Abstract: A peripheral control system enhances expandability in the operation of peripheral by enabling the customization and display of operation panels for each of the peripherals, regardless of whether any operation panel exists at the display device side. The peripheral control system is configured by connecting a TV and a recorder via an HDMI connection. The TV stores operation panel information that includes array information for arraying, on the screen, image data of the operation buttons that comprise the operation panel of the recorder. The recorder stores image data of the operation buttons, and sends, according to operation panel information obtained from the TV, the aforementioned stored image data of the operation buttons in association with the array information to the TV. The TV disposes and displays image data of the operation buttons sent from the recorder, at a position that is in accordance with the array information.

Abstract: A broadcast receiver which can receive broadcast by directly selecting a discretionary broadcast station from all the receivable broadcast stations. The broadcast receiver is provided with a broadcast receiving section having broadcast station searching means for searching a carrier frequency of the receivable broadcast station. The receivable carrier frequencies searched by the broadcast station searching means are displayed as a list of broadcast station information on a display section, a specification from the list of broadcast station information displayed on the display section is accepted by operation of an operating section, and broadcast of the carrier frequency corresponding to the accepted specification is permitted to be received by the broadcast receiving section.

Abstract: Conventionally, there have been a problem that when an imaging device performs aberration correction by itself, the imaging device has to have high processing ability and a large storage capacity and a problem that since the object subjected to aberration correction is image data read from an analog film by means of a scanner or the like, a region on an analog film from which the gray scale is lost is corrected as the gray scale is lost. To solve the problems, the present invention provides an imaging device in which the image captured by a digital imaging device and information for aberration correction embedded in the image as tag data of the Exif format are transmitted to an image reproducing device and aberration correction is performed in the image reproducing device.

Abstract: A character code storage device stores character codes together with display permission information (display levels) attached to every character code. A font data storage device stores font data together with display level values attached to every dot constituting a font. A dot-display-value synthesizer synthesizes these two data and controls dot-display for representing a character according to two kinds of information--display permission information and display level values. The display permission information from a display-permission-value register is reflected at every display level value of dots constituting a font corresponding to the character. When each dot is read from a display circuit, its display level value is also read out and transferred to a display control unit. The transferred dot is compared with a display-permission-level value stored. Dot data which does not meet the condition will not be sent to the display circuit. Consequently, this dot is masked.
