Abstract: A system and method for operating a mobile electronic device is disclosed. An intermittent reception is performed to reduce or minimize power consumption during a sleep mode while the mobile electronic device is communicating with at least one base station. At least a first voltage is provided on a chip-enable terminal of an LED driving circuit to cause an LED to blink after the intermittent reception.

Abstract: In a moving image encoding apparatus, an image signal is converted into a digital image signal by an A/D converter and is stored in frame memory 110. In addition, a movement vector detector 300 detects a movement of the output of the frame memory 110. In an orthogonal transformer 130, a difference signal between a present frame image which is stored in the frame memory 110 and a previous frame image which is stored in a variable delay frame memory 210 is supplied, in which the difference signal is converted by orthogonal transformation. The orthogonally transformed transformation signal is quantized into a linear or nonlinear discrete level on the basis of a step width of quantization from a step size controller 600 in a quantizer 140. Then, the quantized data is encoded into a variable length code in a variable length encoder 150. A movement vector detector 300 detects movement of the image by pattern matching processing between the present frame and the previous frame.

Abstract: An image signal encoding apparatus having a control means for detecting a degree of redundancy of an inputted image signal and for conducting frame skip control based on a frame skip number determination and a determined skip number, an encoding processing means for processing a frame signal indicated by a transmission from said control means by block units into which a screen is divided, quantizing this signal, and encoding and outputting this signal through the medium of a transmission buffer, and a step size control means for controlling the step size of the quantization, characterized in that the step size control means comprises a correction buffer amount calculation means, which calculates a correction buffer amount indicating an excess in the transmission buffer from the frame skip number and a previously supplied transmission speed, and a step size calculation means, which outputs a quantization step size which is smaller as the correction buffer amount indicates a larger excess of the transmission bu
