Abstract: In a television, which can be connected to a portable information terminal, it is possible to display video based on the data of a multimedia file stored on a storage medium even in cases where there is no built-in decoder. In cases where a TV itself does not possess a decoder which can decode the data of a multimedia file selected by the user from the multimedia files stored on the USB memory, the CPU of the TV transmits to a smartphone the data of the selected multimedia file and a decoding request command to request that the data be decoded, thus receiving a video signal and/or an audio signal obtained by various types of decoders of the smartphone. Consequently, the CPU of the TV can output video and/or audio to a display unit and a speaker on the basis of the data of the selected multimedia file.

Abstract: A TV receiver as an electronic device is connected to an adjustment device by an exclusive cable of two transmission lines connected to an HDMI connection terminal. In adjustment mode, a main microcomputer of the TV receiver sends a signal to the adjustment device through a transmission line including an HPD line with an HPD port serving as an output port for the signal, and receives a signal from the adjustment device through a transmission line including a +5V line with a +5V port serving as an input port for the signal. Thus, the microcomputer can perform adjustment processes by receiving product information and various set values from the adjustment device to store them in a memory, and by sending the stored various values to the adjustment device, without providing a UART port, making it possible to reduce manufacturing cost.

Abstract: When a target image with an aspect ratio of 4:3 is displayed on the screen A of the PDP26 with an aspect ratio of 16:9, the rectangular black images on the left and right of the target image are not solid black. Instead, the luminance of the rectangular black images is lowered stepwise as it becomes more distant from the boundary of the target image, and finally reduced to substantially zero, or to a black image at a position away from the boundary to some extent. This prevents the luminance from sharply falling from the boundary and edge from causing due to the addition of the rectangular black image, thereby preventing burning on a part of the screen A corresponding to the position of the boundary.

Abstract: The present invention discloses an HDTV, and a method for controlling adjustment of the HDTV, which make it possible to set control information of the HDTV easily at low cost without unpacking the TV set. Adjustment data is included in an INFO frame, transmitted from an external device, and written into a register of an HDMI receiver 14 through a video signal input terminal 13. Further, a microcomputer 15 reads the adjustment data and controls the adjustment of the HDTV 11 based on contents of the data.

Abstract: When showing a picture without trimming it while a video signal stored in a frame memory 26 has an aspect ratio different from that of a screen of a plasma display panel 29, with respect to video signals E2a and E2b in areas bordering on blank zones E1 and E3 containing no picture appearing in upper and lower or right and left ends of the screen of the plasma display panel 29, a video signal processor 23 reduces a luminance difference by lowering levels of overshoots 30a and 30b and undershoots 30c and 30d accompanying sharpness processing applied to cope with blurring in edge portions caused by bilinear interpolation, thereby suppresses burn-in of the video signals E2a and E2b in said areas bordering on the blank zones on the plasma display panel 29.

Abstract: According to the invention, performing torn curb correction processing by referring to plural correction tables 113a to 113c for plural display areas A, B, C, D, E, and P makes it possible to obtain an output image meeting user's requirements. Particularly, since tone curve correction processing can be performed by referring to different correction tables selected from the correction tables 113a to 113c for a main screen to be displayed in the display areas A, B, C, D, and E and for a subscreen to be displayed in a sub-display area P, discomfort to a viewer attributable to a difference in brightness between the main screen and the subscreen can be prevented.

Abstract: According to the present invention, with an HDMI terminal 10a and a composite terminal 10b, a digital decoder 10c outputs an image signal inputted through the HDMI terminal 10a to the subsequent stage through a scaler 10e, an analog decoder 10d, under control by a microcomputer 10i, extracts Closed Caption from a composite signal and outputs it to the microcomputer 10i, and an OSD superimposing section 10f, under control by the microcomputer 10i, on-screen-displays the Closed Caption on the image signal.

Abstract: Disclosed is a television adjustment system wherein component adjustment values (second adjustment values) for adjusting the white balance of an image based on the component video signal (a second video signal) are stored in an EEPROM (a nonvolatile memory). When the component video signal is inputted and an image based on the inputted component video signal is to be displayed, the component video signal is adjusted by amounts dependent on the component adjustment values so that an image which has been subjected to white balance adjustment intended for an image based on the component video signal is displayed. The difference in white balance observed between images based on the composite and the component video signals inputted to a television can be reduced.

Abstract: An objective is to speed up halftone processing and color conversion processing while securing the good rubfastness of colored ink dots formed on a printed image. According to the invention, performing torn curb correction processing by referring to plural correction tables 113a to 113c for plural display areas A, B, C, D, E, and P makes it possible to obtain an output image meeting user's requirements. Particularly, since tone curve correction processing can be performed by referring to different correction tables selected from the correction tables 113a to 113c for a main screen to be displayed in the display areas A, B, C, D, and E and for a subscreen to be displayed in a sub-display area P, discomfort to a viewer attributable to a difference in brightness between the main screen and the subscreen can be prevented.
