Cell classification apparatus capable of displaying a scene obtained by superimposing a character scene and graphic scene on a CRT

Claim 2

An image display apparatus for simultaneously viewing data and image information concerning a sample to be measured, comprising: a picture-scene signal generator means for generating a video image signal representing an image picture scene for displaying an image of the sample being measured; a character-scene signal generator means for generating a video data signal representing a data character scene for displaying data regarding said sample, with the data correlated to the sample as it is when simultaneously appearing in said image; adder means connected to said two signal generator means to superimpose the entire video image signal with the entire video data signal so that they do not interfere with each other thereby generating a sum video signal representing a superposed single scene; and display means connected to said adder means to display said superposed single scene composed of the superposed entire image picture scene and entire data character scene each transparent to the other in response to the application of said sum video signal.

Claim 3

An image display apparatus according to claim 1, wherein at least one of said character scene and said picture scene signal generator means generates three video signals of three primary colors to said display means.

Claim 4

An image display apparatus according to claim 1, wherein said adder means multiplies said two video signals by predetermined weights respectively and superposes said weighted video signals.

Claim 5

An image display system according to claim 1, wherein said adder means includes at least one operational amplifier to which said video signal representing the character scene and said video signal representing the picture scene are applied as a pair of inputs.

Claim 6

An image display apparatus according to claim 3, wherein said adder means includes an operational amplifier to which said two video signals are applied as inputs, and said weights for said video signals are determined by adjusting input resistors and a feedback resistor associated with said operational amplifier.

Claim 7

An image display system according to claim 3, wherein said two video signals are digital signals, and said adder means is a digital adder which multiplies at least two digital video signals by weights respectively and adds the weighted signals to each other.

Claim 8

An image display apparatus according to claim 1, further comprising switch means inserted between said two signal generators and said adder means to selectively interrupt said two video signals.

Claim 9

An image display apparatus according to claim 7, wherein said switch means includes a plurality of analog switches, and said adder means further includes latch means for selectively controlling on-off of said plural analog switches.

Claim 10

An image display apparatus for simultaneous viewing of data and image information concerning a sample to be measured, comprising: a character-scene signal generator means including a computer system, a CRT controller and a memory to generate a character video data signal representing an entire data character scene displaying data regarding the sample being measured; a picture-scene signal generator means including camera means picking up an image of the sample to generate an image video signal representing an entire image picture scene displaying the image of the sample at the location on the sample where the data is measured and at the time of the data character video signal generating; adder means adding said video data signal representing the entire data character scene and generated from said character-scene signal generator means to said image video signal representing the entire image picture scene and generated from said image-scene signal generator means to superimpose the entire image video signal with the entire video data signal so that they do not interfere with each other, thereby generating a sum video signal representing the result of addition of the entire data character scene and the entire image picture scene; and a display device displaying said sum signal applied from said adder means as a single visible display scene composed of the superimposed entire image picture scene and entire data character scene each transparent to the other.

Claim 11

An image display apparatus for simultaneous viewing of data and image information concerning a sample to be measured, comprising: a character-scene signal generator means including a computer system, a CRT controller and a memory to generate a character video data signal representing an entire data character scene displaying data regarding the sample being measured; a picture-scene signal generator means including camera means picking up an image of the sample to generate an image video signal representing an entire image picture scene displaying the image of the sample at the location on the sample where the data is measured and at the time of the data character video signal generating; adder means adding said video data signal representing the entire data character scene and generated from said character-scene signal generator means to said image video signal representing the entire image picture scene and generated from said image-scene signal generator means to superimpose the entire image video signal with the entire video data signal so that they do not interfere with each other, thereby generating a sum video signal representing the result of addition of the entire data character scene and the entire image picture scene; and a display device displaying said sum signal applied from said adder means as a single visible display scene composed of the superimposed entire image picture scene and entire data character scene each transparent to the other.

Claim 12

An image display apparatus according to claim 9, wherein said camera means is a TV camera, and said sample is a blood sample whose blood-cell image is picked up by said TV camera.

Claim 13

An image display apparatus according to claim 1, wherein said character video signal and said picture video signal are disintegrated into three primary color signals, and pairs of said primary color signals are added by said adder means.

Claim 14

An image display apparatus according to claim 1, wherein said sample is a blood sample whose blood cells are to be measured.

Claim 15

An image display apparatus according to claim 3, wherein said adder means includes means for changing each of said weights for said two video signals.
