Abstract: An image processing circuit (1) of the present invention is provided with: a difference calculating device (100) for calculating difference value between a pixel level of a focused pixel and a pixel level of a referenced pixel; a first comparing device (100) for comparing the difference value with a first threshold; a counting device (110) for judging the referenced pixel that the difference value is less than or equal to a predetermined threshold to be a valid pixel, and counting the number of the valid pixels; a second comparing device (120) for comparing the number of the valid pixels with a second threshold; and a correcting device (12) for correcting the pixel level of the focused pixel, in case that the number of the valid pixels is more than or equal to a second threshold.

Abstract: Object To provide an image reproduction device for remotely reproducing image information from an AV device and facilitating remote operation of the AV device, Configuration An image reproduction device whereby image content and at least one menu image are acquired from an AV device via a communication network and reproduced on a monitor screen, whereby arrangement information concerning a plurality of menu selection branches in said menu image is stored for each menu image. The image reproduction device also identifies the in-reproduction menu image being reproduced, decides on one of the menu selection branches from among the plurality of selection branches in the in-reproduction menu image in accordance with the pointing information for the monitor image, and generates a menu selection signal in accordance with the first menu selection branch which is supplied to said AV device via said communication network.

Abstract: An information processor including a processing device for recording information on a recording medium or reproducing the information recorded on the recording medium, is provided with: an encrypting/decrypting device which is capable of an encrypting operation for encrypting the information to be recorded when the information is recorded on the recording medium and a decrypting operation for decrypting the information to be reproduced from the recording medium when the information is reproduced from the recording medium; the processing device which includes the two or more encrypting/decrypting devices; a control device which controls the encrypting/decrypting device so as to perform one of the encrypting operation and the decrypting operation; and a switching device which switches a transmission path of the information to the encrypting/decrypting device in response to one of the operations performed by the encrypting/decrypting device.
