Handheld code reader having a motion sensor

A method for use with a code reader, the method comprising:

• providing an image acquisition system, the image acquisition system acquiring low resolution images and high resolution images, and acquiring a brightness level for at least one of the low resolution images and high resolution images;
• providing a sensor detecting motion of the code reader;
• providing a processor operatively coupled to the image acquisition system and the sensor, the processor performing the steps of:
• instructing the image acquisition system to acquire a first image at a first exposure time;
• determining if a brightness level of the first image at the first exposure time provides an acceptable exposure time for image decoding;
• determining if a motion level of the code reader is above or below a motion level threshold, the motion level threshold based on the acceptable exposure time;
• when the motion level of the code reader is below the motion level threshold, and when the exposure time provides the acceptable exposure time, determining if the first image is a low resolution image or a high resolution image;
• and
• if the first image is a high resolution image, attempting to decode the high resolution image.

A system comprising:

• an image acquisition system, the image acquisition system to acquire a plurality of images;
• a sensor to detect motion of the image acquisition system;
• and
• a processor operatively coupled to the image acquisition system and the sensor, the processor to perform the steps of:
• instructing the image acquisition system to acquire a first image at a first exposure time, wherein the first image has a first resolution;
• determining if a brightness level of the first image at the first exposure time provides an acceptable exposure time for image decoding;
• determining if a motion level of the image acquisition system during acquisition of the first image is above or below a motion level threshold, the motion level threshold based on the acceptable exposure time;
• when the motion level of the image acquisition system is below the motion level threshold, and when the first exposure time provides the acceptable exposure time,
• determining if the first image is a low resolution image or a high resolution image based on the first resolution;
• when the first image is the low resolution image, instructing the image acquisition system to acquire a second image at the first exposure time, wherein the second image has a second resolution that is higher than the first resolution;
• and
• attempting to decode the second image.
