second area, which corresponds to the information display area, becomes a high transmittance. The first area, which is set at low transmittance, blocks light that leaks from the subject display area.

Abstract: A distance-information acquisition unit acquires information about a distance to a subject in each focus detection region by setting a plurality of focus detection regions in an imaging region. A depth-of-field calculating unit calculates the depth of field for one major subject (principal object) on the basis of the information about a distance to the major subject, which is selected from a plurality of subjects, and a diaphragm value, which is corrected on the basis of optical characteristics of an APD filter. An insertion/retreat control unit determines whether or not a subject other than the major subject is present outside the depth of field on the basis of the information about the distance and inserts the APD filter onto the light path in a case in which the subject other than the major subject is present outside the depth of field.

Abstract: According to the present invention, even if variation (estimation variation) is caused in a subject distance estimated at the time of imaging when restoration processing of a taken image is performed using a restoration filter corresponding to the subject distance, since an optimal restoration filter that conforms to a subject distance taking into account the maximum infinity-side estimation variation and does not cause overcorrection is selected, it is possible to prevent resolution degradation due to overcorrection and achieve the improvement of resolution by the restoration filter.

Abstract: For a mosaic image in a repeated cycle with “I”דJ” (“I” and “J” are integers of 2 or more) pixels, a color mix ratio is stored in a memory unit by being associated with a pixel position in I×J pixels so that a color mix ratio A associated with a pixel position in I×J pixels of an object pixel for mixed color correction is read from the memory unit, and a mixed color component included in the object pixel is removed based on the color mix ratio A and a color signal of the object pixel to calculate a white balance gain based on a color signal of each of pixels in the mosaic image for which the mixed color correction is applied.

Abstract: An image processing device and an image processing method capable of satisfactorily performing a point image restoration process of a visible light image and a point image restoration process of a near-infrared light image are provided. A point image restoration process is performed on luminance data Y indicating a visible light image and IR data indicating a near-infrared light image using a first point image restoration filter based on a first point spread function with respect to visible light of an optical system and a second point image restoration filter based on a second point spread function with respect to near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data so that restoration strength (second gain β) in the point image restoration process for the IR data captured with radiation of near-infrared light is higher than restoration strength (first gain α) in the point image restoration process for the luminance data Y.

Abstract: According to the present invention, when restoration processing of a taken image by the use of a restoration filter corresponding to a subject distance is performed, by storing only a corresponding restoration filter in a subject distance range between the estimation variation close range and the infinity such that a restoration filter in a range on the nearer side than the estimation variation close range is not provided from the beginning, it is thereby possible to reduce the number of restoration filters held beforehand.
