1. A signal processing device, comprising:
- a memory; and
a processor coupled to the memory and configured to;
receive time series information related to an operation of a user from a camera,extract first time series information from the time series information,determine whether the first time series information is recognized as a particular type of operation, based on a recognition condition,extract second time series information prior to the first time series information from the time series information when the first time series information is recognized as the particular type of operation according to the determining, the second time series information being similar to the first time series information,change the recognition condition so that the second time series information is recognized as the particular type of operation, andexecute a recognition processing to another time series information based on the changed recognition condition, when the another time series information is received from the camera.

Abstract
A signal processing device includes: a memory; and a processor coupled to the memory and configured to: detect a second feature value relating to a first feature value recognized to satisfy a recognition condition, from a second time series prior to a first time series of the first feature value in a times series of a feature value corresponding to an input signal, and change the recognition condition so that the second feature value is recognized as a class for recognizing the first feature value.

18. A non-transitory computer-readable storage medium storing a signal processing program that causes a computer to execute a process, the process comprising:
-
receiving time series information related to an operation of a user from a camera; extracting first time series information from the time series information; determining whether the first time series information is recognized as a particular type of operation, based on a recognition condition; extracting second time series information prior to the first time series information from the time series information when the first time series information is recognized as the particular type of operation according to the determining, the second time series information being similar to the first time series information; changing the recognition condition so that the second time series information is recognized as the particular type of operation; and executing a recognition processing to another time series information based on the changed recognition condition, when the another time series information is received from the camera.
