Abstract: A circuit device includes a storage unit configured to store a plurality of lookup tables, and a luminance information calculation circuit configured to calculate luminance information indicating a luminance of light reaching a target pixel of a display panel from a backlight. The first lookup table is associated with a first light source element provided at a first position, and indicates a first attenuation rate distribution of the first light source element. The second lookup table is associated with a second light source element provided at a second position, and indicates a second attenuation rate distribution of the second light source element.

Abstract: The present technology relates to a signal processing apparatus, a control method, an image pickup element, and an electronic appliance that achieve the suppression of an increase in electric power consumption. The signal processing apparatus may be configured to control an amount of electric current at a differential stage in a comparison unit that compares signal levels of a plurality of signals and reduce the amount of electric current for a period other than this comparison period. For example, the amount of electric current may be reduced by turning off part of a group of switches each capable of disconnecting a path of an electric current from an electric current source. In addition, for example, the amount of electric current may be reduced by causing a gate potential at the electric current source unit to decrease. The present technology can be applied to, for example, an image pickup element and an electronic appliance.
