A medical signal processing apparatus processes image signals input from an imaging device. The image signals corresponds to a result of examining a subject, and the imaging device sequentially outputs the image signals from multiple pixels arrayed in a matrix according to a raster to the medical signal processing apparatus. The medical image signal processing apparatus includes: a signal divider configured to divide the image signals according to the raster sequentially output from the imaging device into first divided image signals each according to a pixel group consisting of multiple pixels arrayed in connected multiple columns; and a plurality of pre-processors configured to process, in parallel, sets of pixel information of the multiple first divided image signals divided by the signal divider.

Medical signal processing apparatus and medical observation system

An endoscope system is disclosed that included a camera head, a detection unit, and a distortion correction processing unit. The camera head is detachably connected to an eyepiece unit of a plurality of types of endoscopes inserted into a subject, the camera head including an imaging unit that captures a subject image received from an endoscope among the plurality of types of endoscopes that is connected to the eyepiece. The detection unit that detects a size of the subject image in the captured image on the basis of a luminance signal of each pixel in the captured image obtained by the imaging unit. The distortion correction processing unit that corrects an optical distortion of the captured image depending on sizes of a plurality of different subject images.

Endoscope system and circuitry that corrects distortion based on image size

There is provided a medical stereoscopic observation device, including: an acquisition section that acquires a first signal associated with a first imaging section and a second signal associated with a second imaging section via mutually different transmission channels; and a switching section that switches a signal to use for a certain control between the first signal and the second signal, in accordance with a state of the transmission channel for transmitting the first signal.

Medical stereoscopic observation device, medical stereoscopic observation method, program, and medical stereoscopic observation system

An image-signal processing apparatus () designed to process the signals output from a CCD image sensor () that reads pixel data for one screen, line by line, divides the pixel data into a plurality of channels and outputs the pixel data thus divided. The image-signal processing apparatus () detects and corrects the black level of each pixel data item that the image sensor () has output for one channel. The image-signal processing apparatus () detects and corrects the gain difference between channels, which pertain to the pixel data items output from the image sensor (). Hence, the apparatus () can correct the black level of each pixel data item and the gain difference between channels with high accuracy, when used in combination with an image sensor that divides pixel data into a plurality of channels.

Image-signal processing apparatus for use in combination with an image sensor

A pixel defect detecting and correcting apparatus and method for detecting and correcting defects where the number of correctable defect pixels is not restricted to the capacity of a memory. The apparatus includes a color difference and luminance calculating block which calculates the absolute values of the color differences of adjacent pixels and a defect judgment target pixel, and color difference and luminance data. The apparatus also includes a maximum and minimum data values detecting block; a color difference interpolated value calculating block and a luminance interpolated value calculating block which obtain the color difference interpolated values and luminance interpolated values of the defect judgment target pixel.
