摘要： An image capturing apparatus capable of displaying a live view image high in visibility on a high-luminance side. An image capturing section converts light from an object to image signals. An image processor performs image processing on image data formed by the image signals. An operation section receives an instruction for setting a live view mode for realizing a live view function. When an OVF simulation mode is set which is different from a recording live view mode for displaying image data subjected to the image processing on the image display section based on user's photographing settings, photographing is performed under an exposure condition darker than a proper exposure, gradation conversion for compensating for a difference in exposure condition from the proper exposure is performed, and display luminance is controlled to be brighter than display luminance in the recording live view mode.

摘要： A camera body includes an infrared LED that applies infrared light toward a face of a user that is a subject, and an infrared detection camera. The camera body determines a first irradiation amount of the infrared LED and a second exposure condition of the infrared detection camera in accordance with an LED OFF image acquired by capturing an image of the subject in a first exposure condition used by the infrared detection camera without the infrared light applied toward the subject, acquires the LED OFF image and acquires an image (LED ON image) of the subject irradiated with a first irradiation amount in image capture in a second exposure condition used by the infrared detection camera, and detect a face direction of the subject by using a difference image between these images.

摘要： An image capturing apparatus provided with an image capturing unit that captures a first image, a scene discrimination unit that discriminates a scene of an object a candidate generation unit that generates a shooting setting candidate, based on a result of the discrimination, an image generation unit that generates, based on the shooting setting candidate, an image reflecting an effect obtained by the shooting setting candidate, and a display device. The candidate generation unit performs at least one of a first operation for generating a plurality of shooting setting candidates in which a predetermined parameter is separated by greater than a threshold value and a second operation for generating at least one shooting setting candidate based on the result of the discrimination, and the display device preferentially displays the shooting setting candidates generated by the first operation.

摘要： An image pickup apparatus that eliminate manual change of an image pickup direction during picking up an image and can easily obtain an image that records experience while focusing attention on the experience. An image pickup unit picks up a wide-angle image. A face direction detection unit detects a direction of a face of a user. A user movement detection unit detects a movement of the user. A processor executes a set of instructions stored in a memory device to detect a vertical movement and/or a horizontal movement of the face based on an output of the face direction detection unit, determine a position and/or a size of an extraction image extracted from the wide-angle image based on the direction and movements of the face and the movement of the user, and extract the extraction image from the wide angle image with the position and/or the size determined.
