Abstract
An image capturing device includes a housing and a processor. The processor is configured to determine whether a state of movement of the housing relative to an observation target is either a first state or a second state, and perform a control based on the state of the movement of the housing to cause change in electric energy for drive of the image capturing device.
Claims4
An image capturing device comprising:
- a camera configured to perform live preview image capturing of a skin surface at a predetermined frame rate while being moved relative to the skin surface;
- a sensor configured to detect, as a state of movement of the camera relative to the skin surface, a pressing force level at which an abutment is pressed against the skin surface, the abutment being to be pressed against the skin surface such that an optical path distance between the skin surface and an image capturing element is a predetermined distance;
- and
- a processor configured to, when the pressing force level detected by the sensor is lower than a predetermined threshold, (i) set a readout pixel number that is a number of pixels to be read in each frame to be lower than the readout pixel number in a case in which the pressing force level is higher than or equal to the threshold and (ii) set the frame rate to be higher than the frame rate in the case in which the pressing force level is higher than or equal to the threshold, wherein
- the processor sets the frame rate and the readout pixel number such that a value obtained by integrating the frame rate and the readout pixel number in the case in which the pressing force level is lower than the threshold is equal to a value obtained by integrating the frame rate and the readout pixel number in the case in which the pressing force level is higher than or equal to the threshold, thereby performing setting such that electric energy for drive of the camera in the case in which the pressing force level is higher than or equal to the threshold is lower than electric energy for drive of the camera in the case in which the pressing force level is lower than the threshold.

A non-transitory computer-readable recording medium storing a program, the program causing a computer for control of a camera configured to perform live preview image capturing of a skin surface at a predetermined frame rate while being moved relative to the skin surface to function as:
- a sensor configured to detect, as a state of movement of the camera relative to the skin surface, a pressing force level at which an abutment is pressed against the skin surface, the abutment being to be pressed against the skin surface such that an optical path distance between the skin surface and an image capturing element is a predetermined distance;
- and
- a processor configured to, when the pressing force level detected by the sensor is lower than a predetermined threshold, (i) set a readout pixel number that is a number of pixels to be read in each frame to be lower than the readout pixel number in a case in which the pressing force level is higher than or equal to the threshold and (ii) set the frame rate to be higher than the frame rate in the case in which the pressing force level is higher than or equal to the threshold, wherein
- the processor sets the frame rate and the readout pixel number such that a value obtained by integrating the frame rate and the readout pixel number in the case in which the pressing force level is lower than the threshold is equal to a value obtained by integrating the frame rate and the readout pixel number in the case in which the pressing force level is higher than or equal to the threshold, thereby performing setting such that electric energy for drive of the camera in the case in which the pressing force level is higher than or equal to the threshold is lower than electric energy for drive of the camera in the case in which the pressing force level is lower than the threshold.
