20100079483 | Image processing apparatus, image processing method, and program - An image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information. | 04-01-2010 |
20100104211 | Image processing apparatus, image processing method, and computer program - An image processing apparatus includes: ΔΣ modulation means for applying ΔΣ modulation to an image; analog conversion means for converting a signal of the image, whose gradation is converted by the ΔΣ modulation means, into an analog signal; digital output means for outputting a digital signal of the image after gradation conversion; and analog output means for outputting an analog signal of the image after gradation conversion. The ΔΣ modulation means includes arithmetic means for filtering a quantization error; adding means for adding a pixel value of the image and output of the arithmetic means; quantization means for quantizing output of the adding means and outputting a quantized value; and subtracting means for calculating a difference between the output of the adding means and the quantized value. A filter coefficient for the filtering corresponding to the analog output is determined according to a frequency characteristic of the analog conversion means. | 04-29-2010 |

20140078023 | DISPLAY DEVICE, IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM - There is provided a display device including a display unit that displays an image thereon, an eyepiece optical unit that projects a display image of the display unit on the eyes of a user, a correction information retaining unit that retains correction information created in advance according to a state of the user, and a distortion correction unit that corrects distortion of the display image based on correction information according to a current state of the user. | 03-20-2014 |
20140240251 | ELECTRONIC DEVICE - Provided is an electronic device. The electronic device includes a planar display unit, and a touch panel which is disposed so as to overlap the display unit and is capable of detecting a vertical distance between two-dimensional coordinates along a surface of the display unit and a finger. Resolution of the two-dimensional coordinates becomes finer as the vertical distance decreases. Thus, even when the operating finger is immobilized in a state where the electronic device is fixed, a display of a pointer is not wobbled or a display of a screen is not wobbled. In addition, when a line is drawn using a drawing mode, the line is not displayed jaggedly. | 08-28-2014 |

When flattening of the area occupied by the indicator is smaller than a threshold value in which the occupied area is on the predetermined plane spaced apart from the display surface of the display section by a predetermined distance, coordinates of the center of the area are made valid. When the flattening is greater than the threshold value, the coordinates of the center of the area are made invalid. | 09-18-2014 |
