摘要： In executing image processing using low-frequency band evaluation values and high-frequency band evaluation values obtained from an input image, one of a plurality of processors applies the image processing to a partial image assigned thereto using high-frequency band evaluation values obtained from the partial image and low-frequency band evaluation values. This processor distributes, to another processor, low-frequency band evaluation values or a reduced image of the input image to be used by another processor. Another processor applies the image processing to a partial image assigned thereto using high-frequency band evaluation values obtained from the partial image and one selected from the group consisting of the distributed low-frequency band evaluation values and low-frequency band evaluation values obtained from the reduced image, and returns a resultant image.

摘要： The present invention has an object to enable white balance correction appropriate to an image photographed with strobe light-emitting. An image processing apparatus includes: a first correcting unit that corrects image data photographed with strobe light-emitting using a first WEB correction value corresponding to environmental light, and generates a first WEB correction image; a second correcting unit that corrects the image data photographed with strobe light-emitting using a second WEB correction value corresponding to strobe light, and generates a second WEB correction image; a combining ratio calculating unit that obtains a combining ratio of the first and second WEB correction images based on information on a distance to an object photographed with strobe light-emitting and distribution characteristics of the strobe light; and a combining unit that combines the first and second WEB correction images based on the combining ratio.

摘要： An image capture apparatus comprising an image sensor is disclosed. When an instruction to shoot a still image has been detected when executing a live view display, the image capture apparatus shoots the still image preferentially, while repeatedly displaying a same image during a period in which the live view display cannot be updated. The image capture apparatus reduces a luminance and/or changes a tone of the image that is repeatedly displayed.

摘要： An image capturing apparatus comprising an image sensor and a control circuit is disclosed. The control circuit changes, if a second drive period that is a drive period of the image sensor for still image shooting overlaps with a first drive period that is a drive period of the image sensor for moving image shooting, a start timing of the second drive period. When performing still image shooting while performing moving image shooting and moving image display: if the still image shooting is single image shooting or a first shot of continuous shooting, the control circuit does not change the start timing of the second drive period. If the still image shooting is a second shot onward of continuous shooting, the control circuit changes the start timing of the second drive period with giving priority to the moving image display.

摘要： There is provided an image capturing control apparatus. A first control unit performs control to repeatedly obtain an evaluation image using an image sensor. The evaluation image is used to obtain an evaluation value for controlling at least one of image capturing and development. An obtaining unit obtains the evaluation value on the basis of the evaluation image. A second control unit performs control to temporarily stop the obtainment of the evaluation image and use the image sensor to obtain, during a stopped period, a still image for recording. A generating unit generates an estimated evaluation image corresponding to the stopped period on the basis of two or more evaluation images obtained outside the stopped period. For the stopped period, the obtaining unit obtains the evaluation value on the basis of the estimated evaluation image.
