Filed: 1989-02-15
Abstract: PURPOSE:To easily detect the events in response to the operation of each system by deciding a display system based on the emerging frequency of a message. CONSTITUTION:At the system start, the identification information at every message recorded on an external memory 5 such as a magnetic disk and the corresponding information on the number of times of the message output are fetched into a main storage 2 to produce a table 3. When an output request is received for a message, the information on the relevant message is searched out of the table 3 based on the message identification information 31. Then the number of times of the message emerging is updated. Thus a new message emerging frequency is obtained, and a display system is decided based on the message emerging frequency. The message is outputted to a message display device 7 or the output of the message is suppressed. Thus it is possible to output a message having a low emerging frequency after emphasizing it and to easily detect a peculiar message. Then a user can easily detect an important message.

Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To improve the performance and efficiency of a device by improving a fact that a memory with a high capacity is required to store dark frames and a scanning time of an image sensor is very long in the case of correcting a black pattern due to a dark current. SOLUTION: An electronic image pickup device is provided, where a charge moving type image sensor 18 corrects a black pattern due to a dark current. The image sensor 18 acquires a reference dark frame in the dark and a dark frame pixel value. An exposure section adjusts an exposure time of a pickup light to provide corresponding exposure to pluralities of image frames. Thus, the image sensor 18 generates pluralities of corresponding image frames each having a frame pixel value. Then a processor 38 obtains a reference coefficient from the dark frame pixel value, applies it to the frame pixel value of pluralities of the image frames to obtain the corrected image frame pixel values where the black pattern is corrected.  Since the one reference dark frame exposure is employed for the correction of the exposure of lots of the image frames, the performance and the efficiency of the device are enhanced.
