An image-taking apparatus changes a switching threshold value for switching between a color mode and a monochrome mode according to a maximum gain value set by a maximum gain setting unit so that switching between the color and monochrome modes can be optimally performed regardless of setting of the maximum gain value. The image-taking apparatus includes a threshold value correction unit configured to correct the switching threshold value according to the maximum gain value. The threshold value correction unit sets the switching threshold value with the maximum gain value set larger than an initial value to be smaller than the switching threshold value with the maximum gain value set smaller than the initial value. |
