Abstract: Provided is a zoom lens including a focus lens portion, a zoom portion, an aperture stop, and a relay portion that does not move for zooming but comprises a negative fourth-first unit, a fourth-second unit interchangeable for an optical path, a positive fourth-third unit, and a fourth-fourth unit inserteable for the optical path for shifting a focal length range of an entire system to a long focal length side after removing the fourth-second unit from the optical path, and a distance on an optical axis between the aperture stop and a last lens surface of the fourth-fourth unit in a state of inserting the fourth-fourth unit in the optical path, a distance on the optical axis between a first lens surface and the last lens surface of the fourth-fourth unit, and an aperture diameter in an opened state of the aperture stop satisfy a predetermined conditions.

Abstract: An image pickup apparatus comprising: a lens apparatus having: an image pickup optical system including a focus lens unit and a zoom lens unit; a zoom state detector; and a controller; a camera apparatus having: a light receiving unit; and an image display unit; an AF frame operation unit; and a distance measuring unit installed with a parallax with respect to an optical axis of the image pickup optical system, in which the controller is configured to: select, from among measured distances obtained by the distance measuring unit, a measured distance obtained in an angle of field of the AF frame, based on a position of the zoom lens unit detected by the zoom state detector and a position of the AF frame set in the display; and perform the focusing by driving the focus lens unit based on the selected measured distance.

Abstract: A display device includes: a monitor and receiving set having a video signal receiving section, a display section, an image quality control section, a first control signal transceiver, and a first control section; and a control and transmission set having a television broadcast receiving section, a video signal input section, a video signal transmitting section, a second control signal transceiver, a key input section, and a second control section. The Power consumption of a first radio transmission path formed by the video signal transmitting section and the video signal receiving section is larger than that of a second radio transmission path formed by the first and second control signal transceivers. A control signal for a user interface is communicated by the first and second control signal transceivers. Only the second radio transmission path of the first and second radio transmission paths is communicable in a standby state.

Abstract: A main menu is displayed by operating a menu key, and "C. MENU" is selected to display a customized menu set screen, and "SELECT ITEM" is selected to display "SELECT ITEM" screen (S001-S003). Then, a sub-operation item, for example, "VIDEO MODE" is selected from a list for sub-operation items displayed on the screen by using a selection key and, further, a display order thereof is are selected. When there are plurality number of items desired by the user, selecting operation is conducted by repeating steps S004, S005 and S006 and, when selection for the items is completed, "SELECT ITEM" screen is ended (S007). The customized menu can be thus constructed by predetermined sub-operation items.

Abstract: When a program-scanning is executed, the scanning picture is displayed such that contents of the image can be reliably recognized while an image of the program that has been displayed so far is displayed on the picture screen. A television receiver has a function to display a sub-picture smaller than a main picture. When the television receiver enters a program-scanning mode, a broadcasting program or an image source whose image has been displayed on the whole picture screen of a display or whose image has been displayed as a main picture (41) is displayed on a sub-picture screen (42). Image of a plurality of broadcasting programs which result from changing the tuning state in the tuner are sequentially displayed on the main picture (41), thereby executing the program-scanning.
