## Abstract

In some aspects, the present disclosure relates to a method for identifying the type of the unit by camera.

## Claims

### Claim at position 1

1-36. (canceled)

### Claim 37

A chip comprising: a) a substrate, b) a unit on the substrate, and c) a color block having a color characteristic value (CCV) that identifies the unit.

### Claim 38 (depends on 37)

The chip of claim 37, wherein the chip is rectangular or round.

### Claim 39 (depends on 37)

The chip of claim 37, wherein the unit is a reaction unit in which one or more chemical or biological reactions can occur.

### Claim 40 (depends on 37)

The chip of claim 37, which comprises a plurality of units on the substrate and a plurality of color blocks, each of the color blocks identifying one of the plurality of units.

### Claim 41 (depends on 40)

The chip of claim 40, wherein units for substantially the same type of reaction are identified by color blocks of substantially the same CCV.

### Claim 42 (depends on 37)

The chip of claim 37, wherein the unit and the color block are arranged such that when the chip is moved in a direction, the trajectory of the unit and the trajectory of the color block do not completely overlap.

### Claim 43 (depends on 37)

The chip of claim 37, wherein the unit and the color block are arranged such that when the chip is moved in a direction, the trajectory of the unit and the trajectory of the color block do not overlap at all.

### Claim 44 (depends on 37)

A device comprising the chip of claim 37 and a camera system.

### Claim 45 (depends on 44)

The device of claim 44, wherein the camera system comprise a camera, an image processing unit, and/or a display unit.
