Disclosed is a method for controlling a cordless telephone device for use in a system that allows remote control of a home electric appliance. The method includes a first generation step of causing a first generation unit in a handset to encode audio input via a sound receiving unit in the handset to generate a first stream, and a first transmission step of transmitting the first stream to a base unit. The first generation step includes causing the first generation unit to generate instruction bit information and a first instruction stream when a first trigger indicating a request to start the remote control is given to the first generation unit. The first transmission step includes transmitting the instruction bit information and the first instruction stream to the base unit through a multiplexing scheme that is common to transmission of a first stream generated when the first trigger is not given.

A liquid crystal display includes a liquid crystal panel and a first to nth control substrates (n is an integer which is 2 or greater) which control the liquid crystal panel. When the first control substrate enters an operable status, the first control substrate transmits a readiness signal to the second control substrate which is at a next stage, and when the nth control substrate determines that the nth control substrate receives a readiness signal from a control substrate at a previous stage and is in an operable status, the nth control substrate transmits a readiness signal to the first control substrate, thereby being able to suppress a synchronization failure between the plurality of control substrates which are provided in a liquid crystal display.

A liquid crystal display device for carrying out a 3D display by a frame sequential method as well as a 2D display includes: a digital &#x3b3; correction section for changing an input gray level to a gamma characteristic corresponding to either the 2D display or the 3D display in accordance with a preset analog gamma value; an overdrive circuit for finding, in accordance with a parameter set according to the gamma characteristic thus corrected by the digital &#x3b3; correction section, an overdrive value corresponding to the input gray level; and an analog &#x3b3; correction section for finding a voltage value to be applied to liquid crystal by correcting the overdrive value found by the overdrive circuit. In the digital &#x3b3; correction section, an analog gamma value for the 3D display is set to be larger than an analog gamma value for the 2D display.

A gradation change detection circuit determines whether a gradation value has been changed from a previous frame. In at least one example embodiment, a first frame memory stores, when the gradation value is changed, a gradation value before change. A hold count calculation circuit determines a hold count indicating the number of frames inputted after the change of the gradation value. A second frame memory stores the determined hold counts. An emphasis conversion circuit performs a process of emphasizing a change in gradation value on a video signal, and makes a degree of emphasis smaller with a larger hold count. A liquid crystal panel is driven based on a video signal obtained by an overdrive circuit. By this, double optical responsivity occurring due to overdrive drive is prevented.

An object detection device is provided with a plurality of processor units each detecting an object included in an image. The object detection device generates divided images by dividing the image, taking into consideration both the processing load for detection of an object by each processor element and the transfer load for transfer of the divided images to the processor elements. Independently of each other, the processor elements detect an object in each of the divided images.

An image judgment device stores element characteristic information for each element of a characteristic part of a sample object and first and second positional information defining a position of each element, selects the first or the second positional information, and acquires image characteristic information for a partial image in an image frame considered as an element specified by the first positional information based on a first axis. The image judgment device also extracts image characteristic information for a partial image in an image frame considered as an element specified by the second positional information based on a second axis (which is acquired by rotating the first axis), specifies element characteristic information for an element corresponding to a position of the partial image, and judges whether the characteristic part appears in the image frame with use of the specified element characteristic information and the extracted image characteristic information.
