An information processing method comprises: transmitting first image data to an external image processing apparatus and receiving second image data processed by the external image processing apparatus; extracting a feature amount according to a content of image processing performed by the external image processing apparatus from the first image data; and converting the extracted feature amount to displayable information and displaying the information on a display.

Information processing apparatus and method

An apparatus includes at least one memory configured to store instructions, and at least one processor in communication with the at least one memory and configured to execute the instructions to perform same area dividing on each of a plurality of images, and create a composite image from the plurality of images. A first area of the composite image is composited from corresponding areas in a first number of image among the plurality of images. A second area of the composite image is composited from corresponding areas in a second number of image among the plurality of images.

Apparatus, method, and storage medium each relating to image composition

An imaging apparatus includes an imaging element, a readout unit, and a signal processing unit. The imaging element includes pixels that have photoelectric conversion units for one micro lens. The readout unit performs a first readout operation on pixels included in a first region of the imaging element to read signals according to accumulated electric charges, and performs a second readout operation on pixels included in a second region different from the first region to read signals according to accumulated electric charges. The signal processing unit makes a correction for reducing noise levels to the signals readout by the readout unit. The signal processing unit makes the correction to the signals acquired from the first region such that differences between noise levels included in the signals read by the first readout operation and the second readout operation become smaller after the correction by the signal processing unit.

Imaging apparatus, control method of imaging apparatus, and program

An image pickup apparatus includes a first image generatorthat generates a first unit image based on a signal read from the image pickup device with each read cycle of the signal, a detectorthat detects a luminance of the first unit image and detects a luminance variation in a plurality of the first unit images, a second image generatorthat amplifies the first unit image in accordance with the luminance to generate a second unit image if the luminance variation exists, and a controllerorthat generates a focus evaluation signal based on the second unit image to perform a focus control using the focus evaluation signal. The controller does not use the focus evaluation signal based on the second unit image generated from the first unit image in which the luminance is lower than that of a predetermined level for the focus control, and the controller uses the focus evaluation signal based on the second unit image generated from the first unit image in which the luminance is higher than that of the predetermined level for the focus control.

Whether a user of a video camera can discern an unnatural motion or the discernable unnatural motion is permissible is evaluated based on an taken image so as to make a change between mixing of still image shooting driving and maintaining of motion image shooting driving.

Image pickup apparatus for preventing unnatural motion of a motion image

An image pickup apparatus capable of reducing camera-shake blur and rolling-caused distortion of image data obtained by shooting without including invalid data. An object obtained by shooting is stored in a memory area as first image data, and data having a smaller data size than the first image data is acquired as second image data by clipping from the memory area. A clipping position which enables correction of camera-shake blur is calculated according to an amount of movement due to a camera shake. Range information indicative of a range in the memory area and shift amounts used for correcting rolling-caused distortion are calculated. Rolling-caused distortion of the second image data is corrected based on the calculated shift amounts.

An image processing apparatus includes an evaluation value calculation unit configured to acquire an evaluation value from image data, a reduction coefficient calculation unit configured to calculate a reduction coefficient based on the evaluation value, a reduction unit configured to subject the image data to image processing to reduce color bleeding in a target area in the image data based on the reduction coefficient, and a size change unit configured to change the size of the image data. The reduction coefficient calculation unit calculates the reduction coefficient to reduce the color bleeding in a target area in the image data when the evaluation value exceeds a threshold. The threshold is set so that the range of the evaluation value where the reduction coefficient is not calculated when the size change unit sets the size of the image data to a second value larger than a first value is made wider than the range of the evaluation value where the reduction coefficient is not calculated when the size change unit sets the size of the image data to the first value.
