Patent number: 7542968Abstract: Cache hit ratio is improved in a cache apparatus that reads and caches contents from a large-scale database. The cache apparatus includes a cache section for recording a plurality of sets. Each set includes an attribute ID, an extractor for extracting the attribute ID from an object ID, and attribute data identified by the attribute ID. The cache apparatus receives an object ID and extracts an attribute ID from the object ID using an extractor recorded in the cache section.

Patent number: 6002537Abstract: A rotary head type reproducing apparatus capable of displaying each data code indicative of date, time and frame number, without interruption even during reproduction from a recording track on which a recording is made with such data code absent. In the apparatus, a recording track having a data code signal recording area in which a search marker is recorded is scanned by a rotary head, and when the search marker is reproduced and outputted, the search marker is demodulated by a search marker demodulating circuit and, simultaneously, the output of a data interpolating circuit is selected at the input of a switch. Each time a variation point of an SWP (head switching pulse) is detected by an SWP detecting circuit, the data interpolating circuit increments the respective count values of a frame counter, a time counter and a date counter decoded from a data code, on the basis of a data code obtained immediately before the demodulation of the search marker, and outputs the result to a system control circuit.Type: GrantFiled: March 24, 1997Date of Patent: December 14, 1999Assignee: Canon Kabushiki KaishaInventor: Keiji Satoh

Patent number: 5742400Abstract: An image processing apparatus can improve positional accuracy by effecting median filtering processing while ensuring real-time operations by reducing the amount of data processing by software. In this image processing apparatus, when a counter has counted up to a predetermined number, or when the counter's value is increased by a predetermined number after the counter has counted up to the predetermined number, a filter circuit control section activates a filter circuit. As a result, the filter circuit performs median filter processing for multi-gradation image data stored in an FIFO storage section. The image processing apparatus is suitable for use in measuring the position, shape, size, etc. of an object from multi-gradation image data obtained as a result of photographing the object with a camera or the like.Type: GrantFiled: April 15, 1996Date of Patent: April 21, 1998Assignee: Fujitsu LimitedInventor: Keiji Satoh
