  • Patent number: 10725109
    Abstract: A battery monitoring circuit for a portable device driven by a secondary battery that supplies an electric current via a wiring pattern formed on a substrate. The battery monitoring circuit includes: a current measuring circuit that measures a current value of a current that flows in the wiring pattern by monitoring an amount of voltage drop that occurs in a specific section of the wiring pattern; a converter that converts the current value into a digital measured current value; a first storage part that stores data for compensating a variation in a resistance value of the wiring pattern depending on an individual particularity of the substrate; and a calculating part configured to correct the digital measured current value by using the data to calculate a corrected current value and to calculate a remaining capacity or to monitor a state of the secondary battery based on the corrected current value.

  • Publication number: 20050212943
    Abstract: The digital camera has an LCD and a print button and can set image capturing modes such as a single frame shooting mode and a continuous shooting mode. In the case where the print button is depressed in a state where the digital camera is set in the single frame shooting mode, after making an error check, the digital camera immediately shifts to a state where a print mode is set. In the print mode, a print setting screen in which settings of a print order can be made on an image recorded on a memory card is displayed on the LCD. As a result, settings of the print order can be made promptly.

  • Publication number: 20050212915
    Abstract: The present invention provides a digital camera capable of optimizing a timing of switching a display screen to a print setting screen including an image on which print settings are to be made. In a process of protecting or formatting a captured image in a playback mode, a process of recording a captured image in an image capturing mode, and the like, a request of a file access (writing) to a memory card is generated. In response to the request or the like, a state where a file in the memory card is protected from other accesses is set, and writing of the file starts. After that, writing of the file is completed, and various accesses to the file in the memory card are permitted. That is, during a file access (writing), in response to depression of a print button, an operation of reading an image file in the memory card and switching to a print mode is inhibited.
