Filed: 2002-05-31
Abstract: <P>PROBLEM TO BE SOLVED: To cut off a charging current for a battery pack by detecting a temperature rise in the battery pack, secure a space of the battery pack, and reduce the cost of the battery pack.  <P>SOLUTION: A thermosensor 14 incorporated in an IC 12 for circuit protection monitors a temperature in a battery pack. When the monitored temperature is elevated and reaches a prescribed temperature, a voltage signal corresponding linearly to the temperature rise is transmitted to a charge/discharge control circuit 21. The voltage signal is amplified and detected by a battery temperature detection amplifier 22. When the temperature reaches the prescribed battery temperature, the charge/discharge control circuit 21 of a charger 20 cuts off a charging current supplied to the battery pack 10.  <P>COPYRIGHT: (C)2003,JPO

Title: Image processing apparatus and its control method
Inventor: CHIKUMA SATOYUKI
IPC: G06T5/00
Filed: 2002-06-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image processing apparatus and method for realizing quantization of a multi-value color image having two color components or more through error spread processing to have the number of gradations less than the original number of gradations by using a lookup table having a small memory capacity.  <P>SOLUTION: When data have color components 0, 1 configuring received pixels, an error caused in the quantization processing is added to respective data positions and the result is given to an output setting section 2. Each of one-dimensional LUTs receives the data as addresses, quantizes the data in a way of having a narrower range than that of the original range of the data and outputs the result as g0, g1. An N-dimensional LUT receives the data g0, g1, regarded to have a correlation of the received data having the two color components, and outputs the final quantization result. Since the size of the memory space of the N-dimensional LUT is controlled by the g0, g1, this means that a narrower range taken by the g0, g1 is better. On the other hand, a wider range of the g0, g1 provides a quantization result more suitable for forming an image with high quality. Then the g0, g1 are decided so that the image quality is minimized within a permissible range.  <P>COPYRIGHT: (C)2004,JPO
