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 ?) in the point image restoration process for the IR data captured with radiation of near-infrared light is higher than restoration strength (first gain ?) in the point image restoration process for the luminance data Y.

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: 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: An image capture device provided with a first memory unit, which memorizes position information of non-continuous defective pixels of a solid-state image capture component, and a second memory unit with a higher access rate than the first memory unit, which memorizes position information of continuous defective pixels. When a continuous photography mode or a video photography mode is set, defective pixel correction processing is carried out on image data corresponding to each of defective pixels according to the defective pixel position information stored at the second memory unit. Alternatively, when a still photography mode is set, image data corresponding to all defective pixels is corrected, based on both the defective pixel position information stored at the first memory unit and the defective pixel position information stored at the second memory unit. As a result, it is possible to correct defective pixels with high efficiency in accordance with conditions of photography.

Abstract: A digital still camera has a CCD image sensor, which includes an active pixel area for image pickup of an image to produce image data. A black pixel area is disposed outside the active pixel area, and produces black pixel data. The image pickup apparatus includes an amplifier for adjusting white balance of the image data. A smear detection unit detects a smeared portion of a smear phenomenon in the image according to the black pixel data. A tone correction unit reduces chroma of the image in a predetermined hue area according to a smear level of the smear phenomenon determined from the black pixel data, to carry out color correction of the smeared portion for the image data after adjusting the white balance.
