According to the video information adjusting apparatus, the image information which is transmitted out can be adjusted at each receiving side.
SUMMARY OF THE INVENTION The present invention performs the adjustment of illuminance information and/or image resolution by using an improved type CCD (solid-state imaging device) described in a previous patent application filed by the present inventor. The improved type CCD means that an improvement is made in the amount of charge transfer in a CCD.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Referring now to FIG. 5, there is shown therein a diagram showing the configuration of a video information adjusting apparatus according to a first embodiment of the present invention. The video information adjusting apparatus shown here is the type that can adjust illuminance information between terminals. More specifically, an input part 502 of a terminal 501 is a camera having an illuminance information acquiring part 511 and an illuminance information adjusting part 512. The illuminance information acquiring part 511 comprises a CCD of improved type and is responsible for image information collection. The illuminance information adjusting part 512 is a circuit which performs brightness adjustments on two kinds of information, high illuminance information and standard illuminance information, acquired by the improved type CCD, and which supplies image information, corresponding to part of the brightness-adjusted, expanded image information, and information concerning imaging conditions to an identifier appending part 503. An output part 503 allows the connection of a viewing apparatus (such as a display), an audio output apparatus (such as a speaker, amplifier, etc.), a recording apparatus (such as a VTR, hard disk, optical disk, etc.), and a printer or the like. A transmitting part 504 is a transmission device compatible with a LAN, CATV, modem, digital PBX, or the like. A terminal control part 505 is a control unit responsible for the overall control of these parts.
Embodiment 2 Referring to FIG. 7, there is shown therein a diagram showing the configuration of a video information adjusting apparatus according to a second embodiment of the present invention. The apparatus shown here is the type that controls the illuminance information centrally in one location. First, the configuration of a terminal 701 will be described. An input part 702 of the terminal 701 is a camera having an illuminance information acquiring part 711. The illuminance information acquiring part 711 comprises a CCD of improved type and is responsible for image information collection. An output part 703 allows the connection of a viewing apparatus (such as a display), an audio output apparatus (such as a speaker, amplifier, etc.), a recording apparatus (such as a VTR, hard disk, optical disk, etc.), and a printer or the like. A transmitting part 704 is a transmission device compatible with a LAN, CATV, modem, digital PBX, or the like. A terminal control part 705 is a control unit responsible for the overall control of these parts.
Embodiment 3 Referring to FIG. 10, there is shown therein a diagram showing the configuration of a video information adjusting apparatus according to a third embodiment of the present invention. The video information adjusting apparatus shown here is the type that can adjust resolution between terminals. More specifically, an input part 1002 of a terminal 1001 is a camera having a resolution information acquiring part 1011 and a resolution information adjusting part 1012. The resolution information acquiring part 1011 comprises a CCD of improved type and outputs a PD signal of even-numbered lines and a PD signal of odd-numbered lines separately and independently of each other on a field-by-field basis. The resolution information adjusting part 1012 is a device for generating image information at prescribed resolution by using the PD signals of even-numbered lines and odd-numbered lines supplied from the resolution information acquiring part 1011. An output part 1003 allows the connection of a display apparatus (such as a display), an audio output apparatus (such as a speaker, amplifier, etc.), a recording apparatus (such as a VTR, hard disk, optical disk, etc.), and a printer or the like. A transmitting part 1004 is a transmission device compatible with a LAN, CATV, modem, digital PBX, or the like. A terminal control part 1005 is a control unit responsible for the overall control of these parts. The input part 1002 also allows the connection of an input device such as a keyboard, mouse, digitizer, touch panel, light pen, microphone, etc.
Embodiment 4 Referring to FIG. 11, there is shown therein a diagram showing the configuration of a video information adjusting apparatus according to a fourth embodiment of the present invention. The video information adjusting apparatus shown here is the type that controls resolution information centrally in one location. First, the configuration of a terminal 1101 will be described. An input part 1102 is a camera having a resolution information acquiring part 1011. The resolution information acquiring part 1011 comprises a CCD of improved type and outputs a PD signal of even-numbered lines and a PD signal of odd-numbered lines separately and independently of each other. An output part 1103 allows the connection of a viewing apparatus (such as a display), an audio output apparatus (such as a speaker, amplifier, etc.), a recording apparatus (such as a VTR, hard disk, optical disk, etc.), and a printer or the like. A transmitting part 1104 is a transmission device compatible with a LAN, CATV, modem, digital PBX, or the like. A terminal control part 1105 is a control unit responsible for the overall control of these parts.
Embodiment 5 FIGS. 12 and 13 are diagrams showing the configuration of an video information adjusting apparatus according to a fifth embodiment of the present invention. The video information adjusting apparatus shown here monitors the working condition of a terminal user, and based on the working condition, automatically adjusts the previously described illuminance information adjusting part and resolution information adjusting part. The video information adjusting apparatus is shown in two types: one is the terminal apparatus shown in FIG. 12 and the other is the terminal support apparatus shown in FIG. 13. A working condition managing part 1208 (or 1308) for managing the working condition of the user is controlled by a terminal control part 1205 (or terminal support control part 1307). The working condition of the user is stored in a working condition storing part 1209 (or 1309) for management.
