Automatic gain control circuit

A first signal path including a first LNA 3 and a second signal path including an antenna damping circuit 4 and a second LNA 5 are connected in parallel, and switching into either the first signal path or the second signal path is carried out to control a gain of a received signal. When a level of the received signal is higher than a first threshold, it is once attenuated by the antenna damping circuit 4 and is then amplified by a necessary quantity through the second LNA 5. Thus, the gain of the received signal is controlled in a total of the attenuation and the amplification. Consequently, a level of a signal to be input to the second LNA 5 is reduced to cause a distortion of the signal in the amplification with difficulty.

Image processing apparatus and method of controlling the same

This invention enables, for example, reduction of motion blur in a hold-type display device and reduce flicker in an impulse-type display device by a simple process. For this purpose, an LPF filters a frame of input image data (A[i]) to generate low-frequency image data (L). A subtractor and an adder generate high-frequency image data (SH). Another adder adds the low-frequency image data (L) from a delay circuit to subsequent low-frequency image data. A divider halves the sum to generate low-frequency averaged image data (SL). A switch alternately outputs the high-frequency image data (SH) and the low-frequency image data (SL) every time a frame of image data is input. As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.
