Abstract: PURPOSE: A circuit for automatically controlling a color temperature is to determine whether an input pixel signal is a moving image or a still image by comparing the input pixel signal with data stored in a memory. CONSTITUTION: An analog-to-digital conversion unit(10) converts an analog pixel signal into a digital signal. A moving/still image determination unit(20) determines whether the digital signal is a moving image or a still image by comparing the digital signal is with a data stored in a memory(30) to automatically control a color temperature. The moving/still image determination unit includes a frame data comparator, a counter circuit, a moving/still image detector and a color temperature controller. The frame data comparator compares the data and the frame data. If two data are equal to each other, the first logic data is outputted, and if not, the second logic data is outputted. The counter circuit counts the number of data different from previous frame by counting only the second logic data.

Abstract: PURPOSE: An accelerator pedal facilitates controlling the length of a cable connecting between an accelerator pedal and a throttle valve and also makes possible pushing the pedal to the end even when the cable is expanded. CONSTITUTION: An accelerator pedal comprises a rod(1), a spring(2) and a tensioning device. The tensioning device mounted for connecting between the spring(2) and a cable(54) has a flexible band(4) and a draw plate(6). When the accelerator pedal(51) is pushed, the flexible band(4) is drawn and then the cable(54) connected with the flexible band(4) is drawn, thereby actuating a throttle valve(53) and operating acceleration mode. If the cable(54) is expanded when the draw plate(6) is not engaged with the flexible band(4), the length of the cable(54) drawn by the draw plate(6) and the flexible band(4) keeps to be constant because the spring draws the cable(54). Thus, making the length of the cable(54) constant prevents the cable(54) from being drawn to the end when the accelerator pedal is pushed.
