Abstract
An image processing apparatus includes an AWB gain calculation section that calculates a WB gain Gs and a hysteresis gain Gh for every frame, a WB correction section that performs WB correction using Gh, a control section that causes the WB correction section to perform the WB correction using a fixed gain Gf during lock of white balance, and a gain adjustment section that weights and adds a WB gain Gs(n) and a correction hysteresis gain Gh'(n−1) to calculate a correction hysteresis gain Gh′(n) after unlock of the white balance, and the control section causes the WB correction section to perform WB correction for a frame n using Gh′(n).
