Abstract
A medical control device includes: a driving mode switch configured to switch a driving mode of a rolling shutter type image sensor in which a plurality of pixels are two-dimensionally arrayed in units of horizontal lines; and a dimming controller configured to control a light emitting element configured to emit light according to a supplied current, and switch control of the light emitting element according to the driving mode.
Claims20
A medical control device comprising:
- a driving mode switch configured to switch a driving mode of a rolling shutter type image sensor in which a plurality of pixels are two-dimensionally arrayed in units of horizontal lines between a first driving mode that generates no single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed and a second driving mode of long-time exposure in which a plurality of fields are combined to one field to generate a single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed;
- and
- a dimming controller configured to
- control a light emitting element configured to emit light according to a supplied current, and
- on condition that the driving mode is the first driving mode, adjust an electronic shutter of the image sensor during dimming control, or
- on condition that the driving mode is the second driving mode, fix the electronic shutter of the image sensor during dimming control.

A medical observation system comprising:
- an imaging device including a rolling shutter type image sensor in which a plurality of pixels are two-dimensionally arrayed in units of horizontal lines;
- a light source including a light emitting element configured to emit light according to a supplied current;
- and
- a medical controller configured to control operations of the imaging device and the light source, the medical controller including:
- a driving mode switch configured to switch a driving mode of the image sensor between a first driving mode that generates no single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed and a second driving mode of long-time exposure in which a plurality of fields are combined to one field to generate a single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed;
- and
- a dimming controller configured to
- control the light emitting element, and
- on condition that the driving mode is the first driving mode, adjust an electronic shutter of the image sensor during dimming control, or
- on condition that the driving mode is the second driving mode, fix the electronic shutter of the image sensor during dimming control.

A medical observation method comprising:
- switching a driving mode of a rolling shutter type image sensor in which a plurality of pixels are two-dimensionally arrayed in units of horizontal lines between a first driving mode that generates no single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed and a second driving mode of long-time exposure in which a plurality of fields are combined to one field to generate a single line exposure period in which all horizontal lines in an effective pixel area in the image sensor are simultaneously exposed;
- and
- controlling dimming by
- controlling a light emitting element configured to emit light according to a supplied current, and
- on condition that the driving mode is the first driving mode, adjusting an electronic shutter of the image sensor during dimming control, or
- on condition that the driving mode is the second driving mode, fixing the electronic shutter of the image sensor during dimming control.
