Claim 3:
4. The method according to claim 3, 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 preset exposure time is increased to the target exposure time and the preset gain parameter is decreased to the target gain parameter, or the target exposure time is the preset exposure time and the preset gain parameter is decreased to the target gain parameter, or the preset exposure time is decreased to the target exposure time and the preset gain parameter is decreased 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 target exposure time is the preset exposure time, and the target gain parameter is 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 preset exposure time is increased to the target exposure time and the preset gain parameter is increased to the target gain parameter, or the target exposure time is the preset exposure time and the preset gain parameter is increased to the target gain parameter, or the preset exposure time is decreased to the target exposure time, and the preset gain parameter is increased to the target gain parameter.
