Image capturing apparatus

An image processing apparatus comprising at least one processor programmed to perform operations of

• a generator that generates a color image having an expanded dynamic range using a first image signal and a second image signal,
• wherein the first image signal is obtained by picking up a subject image with a first image sensor having a plurality of pixels each counts a number according to entering photons and outputs a count value, and
• the second image signal is obtained by picking up the subject image at same timing as the first image signal with a second image sensor having a plurality of pixels each outputs an electric signal corresponding to a charge amount obtained by performing photoelectric conversion on entering light,
• wherein the first image signal and the second image signal each has a plurality of different color components, and
• wherein the generator performs processing of
• selecting the first image signal in a case where a luminance value of the entering light is less than a predetermined first threshold value,
• selecting and synthesizing the first and second image signals in a case where the luminance value is equal to or greater than the predetermined first threshold value and less than a predetermined second threshold value which is larger than the predetermined first threshold value, and
• selecting the second image signal in a case where the luminance value is equal to or greater than the predetermined second threshold value.
