Abstract: An imaging apparatus provided with a function of shooting a moving image and a still image, and capable of displaying an image to be captured on a display unit includes a first display control unit configured to display an confirmation image for checking an in-focus state on the display unit when a moving image is shot; and a second display control unit configured to change the confirmation image for checking an in-focus state displayed on the display unit by the first display control unit when a still image is shot during moving image shooting.

Abstract: A multi-function input switch comprises a rotary dial, and a joint portion connected to a side edge portion of a body frame including a display panel, wherein the rotary dial is arranged so that each of a circumferential surface portion and a circular plane portion is exposed from the body frame.

Abstract: A signal processing device of the present invention includes: an input unit which inputs an analog video signal; an A/D converter which converts the analog video signal to a digital video signal; a detecting unit which detects a level in a predetermined period of the digital video signal output from the A/D converter; a difference output unit which detects a difference between the level detected by the detecting unit and a desired value; a modulating unit which performs sigma-delta modulation on an output from the difference output unit; and a clamping unit which performs a clamping process on the analog video signal input by the input unit based on an output from the modulating unit and which outputs the clamped analog video signal to the A/D converter.

Abstract: An image display apparatus holds plural color conversion information patterns for performing a color conversion of pixels of drawing data. The image display apparatus is capable of selectively changing color conversion information for performing a color conversion of pixels of the drawing data within the same display screen. The image display apparatus combines a main picture with the drawing data converted based on the color conversion information.

Abstract: This invention prevents quality deterioration and positional shift of OSD when an image and the OSD are to be together displayed by LB display. An image processing apparatus having a function of superposing a second image on a first image includes a converter (103) which converts the length-to-breadth ratio of at least the first image, a first superposing unit (101) which superposes the second image on the first image before the length-to-breadth ratio is converted by the converter (103), and a second superposing unit (105) which superposes the second image on the first image after the length-to-breadth ratio is converted by the converter (103).

Abstract: This invention can reduce the circuit scale by synthesizing OSD data to be superposed on a picture of each resolution by using common OSD data. According to this invention, a video resolution converter converts an HD (High Definition) video signal into an SD (Standard Definition) video signal such as an NTSC or PAL video signal. A memory controller receives a sync signal identical to an SD picture obtained by frequency-dividing an HD video signal, and a sync signal based on an SD video signal, and reads out OSD data (4 bits per pixel) from the memory on the basis of these sync signals. The OSD data read out on the basis of the SD video signal is synthesized with the SD video signal by an SD_OSD_MIX unit, and then output. The OSD data read out on the basis of the SD sync signal synchronized with the HD is multiplied by an integer by an OSD resolution converter, synthesized with an HD video signal by an HD_OSD_MIX unit, and then output.

Abstract: It is made possible to maintain the security of one electronic device to which a plurality of other electronic devices are capable of being connected. To accomplish this, a notebook-type personal computer has an internal ROM storing ID information specific to this personal computer. The notebook-type personal computer is folded up and inserted into a docking station through an insertion port so as to be electrically connected to the docking station and rendered capable of executing processing that utilizes the resources of the docking station. The docking station has an internal non-volatile memory storing the IDs of notebook-type personal computers that are allowed to use the docking station. When a notebook-type personal computer is inserted into and connected with the docking station, use of the docking station is not allowed if the ID of this notebook-type personal computer has not been stored in the docking station.

Abstract: The invention aims at providing a notebook type personal computer having an improved portability. In order to achieve this object, a battery, case which houses a battery B for supplying a power to a personal computer body is detachably attached to a housing. The battery case has such a shape that it also serves as a palm rest used when a keyboard is operated. The battery case has a battery case body for housing the battery B, and an attaching/detaching portion connected to the battery case body and attached to and detached from the housing. The battery case body is connected to the attaching/detaching portion to be pivotal in a direction of thickness of the housing.

Abstract: An operating system is constructed, and optimized in a given environment, for use in an image processing system that includes a first electronic device capable of operating independently and having a standard input/output unit, and a second electronic device which, when the first electronic device has been connected thereto, extends the functionality of the first electronic device and is capable of being used instead of the standard input/output unit to perform operations. To accomplish this, a foldable notebook-type personal computer is folded up and inserted into a docking station through an insertion port so as to be electrically connected to the docking station. The notebook-type personal computer has a CPU for sensing the resources of the personal computer and the resources of the docking station and starting up the operating system upon selecting the optimum resources sensed.
