  • Patent number: 7535595
    Abstract: An image processing apparatus includes a communication unit configured to exchange data with an external device, an attribute determination unit, an embedding unit, and a storage unit. The attribute determination unit determines an image attribute of a first image signal to generate an attribute signal indicating the image attribute. The embedding unit embeds the attribute signal in the first image signal in a predetermined format to obtain a second image signal. The storage unit stores the attribute signal and one of the first image signal and the second image signal. The second image signal is transmitted to the external device through the communication unit.

  • Patent number: 7491562
    Abstract: In a light emitting device, it is preferable that a surface of a film below a light-emitting element has flatness. Therefore, treatment such as planarization of a surface of a film is performed after forming the film. The present invention proposes a structure of a light-emitting device that can make the foregoing planarization easier. The same layer as a wiring formed on a first film is used to manufacture a second film. Herewith, a portion of the first film below a light-emitting element can be prevented from being etched to form unevenness at a surface of the first film during the formation of the wiring. In addition, a surface of a third film is made higher by providing the second film to enable local planarization.

  • Patent number: 7486829
    Abstract: In an image processing apparatus, a pseudo tone processor performs a pseudo tone process by performing an area coverage modulation expression process with respect to M-bit image data, to thereby convert the M-bit image data into N-bit image data, where N is smaller than M. A lossy compressor performs lossy compression with respect to the N-bit image data, by suppressing fluctuations in a pseudo tone processing frequency within a certain range.

  • Patent number: 7466453
    Abstract: An edge area is detected from an image as a first characteristic. It is possible that the first characteristic can not be detected. An edge is detected from the image as a second characteristic. The second characteristic is expanded. When the first characteristic is detected, the first characteristic is set as a third characteristic. When the first characteristic is can not be detected, the second characteristic is set as the third characteristic. Processing such as ink generating/under-color removing or intermediate tone processing or gamma correction is performed based on the third characteristic.

  • Publication number: 20080144975
    Abstract: An image processing apparatus includes a setting unit, a converting unit, and a transmitting unit. The setting unit sets a save-mode for image data to be output to reduce color of image data. When the save-mode is set for image data, the converting unit converts reduces color of the image data to convert the image data into save-mode image data. The transmitting unit transmits the save-mode image data to an external device.

  • Patent number: 7356160
    Abstract: An image processing apparatus embeds decision information that is information about a specific parameter, such as degree of alteration, of an image, into an image signal, and sends the image signal to an external device, such as personal computer, for storage etc. When the image processing apparatus receives the image signal with the decision information embedded in it, the image processing apparatus extracts the decision information from the image signal, determines degree of alteration of the image based on the decision information extracted, sets an image processing parameter based on the degree of alteration determined, and subjects the image signal received to image processing based on the image processing parameter set.
