  • Patent number: 11216563
    Abstract: Systems for performing a security assessment of a target computing resource, such as a virtual machine or an instance of a virtual machine, include a scanning service that facilitates duplication of all or a portion of the target computing resource, and then performs the security assessment on the duplicate computing resource to avoid consuming processing time, processing power, and storage space of the target computing resource. A snapshot of the target computing resource, containing the data necessary to reproduce the portion to be assessed, is captured and used to implement the duplicate computing resource in newly allocated resources. The snapshot can be an image of a logical volume implementing the target computing resource. To reproduce a target virtual machine, the snapshot may include a configuration used to instantiate the target virtual machine; the scanning service may implement a duplicate virtual machine that is instantiated with the same configuration.

  • Patent number: 7312835
    Abstract: In a projection type display apparatus including a blue CRT display apparatus with low luminous efficiency and low luminous efficiency, the present invention seeks to improve contrast while suppressing the fall in brightness for red, green, and blue color as a whole. In the projection type display apparatus, the images of three colors outputted from three monochrome CRT display apparatuses 10R, 10G, 10B which respectively output monochromatic video signals of red, green, and blue color, are respectively projected on a screen unit 14 via a reflecting mirror 12 so as to synthesize a image of three colors and generate a color image. The brightness of the green CRT display apparatus which outputs the green image having the highest luminous efficiency is increased, while maintaining the brightness of the blue CRT display apparatus 10B. Further, a light absorption means for tinting to reduce the increased green brightness is provided to balance the whole brightness of red, green, and blue.

  • Patent number: 7295247
    Abstract: The present invention relates to adaptive time-shifting of audio frames (Fa) in encoded audio signal relative to video frames (Fv) in encoded video signal, which together form an audio/video message steam such that the corresponding decoded audio and video signals are aligned in time within the maximum degree of deviation. The invention accomplishes this alignment by determining a desired delay of the encoded audio signal for the decoded signals to meet deviation requirement The desired (Dd) delay is then converted into a frame delay number (nD), which is calculated as one of the two neighbouring integers to a ratio between the desired delay (Dd) and an interval (Ta) at which the audio frames (Fa) are received. A number of audio frames (Fa) equal to the frame delay number (nD) are alternately stored into respective read out from FIFO-buffers (309; 310) such that sufficiently delayed audio frames (Fa) are delivered to an audio decoding unit (313).

  • Patent number: 7283179
    Abstract: Disclosed herein is a video signal process circuit that includes a control circuit having a level detection circuit and a dynamic range switch circuit. In the control circuit and a microcomputer, an average luminance of an image displayed on a liquid crystal panel via a liquid crystal driver circuit is detected. When the average luminance is equal to or over a level YSmax, an upper limit of the dynamic range is expanded, so that a signal level of a composite video signal in which white blur can occur can be digitized to a digital signal without being limited by the upper limit gradation, reducing the white blur of the image to improve the quality of the image.
