Classification: CPC G  H | IPC G  H

Claim 10:
11. The fingerprint identification apparatus according to claim 10, wherein the target capturing parameter comprises a target exposure time and a target gain parameter, and the preset capturing parameter comprises a preset exposure time and a preset gain parameter;
if the fingerprint identification environment is a strong light environment, a target product is a difference between a preset product and the adjustment amount, wherein the target product is a product of the target exposure time and the target gain parameter, and the preset product is a product of the preset exposure time and the preset gain parameter, the processor is configured to increase the preset exposure time to the target exposure time and decrease the preset gain parameter to the target gain parameter, or not adjust the preset exposure time and decrease the preset gain parameter to the target gain parameter, or decrease the preset exposure time to the target exposure time and decrease the preset gain parameter to the target gain parameter;
if the fingerprint identification environment is a normal environment, the adjustment amount is zero and the target product is the preset product, wherein the processor does not adjust the preset exposure time and the preset gain parameter; and
if the fingerprint identification environment is a specific environment, the target product is a sum of the preset product and the adjustment amount, wherein the processor is configured to increase the preset exposure time to the target exposure time and increase the preset gain parameter to the target gain parameter, or not adjust the preset exposure time and increase the preset gain parameter to the target gain parameter, or decrease the preset exposure time to the target exposure time and increase the preset gain parameter to the target gain parameter.
