Abstract

A novel information processing device that is highly convenient or reliable is provided. Alternatively, a novel program that is highly convenient or reliable is provided. The information processing device includes the input/output device that supplies positional information and receives image information and the arithmetic device that receives the positional information and supplies the image information. The arithmetic device determines the contrast or brightness of image information in accordance with the moving speed of the pointer.

Claims

1. An information processing device comprising:

an arithmetic device comprising a memory portion that stores a program; and

an input/output device,

wherein the arithmetic device is configured to receive positional information and supply image information and control information,

wherein the input/output device is configured to supply the positional information and receive the image information and the control information,

wherein the input/output device comprises a display portion that displays the image information and an input portion that supplies the positional information,

wherein the display portion comprises a reflective liquid crystal element and a pixel circuit electrically connected to the liquid crystal element,

wherein the input portion is configured to detect a position of a pointer and supply positional information determined in accordance with the position,

wherein the arithmetic device is configured to determine a moving speed of the pointer in accordance with the positional information, and

wherein the arithmetic device is configured to adjust a contrast or brightness of the image information in accordance with the moving speed of the pointer.

2. The information processing device according to claim 1, wherein the pixel circuit comprises a transistor including an oxide semiconductor.

3. The information processing device according to claim 1, wherein the program comprises:

a first step of initializing setting;

a second step of allowing interrupt processing;

a third step of displaying image information in a first or second mode selected in the first step or the interrupt processing;

a fourth step of determining to move to a fifth step when a termination instruction is supplied and to move to the third step when the termination instruction is not supplied; and

the fifth step of terminating the program,

wherein the interrupt processing comprises sixth to eighth steps;

the sixth step of determining to move to the seventh step when a predetermined event is supplied and to move to the eighth step when the predetermined event is not supplied;

the seventh step of changing a mode; and

the eighth step of terminating the interrupt processing, and

wherein in the first mode in the third step, a contrast of image information when a moving speed of a pointer is higher than a predetermined speed is lower than a contrast of image information when the moving speed of the pointer is lower than the predetermined speed.

4. The information processing device according to claim 1, wherein the program comprises:

a first step of initializing setting;

a second step of allowing interrupt processing;

a third step of displaying image information in a first or second mode selected in the first step or the interrupt processing;

a fourth step of determining to move to a fifth step when a termination instruction is supplied and to move to the third step when the termination instruction is not supplied; and

the fifth step of terminating the program,

wherein the interrupt processing comprises sixth to eighth steps;

the sixth step of determining to move to the seventh step when a predetermined event is supplied and to move to the eighth step when the predetermined event is not supplied;

the seventh step of changing a mode; and

the eighth step of terminating the interrupt processing,

wherein in the first mode in the third step, when a moving speed of a pointer is higher than a predetermined speed, image information having a lower contrast than image information in the second mode is displayed, and when the moving speed of the pointer is lower than the predetermined speed, image information having a higher contrast than the image information in the second mode is displayed, and

wherein in the second mode in the third step, a selection signal is suppled at a lower frequency than in the first mode.

5. The information processing device according to claim 1,

wherein the display portion includes a pixel for displaying blue, a pixel for displaying green, and a pixel for displaying red, and

wherein an area of the pixel for displaying blue is larger than an area of a pixel for displaying a color other than blue.
