Abstract
An apparatus for obtaining a two-dimensional image of an object by means of an image sensor and a scanning mechanism is provided with a light source for emitting light for irradiating the object. The light source is lighted in response to a request made by a CPU for the commencement of photographing and is allowed to go out after the termination of photographing.
Claims41
An apparatus for obtaining a two-dimensional image of an object, the apparatus comprising:
- a light source for emitting light out of the apparatus to irradiate the object;
- an image sensor for photographing the object by sensing light reflected from the object, the reflected light including the emitted light;
- a scanning mechanism for scanning the object in sync with the photographing;
- and
- a controller for commencing photographing after lighting the light source in response to a request for the commencement of the photographing and for allowing the light source to go out after the termination of the photographing.
An apparatus for obtaining an image of an object, comprising:
- an image pickup device adapted to periodically carry out a scan operation during photographing;
- a light source for emitting light for irradiating the object;
- and
- a controller for controlling the light source so as to allow it to provide a continuous illumination of the object during each scan operation carried out by the image pickup device.
An image input apparatus for scanning an object existing outside of the apparatus by means of an image pickup device and an intermittently driven scanning mechanism, comprising:
- a light source for emitting light outside of the apparatus for irradiating the object;
- and
- a controller for controlling the light source so as to allow it to emit light synchronously with a periodic scan operation carried out by the image pickup device, whereby an image of the object is picked up by the image pickup device while the light source emits light.
A method of obtaining a two-dimensional image of an object by means of an image sensor and a scanning mechanism, comprising the steps of:
- providing a light source for emitting light for irradiating an object to be photographed;
- lighting the light source in response to a request for the commencement of photographing;
- commencing photographing by positioning the scanning mechanism in a plurality of positions such that the image sensor captures a plurality of components of the two-dimensional image of the object during the photographing;
- terminating photographing;
- and
- allowing the light source to go out, wherein the light source provides a substantially continuous light during the photographing.
An imaging apparatus comprising:
- a light source for emitting light to irradiate an object external to the apparatus;
- an image pickup device for capturing an image of a part of the object;
- a scanning mechanism for intermittently changing the part of the object to be captured by the image pickup device;
- and
- a controller for controlling the light source, the image pickup device and the scanning mechanism so that the image pickup device captures the imaging at each changing of the scanning mechanism and the light source emits light at each capturing of the image of a part of the object by the pickup device.
