Claim 0:
1. A biological sample detection device which analyzes a biological sample housed in a biological sample tube to which a colored label is attached, comprising:
an imaging device which takes and outputs a color image of the biological sample tube;
a storage device which stores a program to perform prescribed image processing on the color image; and
a processor which reads the program from the storage device and performs the prescribed image processing,
wherein the processor configured to perform:
a colored label presence determining process to determine whether or not a colored label is present on the biological sample tube, according to color information of the color image;
a label extracting process to extract the colored label determined to be present by the colored label presence determining process, from the color image;
a detection object region extracting process to remove the colored label from the color image and to extract a detection object; and
an analyzing process to acquire color information of the detection object region and to analyze a liquid amount and type of the biological sample,
wherein the imaging device is further configured to acquire and output a plurality of frames of color images of the biological sample tube,
wherein the processor is further configured to set a plurality of regions of interest each having a specified pixel size for each of the plurality of frames of color images, and to perform a color information acquiring process to acquire color information including information on brightness, hue, and saturation as the color information of each region of interest, and
wherein at least one of the plurality of regions of interest is set within the colored label, and at least one of the plurality of regions of interest is set within the detection object region.
