Abstract
Abstract There is provided a blood cell identification and classification system including a photographing means for producing magnified images of cells in blood smears and generating video signals and an automatic analytical means for analyzing cells based on said video signals, characterized in that said system comprises: a video recording means for recording on a collective basis the magnified images of unknown cells which could not be analyzed by said automatic analytical means in conjunction with identification data for smears to which said unknown cells pertain, a video reproduction means for reproducing the magnified images of unknown cells and identification data so recorded, and an input means for entering analytical data derived from the magnified images of unknown cells so reproduced.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A blood cell identification and classification system having a photographing means for producing magnified images of cells in blood smears and generating video signals and an automatic analytical means for analyzing cells based on said video signals, characterized in that said system comprises: a video recording means for recording on a collective basis the magnified images of unknown cells which could not be identified by said automatic analytical means in conjunction with identification data for smears to which said unknown cells pertain, a video reproduction means for reproducing the magnified images of unknown cells and identification data so recorded, and an input means for entering analytical data derived from the magnified images of unknown cells so reproduced.
Claim 2
Dependent Claim
117 words
A blood cell identification and classification system having a photographing means for producing magnified images of cells in blood smears and generating video signals and an automatic analytical means for analyzing cells based on said video signals, characterized in that said system comprises: a video recording means for recording on a collective basis the magnified images of unknown cells which could not be identified by said automatic analytical means in conjunction with identification data for smears to which said unknown cells pertain, a video reproduction means for reproducing the magnified images of unknown cells and identification data so recorded, and an input means for entering analytical data derived from the magnified images of unknown cells so reproduced.
Claim 3
Dependent Claim
45 words
A blood cell identification and classification system according to claim 1 which is further characterized in that said system includes an operational means for adding data entered by said input means to analytical data from said automatic analytical means so as to provide total data.
Claim 4
Dependent Claim
43 words
A blood cell identification and classification system according to claim 1 which is further characterized in that said video recording means is adapted to record analytical data generated by said automatic analytical means on cells identified and classified by said automatic analytical means.
Claim 5
Dependent Claim
94 words
A blood cell identification and classification system according to claim 1 which is further characterized in that said system includes: a memory means for storing the cordinates of unknown cells in smears in sequence as each unknown cell appears in the course of automatic analysis and a means which, after completion of analysis of a predetermined number of cells or blood elements, reads out the cordinates of unknown cells stored in said memory means in sequence and brings back said unknown cells one by one in the field of view of said photographing means.
Claim 6
Dependent Claim
92 words
A blood cell identification and classification system according to claim 1 which is further characterized in that said identification data includes the identification number of each smear and the information representing the number of unknown cells in the corresponding smear, that said input means includes judgement input keys corresponding to different types of unknown cells and that said video reproduction means is so adapted that when the number of operations of said judgement input keys has become equal to the number of said unknown cells reproduced, it starts reproducing the next smear.
