Embodiment Construction

[0052] Hereinafter, as a mode for implementing the present invention (hereinafter referred to as "embodiment"), a medical endoscope system that captures and displays images of the inside of a body cavity of a subject such as a patient is taken as an example of an imaging system. Be explained. In addition, the present invention is not limited by this embodiment. Furthermore, in the description of the drawings, the same reference numerals are assigned to the same parts. Furthermore, the drawings are schematic, and it should be noted that the relationship between the thickness and width of each member, the ratio of each member, and the like are different from actual ones. Moreover, the part which differs in size and a ratio also is included among drawings.

[0053] figure 1 It is a diagram showing a schematic configuration of an endoscope system 1 according to an embodiment of the present invention. figure 2 It is a block diagram showing the functional configuration of main...

Abstract

Provided are an imaging device and an imaging system capable of specifying abnormalities in the imaging device in detail. The imaging device has: a sensor part (244a), which has a light receiving part (244f), and can read out an electric signal generated by the light receiving part (244f) as image information, and the light receiving part (244f) is provided with a device for photoelectrically converting the received light respectively. A plurality of pixels that generate photoelectrically converted electrical signals; a control unit (244e), which controls the output mode of the electrical signals output by each pixel in units of pixels, and outputs electrical signals corresponding to a prescribed display pattern; the AFE unit (244b) which performs signal processing on the electrical signal output by the sensor part (244a); and a transmitting part (P / S converting part (244c)) which transmits the processed signal processed by the AFE part (244b) to the outside.

Description

technical field [0001] The present invention relates to, for example, an imaging device and an imaging system capable of outputting a photoelectrically converted electrical signal as image information from a pixel arbitrarily designated as a readout target among a plurality of imaging pixels. Background technique [0002] Conventionally, in the medical field, an endoscope system is used for observing organs of a subject such as a patient. The endoscope system has: an insertion part, which is, for example, flexible and elongated, and inserted into the body cavity of a subject; and a display unit capable of displaying an in-vivo image captured by an imaging element. When using an endoscope system to acquire in-vivo images, after inserting the insertion part into the body cavity of the subject, the living tissue in the body cavity is irradiated with illumination light such as white light from the front end of the insertion part, and the imaging element performs the in-vivo ima...
