Abstract

Official abstract text for this publication.

According to one embodiment, a camera module has an exposure control unit. When an exposure error has reached within a coring range by first exposure control, the exposure control unit switches exposure control from the first exposure control to second exposure control. The exposure error shows a deviation of an exposure evaluation value to an exposure target value. In the second exposure control, an exposure change amount is reduced than at the time of the first exposure control. When the exposure error has reached a zero level by the second exposure control, the exposure control unit stops the exposure control.

First claim

Opening claim text (preview).

What is claimed is: 1. A camera module comprising: circuitry configured to execute a light amount measurement using an image signal obtained by picking up an object image and generate an exposure evaluation value that is a result of measurement of the light amount, calculate an exposure error showing a deviation of the exposure evaluation value to an exposure target value for achieving a correct exposure, and execute exposure control in an exposure change amount according to…
