Abstract
A method and an apparatus to determine a class of a medium on which an image is formed. The method includes emitting light to the medium; sensing the light affected by the medium; collecting a first predetermined number of features which are represented by a relationship between a parameter and an intensity of the light and determining the class of the medium using the collected features. One of a light emitting part and a light receiving part move to emit or sense the light, respectively, and the parameter varies with the movement of the light emitting part or the light receiving part.

A method of determining a class of a medium to form an image using an image forming apparatus which comprises a light emitting part that emits light and a light receiving part that senses the light, the method comprising:
- emitting the light to the medium;
- sensing the emitted light which is affected by the medium;
- collecting a first predetermined number of features which are represented by a relationship between a parameter of the medium and an intensity of the light sensed by the light receiving part;
- and
- determining the class of the medium using the collected features,
- wherein one of the light emitting part and the light receiving part moves to emit or sense the light, and the parameter varies with the movement of the light emitting part or the light receiving part.
An apparatus to determine a class of a medium on which an image is formed, the apparatus comprising:
- a light emitting part which emits light to the medium;
- a light receiving part which senses light affected by the medium;
- a carrier which moves with the light emitting part or the light receiving part in response to a movement control signal;
- a feature collector which collects a first predetermined number of features of the medium;
- and
- a media class discriminator which determines the class of the medium using the collected features,
- wherein the features are represented by a relationship between a parameter of the medium, which varies with the movement of the carrier, and an intensity of the light sensed by the light receiving part.
A method comprising:
- moving an emitter to emit light to a recording medium or a sensor to sense the light affected by the recording medium;
- collecting features which are represented by a relationship between a parameter of the medium and an intensity of the sensed light;
- and
- determining a class of the medium using the collected features,
- the parameter varying with the movement of the emitter or the sensor.
A method comprising:
- moving an emitter to emit light to a recording medium or a sensor to sense the light affected by the recording medium;
- determining intensities of the affected light at a plurality of angles;
- and
- determining a class of the medium according to the determined intensities.
A method comprising:
- providing a single emitter to emit light to a recording medium and a single sensor to sense the light affected by the recording medium;
- collecting features which are represented by a relationship between a parameter of the medium and an intensity of the sensed light;
- and
- determining a class of the medium using the collected features.
