20080246544Offset adjustment device, semiconductor device, display device, offset adjustment method, noise detection device, and noise detection method - In one embodiment of the present invention, an operational amplifier circuit, a switching element is closed and a switching element is opened. A latch circuit DL latches an output voltage of an operational amplifier and supplies a Q output corresponding to the output voltage. A control circuit supplies an offset adjustment signal to an offset adjustment input terminal OR of the operational amplifier, thereby adjusting an offset of the output voltage. The latch circuit DL latches again the output voltage thus adjusted and minutely adjusts the offset adjustment signal so as to adjust the remaining offset. Weighting is carried out in accordance with how many times latching has been carried out, and the offset of the output voltage of the operational amplifier is quantized, thereby obtaining a binary logical signal and storing the signal in the control circuit. This realizes a small-scale offset adjustment device which is capable of absorbing offset variations and which does not require a frequent refreshment process.10-09-2008

20100067887IMAGE CAPTURE DEVICE WITH AUTOMATIC FOCUSING FUNCTION - In a digital camera, a focus lens is moved at a low speed between a timing at which a shutter key is half pressed and a timing at which the shutter key is fully pressed to detect a focused position. When the shutter key is fully pressed by a user before the focus lens reaches a focused position, the focus lens is moved at a higher speed than that of a case in which the shutter key is half pressed, and a focused position is detected. Thereby, even when the shutter key is fully pressed by a user before the focus lens reaches the focused position, the digital camera can realize focusing with less delay in capturing.03-18-2010
