摘要: An image taking apparatus, which can reduce the power consumption of total system apparatus without deteriorating quality when an is displayed on a liquid crystal display (LCD), provided. In quantization bit number at analog to digital (A/D) converter and signal processing processor (DSP) are variable. With this, LCD displaying mode that video signals LCD, A/D reduced also DSP same converter. this operation, mode, reduced, therefore largely reduced.
