First Claim
1. A drawing device comprising:
- a display device having an image display area;
a sensor arranged in a superimposed relationship with the image display area of the display device and having an indicator operation detection area sized so as to detect indicator operations in the image display area of the display device;
a memory adapted to store drawing information drawn by a user using an indicator on the display device; and
a control circuit that renders a drawing in the image display area of the display device based on the drawing information stored in the memory, andthe control circuit causing a test drawing area and a parameter setting area to be simultaneously displayed superimposed on the drawing in the image display area of the display device in response to a detection, by the sensor, of an indication operation by the user using the indicator, the test drawing area enabling a drawing operation by the user using the indicator in an area falling within the test drawing area and a test drawing image rendered in the test drawing area as a result of the user using the indicator in the test drawing area, the parameter setting area enabling changing of parameters of drawing information generated by the drawing operation in the test drawing area by the user using the indicator,the control circuit causing the test drawing area to be displayed in a visually identifiable manner in the image display area of the display device and causing the test drawing area to be displayed transparently with a portion of the drawing in the image display area of the display device appearing through the test drawing area,wherein the parameter setting area and the test drawing area that are simultaneously displayed superimposed on the drawing in the image display area of the display device are separable from or combinable with each other under control of the control circuit in response to an operation of the indicator.

Abstract
A drawing device includes a sensor arranged in a superimposed relationship with a display device and having an indicator operation detection area sized to detect indictor operations in the image display area of the display device; a memory that stores drawing information; and a control circuit that renders a drawing in the image display area of the display device based on the drawing information stored in the memory. The control circuit causes a test drawing area and a parameter setting area to be displayed superimposed on the drawing image that is displayed in response to a detection, by the sensor, of an indication operation by the indicator, the test drawing area enabling a drawing operation to be performed using the indicator, the parameter setting area enabling changes to parameters of the drawing information generated by the drawing operation in the test drawing area using the indicator. The control circuit causes the test drawing area to be displayed transparently with a portion of the drawing appearing through the test drawing area.

16. A drawing device comprising:
-
a display device having an image display area; a sensor arranged in a superimposed relationship with the image display area of the display device and having an indicator operation detection area sized so as to detect indicator operations in the image display area of the display device; a memory adapted to store drawing information drawn by a user using an indicator on the display device; and a control circuit that renders a drawing in the image display area of the display device based on the drawing information stored in the memory, and the control circuit causing a test drawing area and a parameter setting area to be simultaneously displayed superimposed on the drawing in the image display area of the display device in response to a detection, by the sensor, of an indication operation by the user using the indicator, the test drawing area enabling a drawing operation by the user using the indicator in an area falling within the test drawing area and a test drawing image rendered in the test drawing area as a result of the user using the indicator in the test drawing area, the parameter setting area enabling changing of parameters of drawing information generated by the drawing operation in the test drawing area by the user using the indicator, the control circuit causing the test drawing area to be displayed in a visually identifiable manner in the image display area of the display device and causing the test drawing area to be displayed transparently with a portion of the drawing in the image display area of the display device appearing through the test drawing area, wherein, when the parameter setting area and the test drawing area are simultaneously displayed superimposed on the drawing in the image display area of the display device and are separated from each other, and if, as a result of an operation of the indicator, a distance between the parameter setting area and the test drawing area, separated from the parameter setting area, becomes smaller than a predetermined value, the test drawing area moves, under control of the control circuit, such that the test drawing area is combined with the parameter setting area. - View Dependent Claims (19, 20)
