An address for a character generator ROM is composed of an upper readout address portion which is a character code loaded from a text memory for storing texts edited by a microcomputer and a lower readout address portion which is a value of a counter. Output data from the character generator ROM accessed by the above addresses are loaded in parallel by left-shift and right-shift registers. The output data is serialized by the left-shift register to form character pattern data, which in turn is superimposed on a video picture signal to be outputted to a VTR portion. In response to a self-image picture taking mode signal, one output is selected by a selector from the output of the left-shift register and the output of the right-shift register. The thus selected output is superimposed over the video picture signal to be delivered to a monitor screen driver circuit. The monitor screen driver circuit horizontally inverts the scanning direction in order to display a mirror-image of the picture on the monitor screen when the video camera is operated in the self-image picture taking state. |

DETAILED DESCRIPTION In view of the above problems of the prior art video camera, the present invention is to allow proper character display on the monitor screen without characters horizontally or vertically inverted.
It is therefore an object of the present invention to provide a monitor screen-integrated video camera (to be referred to as a video camera hereinafter) which includes a camera portion having a camera lens for picking up a picture of objects, a monitor portion having a monitor screen such as of LCD (liquid crystal display), etc.
, for displaying a video picture taken by the camera portion or a video picture reproduced from a video tape and a joint structure for rotatably jointing the camera portion with the monitor portion, and which can be used both for normal picture taking in which the lens face of the camera lens is opposed to the face of the monitor screen and for self-image picture taking in which the lens face of the camera lens and the face of the monitor screen are oriented in the same direction.
Further, it is another object of the present invention to provide a video camera having the above configuration, which has a function allowing the scanning direction on the monitor screen to be inverted in order to horizontally invert the video picture that is taken by the camera portion in the self-image picture taking state to thereby display a mirror-image of the taken picture on the monitor screen.
(Here, this function will be refereed to as a mirror-image display function.
) In order to achieve the above object, the present 10 invention provides a superimposition controlling circuit which generally allows character display such as a date, operation indication and caution indication relating to the operation state of the video camera to be displayed on the monitor screen of the video camera and which generally allows character display such as a date, time and the like to be recorded on a video tape, and which, when the monitor screen is scanned in an opposite direction because of the aforementioned mirror-image display function, makes it possible to display properly readable character patterns on the monitor screen by horizontally or vertically inverting the text display signals of the characters to be superimposed on the monitor screen
