Patent ID: 8294828

Claim:
A television apparatus, comprising: an image and tone control device, including a video processing circuit that receives video signals composed of image signals and audio signals, and performs predetermined signal processing on the image signal, and an audio processing circuit that performs predetermined signal processing on the audio signal; a display panel that displays an image based on the image signal processed by the video processing circuit; a speaker that outputs an audio based on the audio signal processed by the audio processing circuit; a microcomputer that issues signal processing instructions to the image and tone control device based on a user's operation; and a memory Integrated Circuit (IC) that stores programs and tables to be executed by the microcomputer, the memory IC, including: an image and tone characteristics table that serves to collectively store, for a television apparatus of each manufacturer of a plurality of different manufacturers, image control parameters of contrast, tint, brightness, sharpness, gamma value, and color temperature with which the video processing circuit performs signal processing and tone control parameters with which the audio processing circuit performs signal processing, for approximating the image and tone characteristics from the different manufacturers; and an image and tone control program configured so that when a user selects a manufacturer of the plurality of different manufacturers to which a user wants to approximate the image and tone, the microcomputer refers to the image and tone characteristics table, refers to signal processing parameters used for approximation to the selected manufacturer-specific image and tone of the television apparatus, and issues image and tone control instructions to the video processing circuit and the audio processing circuit, wherein the issuing of image and tone control instructions to the video processing circuit and the audio processing circuit is performed without the user individually adjusting the image control parameters and the tone control parameters.
