The accessory apparatus includes an accessory communicator providing a notification channel (RTS), a first data communication channel (DCL) and a second data communication channel (DCL). The accessory controller transmits, in a transmission request receiving state of receiving a transmission request from an image-capturing apparatus through the notification channel, accessory data to the image-capturing apparatus through the first data communication channel, and receives camera data transmitted through the second data communication channel from the image-capturing apparatus in response to receiving the accessory data. The accessory controller stops, in the transmission request receiving state and during transmission of the accessory data to the image-capturing apparatus, in response to becoming a non-transmission request receiving state, transmitting the accessory data to the image-capturing apparatus.

An image processing apparatus includes a memory that stores instructions and a processor that executes the instructions to cause the image processing apparatus to function as a refocused-image generating unit generating a refocused image having a focus position changed by using image data including information indicating a direction and an intensity of a light beam entered from an object, and a depth-of-field setting unit setting a depth of field of the refocused image to be used for reproduction of a moving image based on a type of reproduction mode relating to the reproduction of the moving image.

Image processing apparatus, image processing method, and storage medium

An image processing apparatus functions as an image data generating unit that generates image data based on a signal received from an image pickup element including a unit pixel including a plurality of pixels allocated to each of a plurality of microlenses, a frame image generating unit that generates a frame image for reproduction of a moving image based on data, within the image data, read from a predetermined read region of the unit pixel, and a changing unit that changes the predetermined read region of the unit pixel for the frame image generating unit depending on a reproduction mode relating to the reproduction of the moving image. The reproduction mode comprises a normal reproduction mode and a search reproduction mode. A moving image reproduction speed for the search reproduction mode is higher than a moving image reproduction speed for the normal reproduction mode.

An image processing apparatus detects a focus state of obtained LF data, and changes methods for recording the LF data, depending on the focus state. At this time, the image processing apparatus records a reconstructed image generated from the LF data without recording the LF data when the focus state of the LF data is an in-focus state, and records the LF data when the focus state of the LF data is in an out-of-focus state.

Image processing apparatus, control method, and recording medium for processing an image signal for which a focus state can be changed after image capture

An image pickup apparatus includes a plurality of pixels, a readout circuit configured to read out pixel signals from the pixels for each pixel row, an analog to digital (AD) converter configured to adjust an AD conversion gain depending on an output level of the readout circuit and to provide a signal from the readout circuit with an AD conversion to output image data, and a controller configured to control the AD conversion gain of the AD converter depending on a predetermined condition.

Image pickup apparatus and image pickup system with ad converter outputting image data at first resolution in a case where pixel signals are not higher than threshold level and at second resolution in a case where pixel signals are higher than threshold level
