A display system that makes it possible to obtain high operability while maintaining visibility when a virtual object is displayed. The display system includes a smartphone as an information processing apparatus and smart glasses as a head mounted display that is capable of communicating with the smartphone and has an image capturing section. Information on the smartphone is detected from an image captured by the image capturing section. The smart glasses include a display section that is capable of displaying a virtual object, and a virtual object is displayed on the display section in a position adjacent to the smartphone or in a manner partially superimposing the virtual object on the smartphone, based on the detected information.

Disclosed is an image processing apparatus that generate a plurality of reduced images with different reduction rates from an input image, applies predetermined processing to the reduced images, enlarges the reduced images into their respective original resolutions, and then composes the enlarged images into a composite image. The apparatus applies processing to the input image based on the composite image. The apparatus, depending on a setting, applies the processing to an input image based on the composite image generated from a previous input image.

Image processing apparatus, image processing method, computer-readable medium for performing image processing using reduced image

An image capturing apparatus includes an image sensor in which a plurality of unit pixels are arranged, each unit pixel including one microlens and at least one light receiving portion that produces a pulse signal when light is incident on the light receiving portion, wherein the unit pixel includes a counting circuit capable of counting the pulse signals of a plurality of the light receiving portions.

Image capturing apparatus

An apparatus includes an imaging device including a plurality of light receiving units each converting a light beam into a voltage pulse based on an avalanche effect, and a controller having a processor which executes instructions stored in a memory, the controller being configured to function as a generation unit configured to generate image data based on the voltage pulse, a detection unit configured to detect a focus state of an imaging optical system based on the voltage pulse, and a control unit configured to control an exposure time of the light receiving units. The control unit includes a histogram generation unit and a determination unit. The histogram generation unit generates a histogram of the plurality of light receiving units based on the voltage pulse, and the determination unit determines an exposure state of the plurality of light receiving units based on the histogram generated by the histogram generation unit.

Imaging apparatus

An image capturing apparatus comprises: an image capturing unit; an acquisition unit that acquires at least two images having different exposures; a compression unit that acquires at least two compressed images; a transmission unit that transmits the at least two compressed images; a composition unit that generates a composite image by compositing the transmitted at least two compressed images; and a luminance distribution acquisition unit that acquires luminance distribution information of the composite image, the acquisition unit controlling exposure of the at least two images based on the luminance distribution information acquired by the luminance distribution acquisition unit, and the compression unit performing the compression processing of the at least two images based on the luminance distribution information and the exposure of the at least two images.

Image capturing apparatus, method of controlling same, and storage medium

An image capturing apparatus includes an image sensor having a plurality of pixels and being capable of outputting a plurality of image signals read out using different methods for individually reading out the signals of the plurality of pixels and correction signals for correcting the plurality of image signals, a processing unit for processing the correction signals so as to handle the reading methods for the plurality of image signals, and a correction unit for correcting the plurality of image signals using the correction signals processed by the processing unit.

An electronic device issues a command for setting a function when the function of the electronic device is set by a user by executing software, executes the function in response to the issued command, stores information relating to an invalid function, detects the fact that the issued command is a command for setting the invalid function based on the stored information, and controls so as not to execute the function set by the user in response to the detection that the issued command is a command for setting the invalid function.

Electronic device and imaging apparatus that prevent processing related to an invalid function

This invention makes is possible to protect programs and shorten the activation time of an electronic apparatus even if a non-volatile memory such as an MRAM stores the programs including a boot program, and is used as a main memory. Upon power-on or receiving a reset signal, a program stored in bankof the non-volatile memory is transferred to another bank. Upon completion of the transfer operation, to disable access from the outside of the non-volatile memory to the bankto protect the bank, the bank is set in a disconnection state in the non-volatile memory. A signal indicating completion of the program transfer operation is output to the outside, and a reset-release signal to a processor is generated using the signal as a trigger.

Electronic apparatus

A direction being across the defective pixel and along which pixels used to calculate a signal level of a defective pixel are located, is determined. A ratio between signal levels of pixels that are adjacent to the defective pixel and that have a different color from the defective pixel, and signal levels of pixels that are adjacent to pixels being located along the determine direction with respect to the defective pixel and having the same color as the defective pixel and that have a different color from the defective pixel, is acquired. A value obtained by multiplying an average value of the signal levels of the pixels used to calculate the signal level of the defective pixel by the calculated ratio is output as the signal level of the defective pixel.
