There is provided a display device including a display unit that displays an image thereon, an 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.

Display device, image processing device and image processing method

Provided is a display device including an image display unit configured to display an image with a plurality of pixels arranged on a display surface, an eyepiece optical unit configured to project the display surface of the image display unit in a manner that a predetermined angle of view is obtained, and an image correction unit configured to correct a display image on the display surface at a position of each of representative pixels which are discretely located on the display surface, on the basis of distortion generated due to the eyepiece optical unit.

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.

The electronic device has a display section with a display surface; and a touch panel that is provided while being superimposed on the display section and that can detect an area occupied by an indicator in which the occupied area is on a predetermined plane which is approximately parallel to and spaced apart by a predetermined distance from the display surface of the display section. 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.

Electronic device and method for determining coordinates

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.

Electronic device with touch panel for decreasing pointer wobble

There is a signal processing apparatus, including a gamma correction circuit that performs gamma correction on an input luminance signal and generates an output luminance signal, an output-to-input ratio calculation circuit that calculates a ratio of the output luminance signal to the input luminance signal as an output-to-input ratio of a luminance signal, and a color difference correction circuit that multiplies an input color difference signal by the output-to-input ratio of the luminance signal and generates an output color difference signal. As a result, by correcting the input color difference signal using the output-to-input ratio of the luminance signal, the output color difference signal in which color difference correction has been performed in view of influence of gamma correction can be generated.

Signal processing apparatus, signal processing method, and program

There is provided an image recording device, including: a highly-gradating unit for highly-gradating an input image having a first gradation depth, thereby generating a high gradation image having a second gradation depth higher than the first gradation depth; an image quantizing unit for quantizing the high gradation image generated by the highly-gradating unit such that a quantization error is modulated into a band with relatively low sensitivity of human visual characteristics, thereby generating a recording target image having a third gradation depth lower than the second gradation depth; an encoding unit for encoding the recording target image generated by the quantizing unit; and a recording unit for recording the recording target image encoded by the encoding unit in a recording medium.

Image recording device, image recording method and program

An information processing apparatus includes: a processing system performing processing on an original image; and a gradation conversion section having a gradation conversion function of receiving image data from the processing system, converting a number of bits of the image data, and expressing pseudo grayscales before the gradation conversion in a grayscale converted image, the gradation conversion section being capable of changing the gradation conversion function and performing conversion processing on the image, wherein the gradation conversion section adds and outputs a determination flag indicating whether the gradation conversion processing has been performed at the time of outputting the image data.
