  • Patent number: 8238737
    Abstract: A lens barrel that is capable of decreasing a barrel length under a retracted condition by simplifying a configuration. The lens barrel changes a focal length by moving first and second lens groups in an optical axis direction. A light-amount adjusting member is located between the first and second lens groups. First, second, third holding frames hold the first lens group, the second lens group, and the light-amount adjusting member, respectively. A cam mechanism moves the first, second, and third holding frames in the optical axis direction so that a part of the second lens group is inserted into the aperture of the light-amount adjusting member and concave and convex surfaces of the first and second lens groups are overlapped in the optical axis direction under a retracted condition. The aperture diameter of the light-amount adjusting member is enlarged when shifting to the retracted condition from a shooting condition.

  • Patent number: 8233001
    Abstract: A peripheral device acquires the processing load of a display apparatus to which the peripheral device is connected via an interface. In accordance with the processing load acquired, the peripheral device generates a data command for adjusting the load of processing for rendering display data. The display apparatus alters the display data based upon the data command, renders the display data after the alteration thereof and displays the rendered data. As a result, when the peripheral device instructs the display apparatus to subject the display data to rendering process, an increase in length of time it takes to obtain the result of rendering is reduced.

  • Patent number: 8229238
    Abstract: The invention provides an image encoding apparatus which can improve image quality of an output image while further reduce the amount of attribute. A determination unit determines an area including a character/line drawing as a foreground image area based on an input multi-valued image. A foreground image generator generates foreground image in binary representation so that a first encoder performs MMR encoding on the foreground image. A background image generator generates multi-valued background image data by replacing the value of a multi-valued pixel in a position of the character/line drawing in the foreground image area with a replacement value calculated from the pixel values in a position of the non-character/line drawing pixel. A second encoder performs JPEG encoding on the background image. A mask unit masks attribute for pixels within the foreground image area with a predetermined value to output the masked data to a third encoder.

  • Patent number: 8229243
    Abstract: A signal processing device, which is more practical for restoring signals, includes a signal processing unit for processing a signal. The processing unit produces restored data that approaches the original signal data before fluctuating (before blurring) by repeating the following processing: generating comparison data Io? from arbitrary signal data Io by using information data G regarding fluctuation factors that triggers signal fluctuation; comparing the comparison data Io? with original signal data Img? as an object to be processed thereafter; producing restored data Io+n by allocating difference data ? to the arbitrary signal data Io while using the information data G regarding fluctuation factors; and substituting the restored data Io+n for the arbitrary signal data Io thereafter.

  • Patent number: 8220936
    Abstract: An image projection apparatus in which a measuring unit measures a distance from the image projection apparatus to a projection surface. A generating unit generates a first operation image if the measured distance is less than a threshold value and generates a second operation image if the measured distance is not less than the threshold value. The first operation image is an image by which an operation can be input by pointing on the first operation image that is being projected with a body part of a user. The second operation image is an image by which an operation can be input by operating a cursor displayed in the second operation image that is being projected using a predetermined operating unit. A projecting unit projects an operation image generated by the generating unit onto the projection surface.

  • Patent number: 8225010
    Abstract: A data recording apparatus includes a connection unit which is capable of connecting, as a recording medium, a first recording medium having a predetermined function and a second recording medium that does not have the predetermined function. The data recording apparatus detects a connection status of the recording medium to the connection unit, controls a menu concerning setting of the predetermined function. If the detection unit detects that the first recording medium is connected to the connection unit, the data recording apparatus makes the menu operable. If the detection unit detects that the first recording medium is removed and then detects that the second recording medium is connected to the connection unit, the data recording apparatus makes the menu inoperable, and maintains the menu in the operable state during a period from removal of the first recording medium to connection of the second recording medium to the connection unit.
