Imaging apparatus, method of controlling the imaging apparatus, and non-transitory computer-readable storage medium

A method of controlling an imaging apparatus that amplifies signal voltage resulting from voltage conversion of signal charge obtained by photoelectric conversion of an optical image of an object and then performs digital conversion to the signal voltage, comprising:

• amplifying the signal voltage using two or more amplification factors;
• determining weights for the respective signals subjected to the digital conversion after the amplification based on the two or more amplification factors;
• and
• combining the two or more signals subjected to the digital conversion after the amplification using the weights.

A non-transitory computer-readable storage medium for storing a program causing a computer to perform a method of controlling an imaging apparatus that amplifies signal voltage resulting from voltage conversion of signal charge obtained by photoelectric conversion of an optical image of an object and then performs digital conversion to the signal voltage, the program causing the computer to perform:

• amplifying the signal voltage using two or more amplification factors;
• determining weights for the respective signals subjected to the digital conversion after the amplification based on the two or more amplification factors;
• and
• combining the two or more signals subjected to the digital conversion after the amplification using the weights.
