An image processing apparatus includes a combining unit configured to combine a visible light image obtained by capturing visible light from an object and a radiation image obtained by capturing a radiation ray that has passed through the object, and an image processing unit configured to change a proportion between the visible light image and the radiation image to be combined by the combining unit such that the proportion differs between combinations in a peripheral region and a central region.

Image processing apparatus and image processing method

There are provided an apparatus capable of complying with arbitrary data acquisition period (frame rate) change instruction without increasing load and cost, and a method and a system for controlling such an apparatus. To realize this, in the present invention, there are included an area sensor for reading out an electric signal accumulated in a plurality of pixels arranged in a matrix, line by line, and a control unit for controlling the area sensor. The area sensor operates in a first operation for deriving radiation image data by reading during irradiation with radiation, and a second operation for deriving the radiation image data by reading during non-irradiation with radiation, alternately. The control unit switches a period for deriving the radiation image data during a time period from an end of the reading in the first operation until an end of the reading in the second operation.

Radiation imaging apparatus, method of controlling the same, and radiation imaging system

The invention provides an image capture and display control apparatus that includes an imaging control unit that operates an image capturing unit at a first time interval so as to obtain a captured image with the image capturing unit and a display control unit that displays the captured image on a display unit, which operates at a second time interval. The apparatus changes at least one of an image capture start timing of the image capturing unit and a processing time from the start of image capturing by the image capturing unit until entering a standby state in which the captured image can be displayed by the display unit, so as to shorten a display delay time, which is caused by the second time interval, from the start of operation by the image capturing unit until display of the image data by the display unit.

Image capture and display control apparatus, image capture and display control method, and image capture and display system

In a display control apparatus, an image receiving portion receives a plurality of images sequentially transmitted from an X-ray imaging apparatus based on a transmission order determined by a transmission-order determining portion, and a capture-order information receiving portion also receives, from the X-ray imaging apparatus, capture-order information indicating a capture order in which each of the images was captured by the X-ray imaging apparatus. The images received by the image receiving portion are stored in an image storage memory. A display controller controls displaying of the images stored in the image storage memory on a display apparatus based on a transmission order for transmitting the images or the capture-order information in accordance with an input imaging condition and an operating status of the X-ray imaging apparatus.

Display control apparatus, radiation imaging apparatus, and radiation imaging system

An imaging apparatus in which positions of an X-ray image and optical image of a subject can be brought into registration with each other is provided. A half-mirror is provided between the X-ray source and subject and is configured to pass X-rays and reflect visible light. A TV camera captures the optical image of the surface of the subject reflected by the half-mirror. A display unit displays the optical image captured by the TV camera together with a reference mark indicating the reference position of this optical image, and displays, in superimposed form, an X-ray image obtained by capturing a prescribed reference object as a subject by using an X-ray imaging unit. An adjusting unit adjusts position and attitude of an X-ray detector in such a manner that the reference object displayed by the display unit will coincide with the reference mark.

Imaging apparatus

An X-ray imaging apparatus includes a visible light imaging unit which captures an image of a visual field region with visible light, an X-ray irradiation unit which irradiates X-rays, an X-ray imaging unit which receives the irradiated X-rays and acquires a radiograph based on the X-rays, and a detection unit which detects an irradiated region irradiated with the X-rays based on the acquired radiograph.

X-ray imaging apparatus, control method for x-ray imaging apparatus, program, and storage medium

A radiation image projection apparatus includes an image acquisition unit for acquiring a radiation image obtained by capturing an image of radiation transmitted through an object and a projection unit for projecting the radiation image as visible light onto the object.
