In an image processing apparatus, a face detection unit detects a face area from an input image, and an image processing unit extracts a high luminance area from the face area to generate a correction amount of the high luminance area and corrects the high luminance area using the correction amount. Then, in a case where a plurality of face areas is detected, the image processing unit adjusts the correction amount based on feature information of the plurality of face areas.

A C.I. Pigment Yellow 74 as an insoluble azo pigment is provided. This C.I. Pigment Yellow 74 is crystalline particles. The ratio (26.6&#xb0;/11.7&#xb0;) of a diffraction intensity of a peak at 26.6&#xb0; to a diffraction intensity of a peak at 11.7&#xb0; in terms of Bragg angle (2&#x3b8;&#xb1;0.2&#xb0;) as measured by powder X-ray diffraction using CuK &#x3b1;-radiation is 0.85 to 1.12, and the average primary particle size is 20 to 130 nm. The use of this C.I. Pigment Yellow 74 as a colorant in a coloring composition enables to provide the coloring composition with excellent dispersibility and good particle size stability and storage stability compared with conventional pigments. The use of this coloring composition enables the formation (recording) of images having excellent clarity and transparency of such high levels that have not been achievable by conventional technologies.

When a stepping motor is used as a driving source for a shutter device, if the stepping motor loses synchronization because of variations in load during driving or the like, it becomes unable to rotate a driving ring at that time, and this disables an exposure operation. In a first zone where a driven member is driven, but a light shielding member remains in a closed state or an open state, the motor drives the driven member in open-loop driving mode. In a second zone where the driven member is driven, and thus the light shielding member moves to the closed state or the open state, the motor drives the driven member in feed-back driving mode.

An image processing apparatus determines, when white balance correction is executed on an image signal of a face area detected by face detection unit, based on a first white balance correction value obtained by detecting white pixels, whether the corrected image signal of the face area is present in a second color signal area around a first color signal area indicating a flesh color. When the corrected image signal of the face area is determined to be present in the second color signal area, the image processing apparatus calculates a second white balance correction value for correcting the image signal based on a relationship between the corrected image signal of the face area and the first color signal area.

An image pickup apparatus which can reduce the time required for automatic focus scanning. The size of the face is determined based on information on a subject's face, which is detected from image data acquired by shooting by an image pickup device. The subject distance is estimated based on the determined size of the face. The depth of field is calculated. A range over which the focus lens is driven varies according to the estimated subject distance and the calculated depth of field.
