In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image.
An image processing circuit, such as a graphics accelerator chip or any other suitable circuit, includes display output control logic that is operative to receive a current frame of information from a frame buffer and is operative to process a current frame, such as by providing gamma correction, image scaling, graphics or video overlaying, or other suitable processing, to produce a processed current display frame and stores the processed current display frame back in the frame buffer. Fixed function or dedicated, display type specific temporal processing logic receives the processed current display frame stored in the frame buffer and also obtains at least one previous processed current display frame from the frame buffer and temporally processes pixels from each of the processed current display frame and the previous processed current display frame to produce a temporally compensated display frame for a specific type of display.
An image processing apparatus includes: a global motion estimation apparatus that performs global Motion Estimation on current and reference images and then outputs a Motion Vector, wherein the global motion estimation apparatus includes a motion estimationprocessing unit that has a function of executing an LK method two or more times across a whole screen to perform the global motion estimation between the current and reference images; and the motion estimationprocessing unit obtains a set of motion vectors based on at least information about pixel value variations and information in which a calculation result of an arbitrary calculation expression is added across a whole screen in first motion estimation, and determines whether to perform addition on each pixel according to a set condition when obtaining the at least information, and obtains and outputs a new set of motion vectors as a result of a second LK method when the condition is satisfied in second motion estimation.
An electronic endoscopesystem for observing living tissues inside a body cavity includes an illuminating apparatus having a white light source emitting white light and an excitation light source emitting excitation light, an electronic endoscope including an insertion part to be inserted into the body cavity, an imaging device that receives an optical image and outputs image signals corresponding to the optical image, an image forming system that forms the optical image, an operating pant provided at a rear anchor of the insertion part, and a plurality of operable members arranged at the operating part, a display device, an image processingsystem that receives the image signals outputted from the imaging device, the image processing system obtaining a normal image when the living tissues are illuminated with the white light and a fluorescence image when the living tissues are irradiated with the excitation light, and a control system that controls the whole of the electronic endoscope system. The control system assigns a function to one of the plurality of operable members for switching between a normal mode for observing the normal image and a fluorescence mode for observing the fluorescence image. The control system assigns different functions between the normal mode and fluorescence mode to at least one of the others of the plurality of operable members.
An image processing apparatus includes a size reducing unit that reduces sizes of a plurality of continuous images, which are still images obtained by continuously capturing images of a moving object, to thereby generate reduced continuous images; a maskgenerating unit that extracts moving object regions from the reduced continuous images, to thereby generate reduced moving object extraction mask images; a size restoring unit that enlarges the reduced moving object extraction mask images to the same size as original sizes of the continuous images that are not reduced by the size reducing unit, to thereby generate moving object extraction mask images; and a combining unit that extracts the moving object regions from the continuous images by using the moving object extraction mask images to thereby obtain moving object images, and combines the moving object images in a predetermined one of the continuous images.
An image processing apparatus includes an image acquiring unit (390) for acquiring a captured image including a picture of a subject through imaging by an imaging unit (200), a distance information acquiring unit (340) for acquiring distance information based on the distance from the imaging unit (200) to the subject during imaging, a known-characteristic information acquiring unit (350) for acquiring known-characteristic information which is information indicating a known characteristic relating to a structure of the subject, and an unevenness specifying unit (310) for performing unevenness specification processing for specifying an uneven part of the subject that matches a characteristic specified by the known-characteristic information from the imaged subject on the basis of the distance information and the known-characteristic information.
