Abstract:
PROBLEM TO BE SOLVED: To properly grasp information on an exchangeable lens used for each photographed image without causing a trouble at a user side. SOLUTION: An image signal that forms the image of an object captured through the exchangeable lens 100 and an image element 201 with timing in response to the instruction of the user is processed by a signal processing section 202 to be image data for recording. The lens information of the exchangeable lens 100 is read out and obtained by a control section 210 from a lens information memory 101 mounted in a cubicle of the exchangeable lens 100. An image file containing the image data created by the signal processing section 202 and the lens information obtained by the control section 210 is created by a record reproducing section 204, and the image file is recorded in a recording medium 250 by a record reproducing section 204.

Abstract:
PROBLEM TO BE SOLVED: To reduce software processing by decreasing a circuit scale when the number of pixels is converted. SOLUTION: A memory controller 5 converts the number of pixels of a photographed image of a OCD 2, and the image is JPEG-compressed, captured into a DRAM 9, and stored on an external storage medium 11. Then JPEG data reproduced from the external storage medium 11 are stored in the DRAM 9, JPEG-decompressed, and displayed on an LCD 8 through a memory controller 5 and a buffer memory 6. When the photographed image is captured, the memory controller 5 performs conversion of the number of horizontal pixels by an arithmetic circuit in a horizontal pixel number conversion section 51 and performs conversion of the number of vertical lines by software of a CPU 12. The CCD 2 generates an imaging output having lines thinned out in an EtoE mode for a monitor. Switching of the mode of the CCD 2 is used for the pixel number conversion. When confirmation reproduction or reproduction are performed, the number of lines is converted by thinning out readout addresses of the DRAM 9. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To search a desired image more rapidly and reliably. SOLUTION: A keyword searching section 121 searches a keyword set on image data from a recording medium based on a keyword, and an imaging information searching section 122 searches imaging information set on the image data from the recording medium based on imaging information. A section 114 for searching image set with similar information searches similar image data, i.e. image data having high correlation with searched keyword or imaging information, based on the keyword or imaging information searched at the keyword searching section 121 or the imaging information searching section 122. A keyword extracting section 115 extracts a keyword from similar image data, and a keyword setting section 116 sets the extracted keyword for the image data searched at the keyword searching section 121 or the imaging information searching section 122 so that a desired image can be searched more quickly and surely. The invention is applicable to an image management device. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To enable easy and flexible setting of processing different for each content to be managed. SOLUTION: An entry (i) of a content management file is composed of a pointer to a "content (i)" which is information indicating the position of the content (i) on a recording medium 2, attribute information including recording date, changing date or information regarding protection and the like, thumbnail of the content (i), text information, reproduction starting script 82 which activates before reproduction of the content (i) when the reproduction of the content (i) is instructed in response to an operation input from a user, which is accepted via an operating part, and a reproduction terminating script 82 which activates when the reproduction of the content (i) is terminated. The present invention can be applied to an imaging apparatus for recording image data of an object imaged on a recording medium. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To simply and surely update firmware in a simple constitution in a temporary firmware update applied to a portable type video camera using, for example, DVD. SOLUTION: This electronic device is so constituted as to transfer the firmware stored in a nonvolatile memory 12 to an execution memory 13 and execute it by starting of a power supply. This device temporarily updates the firmware by rewriting the firmware recorded in the execution memory 13. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To easily manage a bus by newly retrieving a node with first and second storage means, acquiring a necessary channel from the retrieved node by a node by which synchronous communication is performed within specified time and acquiring a necessary channel by nodes except the one by which the synchronous communication is performed after the specified time elapses. SOLUTION: An instruction to read the contents of a used channel register REG1 in a bus management node 11 is transmitted and if an idle channel exists, a writing instruction corresponding to a channel number which is desired to be used is transmitted by the node 12 to perform synchronous communication. Next, an instruction to read the contents of a bus capacitance register REG2 for the bus management node 11 is transmitted, its value is compared with a bus capacitance to be newly used in the synchronous communication, when its value is more or equal to the bus capacitance to be newly used, a writing instruction to define a value obtained by subtracting the bus capacitance to be newly used from the value as a new value of the bus capacitance register REG2 is transmitted and the synchronous communication is started.
Abstract:
PURPOSE:To accurately and automatically discriminate the scanning system of a recorded signal in the video recording and reproducing device such as a video tape recorder. CONSTITUTION:A horizontal synchronizing signal outputted from a video demodulation circuit 5 is fed to a period measurement section 6, in which the period is measured. An output of the period measurement section 6 is fed to a comparator section 7 comprising comparators 7a, 7b. A 1st reference signal from a terminal 8 is fed to the comparator 7a and a 2nd reference signal is fed from a terminal 9 to the comparator 7b respectively. An output from the period measurement section 6 and a reference signal compare in the comparators 7a, 7b. Depending on the result of comparison, the comparator section 7 sends a switching signal to a servo control section 10.

Abstract:
PURPOSE:To count the accurate wave number of an input sine wave, signal even though the noises or drifts may be superposed on the sine wave signal by setting en output signal at a low or high level when the difference between the maximum and minimum values of the input sine wave signal exceeds 8 prescribed level. CONSTITUTION:A sine wave signal (a) outputted from a Hall device 2 is inputted to an input terminal T0 end then to an input terminal T1 of a microcomputer 7 via an amplifier 6. Then the signal (a) undergoes the A/D conversion through an A/D converter 70 and is inputted to an extreme value detecting means 71 and a level control means 72. The means 71 detects the maximum or minimum value of the signal (a), and the means 72 sets a pulse train signal (b) at a low or high level when the difference between the detected maximum or minimum value and the level of the signal (a) exceeds a prescribed level.
Abstract:
PURPOSE:To reduce the power consumption by supplying no electric power to an image pickup system in a stand-by state by turning ON a recording switch after turning ON a main switch. CONSTITUTION:When a user turns ON the main switch 11A at a point t1 of the time, a power source supplies electric power S1, but only a control circuit 12 is placed in operation in this state and the electric power is supplied to none of other circuit parts such as the stop device of an optical system 16, an automatic focusing device, a camera signal processing circuit 18, a VTR signal processing circuit 19, a recording amplifier circuit 21, a system control circuit 13, and a servo circuit 14. The user, however, can see a subject image to be picked up through an optical viewfinder 15 even in this stand-by state corresponding to an angle of actual photography. Then the recording switch 11B is turned ON at a point t2 of the time and all the circuit parts following the circuit 12 are supplied with the electric power to start recording operation.
