Abstract

A solid state television camera with a pattern generator is disclosed for permitting a character display in a portion of a television picture. Both a solid state image sensor and a pattern generator are driven by the same synchronizing signal generator. A pattern signal generated by the character generator is superimposed upon or replaces a portion of the picked up image signal so that the pattern can be inserted into the picture.

Claims

1. A television camera comprising:

a solid state image sensor means for generating a picked-up signal corresponding to an object in order to produce a picture of the object;

a pattern generator means for generating a pattern signal to be inserted in the picked-up signal for the picture;

a synchronizing signal generator means for creating horizontal and vertical driving pulses for said solid state image sensor means and said pattern generator means;

said solid state image sensor means including means for mixing said pattern signal with the picked-up signal to create a mixed signal from the image sensor means;

an encoder means for converting the mixed signal into a desired video signal;

said image sensor means comprising a charge coupled device including a photo sensitive array and a horizontal read out shift register; and

said pattern signal being supplied to said horizontal read out shift register.

2. A television camera comprising:

a solid state image sensor means for generating a picked-up signal corresponding to an object in order to produce a picture of the object;

a pattern generator means for generating a pattern signal to be inserted in the picked-up signal for the picture;

a synchronizing signal generator means for creating horizontal and vertical driving pulses for said solid state image sensor means and said pattern generator means;

said solid state image sensor means including means for mixing said pattern signal with the picked-up signal to create a mixed signal from the image sensor means;

an encoder means for converting the mixed signal into a desired video signal;

said image sensor means comprising a charge coupled device including a photo sensitive array and a horizontal read out shift register; and

a buffer memory means for storing the pattern signal to be transferred to said horizontal shift register.

3. A television camera comprising:

a solid state image sensor means for generating a picked-up signal corresponding to an object in order to produce a picture of the object;

a pattern generator means for generating a pattern signal to be inserted in the picked-up signal for the picture;

a synchronizing signal generator means for creating horizontal and vertical driving pulses for said solid state image sensor means and said pattern generator means;

said solid state image sensor means including means for mixing said pattern signal with the picked-up signal to create a mixed signal from the image sensor means;

an encoder means for converting the mixed signal into a desired video signal;

said image sensor means comprising a charge coupled device including a photo sensitive array and a horizontal read out shift register; and

a buffer memory means for storing the pattern signal to be transferred to said photosensitive array.
