A first signal processing apparatus includes: an image processing unit configured to at least execute a composition process of generating composed image information in which first image information or second image information and textual information are superimposed; and a control unit configured to control the process of the image processing unit in accordance with communication with a second signal processing apparatus. The control unit selects either one of the first image information and the second image information, and when the second image information is selected, the control unit outputs a first command for instructing the second signal processing apparatus not to superimpose the second image information and the textual information related to the second image information, and causes the image processing unit to generate composite image information in which the second image information and the textual information related to the second image information are superimposed.

Signal processing apparatus and endoscope system with composite image generation

A first signal processing apparatus, to which a first endoscope apparatus including a first image sensor is detachably attached and communicably connected with a second signal processing apparatus to which a second endoscope apparatus including a second image sensor is attached, the first signal processing apparatus being configured to process a first imaging signal generated by the first image sensor or a second image signal generated by the second image sensor, includes a control unit configured to control a process inside the first signal processing apparatus in accordance with communication with the second signal processing apparatus. The control unit processes the first imaging signal when a first command is received, and when a second command is received, the control unit controls the process inside the first signal processing apparatus to make the process of the second imaging signal to correspond to the second command.

Signal processing apparatus and endoscope system

An image processing apparatus processes a first image signal including pixel signals, the first image signal having a picture portion in which a subject is shown and having a blank portion surrounding the picture portion. The apparatus includes: a blank detection unit configured to set similar frames different in size from one another within a display area of a screen representing the first image signal, in a stepwise manner from an outer periphery, and to detect the blank portion based on whether or not a part of the pixel signals belonging to a region outside each of the similar frames has the uniform color or brightness; a region-of-interest setting unit configured to set an initial region-of-interest corresponding to the picture portion in the first image signal, based on the blank portion; and a region-of-interest image generation unit configured to generate a region-of-interest image signal representing the initial region-of-interest.

An image playback apparatus includes: a moving image processing unit configured to generate playback-oriented moving image data from moving image data as a playback target, among moving image data recorded on a recording device; a display controller configured to play back, on a display device, the playback-oriented moving image data generated by the moving image processing unit; a release instruction input unit configured to receive input of a release signal during playback of the playback-oriented moving image data; a still image generation unit configured to generate, from the moving image data, still image data that correspond to a playback image being played back on the display device at a time of input of the release signal; and a recording controller configured to record, on the recording device, the still image data generated by the still image generation unit, in association with the moving image data.

Image playback apparatus and computer-readable recording medium

A display control device comprises an image acquiring unit which acquires observation image data, an image recording unit which records recorded image data, an image synthesizing unit which generates synthesized image data based on the observation image data and the recorded image data, a first selector, a second selector, and a selector interlock controller. The first selector outputs one of the observation image data and the synthesized image data to a first display device as first selected data. The second selector outputs one of the first selected data and the recorded image data to a second display device as second selected data. The selector interlock controller interlocks and controls the first selectorand the second selector

Display control device and endoscope system

A video processor for an endoscope includes an image memory, an image processing unit, a display control unit and a recording unit. The image memory stores, as a sample image, an endoscope image which a user previously acquired. The image processing unit performs the image processing for changing an image quality of the sample image in accordance with a selection value selected by a user and produces a processed image. The display control unit causes a display unit to display the processed image. The recording unit records, as a setting value, a value relating to the selection value determined by the user. The image processing unit performs the image processing, based on the setting value, for the endoscope image.

An image pickup apparatus includes: an image pickup device configured to pick up an optical image formed by an objective optical system and generate an image; a cut-out range setting portion configured to set a cut-out area so that a center comes close to a field-of-view center as a zoom magnification set by an electronic zoom setting portion increases; and a zoom processing portion configured to cut out the set cut-out area from the image, perform enlargement or reduction corresponding to the zoom magnification and generate a zoomed image.

Image pickup apparatus, image processing apparatus, and method for activating image pickup apparatus

An image processing apparatus includes a first input section configured to receive image data including images in a forward field of view and a lateral field of view; an enhancement processing section configured to enhance edges of images corresponding to the image data received; and a boundary correction section provided on a downstream side of the enhancement processing section and configured to perform a correction process non-commutative with an edge enhancement process, the correction process being performed on a boundary region between a forward field of view and a lateral field of view using the image data subjected to edge enhancement.

Image processing apparatus and method for operating image processing apparatus

A processor includes: a data transmission/reception section that reads parameter data unique to a scope from a ROM provided in the scope; a register communication state determination section that determines whether or not the parameter data read from the data transmission/reception section has an error; and a mute control/color bar control section that if a result of the determination by the register communication state determination section indicates that the parameter data has an error, controls an image processing section according to a type of the parameter data having the error.

Video signal processing apparatus for endoscope

In an endoscope apparatus, inside an endoscope, color correction processing is performed that performs multiplication between a color correction coefficient that is set based on a plurality of numerical apertures with respect to a plurality of different wavelengths included in a wavelength band of illuminating light of a light guide that is mounted in the endoscope and that transmits light-source light from a light source apparatus, and at least one of B, G and R signals generated by the signal processing apparatus.
